Abstract
The technical evolution of the surgery for spina bifida occulta (SBO) over the course of a half-century was reviewed with special foci placed on the spinal lipoma and tethered spinal cord. Looking back through history, SBO had been included in spina bifida (SB). Since the first surgery for spinal lipoma in the mid-nineteenth century, SBO has come to be recognized as an independent pathology in the early twentieth century. A half-century ago, the only option available for SB diagnosis was the plain X-ray, and pioneers of the time persevered in the field of surgery. The classification of spinal lipoma was first described in the early 1970s, and the concept of tethered spinal cord (TSC) was proposed in 1976. Surgical management of spinal lipoma with partial resection was the most widely practiced approach and was indicated only for symptomatic patients. After understanding TSC and tethered cord syndrome (TCS), more aggressive approaches became preferred. A PubMed search suggested that there was a dramatic increase of publications on the topic beginning around 1980. There have been immense academic achievements and technical evolutions since then. From the authors' viewpoint, landmark achievements in this field are listed as follows: (1) establishment of the concept of TSC and the understanding of TCS; (2) unraveling the process of secondary and junctional neurulation; (3) introduction of modern intraoperative neurophysiological mapping and monitoring (IONM) for surgery of spinal lipomas, especially the introduction of bulbocavernosus reflex (BCR) monitoring; (4) introduction of radical resection as a surgical technique; and (5) proposal of a new classification system of spinal lipomas based on embryonic stage. Understanding the embryonic background seems critical because different embryonic stages bring different clinical features and of course different spinal lipomas. Surgical indications and selection of surgical technique should be judged based on the background embryonic stage of the spinal lipoma. As time flows forward, technology continues to advance. Further accumulation of clinical experience and research will open the new horizon in the management of spinal lipomas and other SBO in the next half-century.

Abstract
PURPOSE To investigate the association of spinal anomalies with lumbar spondylolysis and spina bifida occulta (SBO). METHODS A total of 1190 patients with thoracic, abdominal, and pelvic computed tomography scans available were categorized according to the number of presacral (thoracic and lumbar) mobile vertebrae and the presence or absence of lumbosacral transitional vertebrae (LSTV). The prevalence of spondylolysis and SBO and the association of spinal anomalies with these disorders were evaluated. RESULTS Normal morphology (17 mobile vertebra with no LSTV) was found in 607 men (86.5%) and 419 women (85.9%) and about 14% of patients had anomalies. Spondylolysis was found in 74 patients (6.2%), comprising 54 men (7.7%) and 20 women (4.1%). SBO involving the lumbar spine was found in 9 men (1.3%) and 2 women (0.4%). Spondylolysis was significantly more common in men with 18 vertebrae without LSTV (21.1%) than in those with 17 vertebrae without LSTV (7.2%) (p = 0.002). The prevalence of spinal anomalies was 55.6% in men and 50.0% in women with SBO that included a lumbar level was significantly higher than in both men (13.5%, p < 0.001) and women (4.8%, p = 0.003) without SBO. CONCLUSION These findings indicate that there is a relationship between spinal anomalies and both spondylolysis and SBO, which may lead to elucidation of the mechanism of onset of spondylolysis and improve its treatment and prognosis. Awareness that patients with SBO involving the lumbar spine have an increased likelihood of a spinal anomaly may help to prevent level errors during spinal surgery.

Abstract
Objectives Recurrent bacterial meningitis (RBM) is a rare but life-threatening disease. This study aims to analyze the clinical features, potential causes, and therapeutic outcomes of RBM in children. Methods This article retrospectively reviews the clinical characteristics, etiologies, and treatments in children with RBM hospitalized in Hebei children's hospital from 2012 to 2020. Results A total of 10 children with RBM, five males and five females, were included in this study. The age of RBM in children spans from the neonatal stage to the childhood stage. The underlying illnesses were identified and classified as cerebrospinal fluid rhinorrhea (1 case), humoral immunodeficiency with Mondini dysplasia (1 case), common cavity deformity with cerebrospinal fluid ear leakage (1 case), Mondini malformations (2 cases), incomplete cochlear separation type I with a vestibular enlargement (2 cases), local inflammation of the sphenoid bone caused by cellulitis (1 case), congenital skull base defects (1 case), and congenital dermal sinus with intraspinal abscess (1 case). 6 patients chose targeted therapy for potential reasons. Conclusions Congenital abnormalities or acquired injuries lead to intracranial communication with the outside world, which can quickly become a portal for bacterial invasion of the central nervous system, resulting in repeated infections.

Abstract
We report the case of a patient with spinal immature teratoma and cerebrospinal fluid leakage from the congenital dermal sinus tract. A 0-day-old female infant presented with a subcutaneous soft mass with a dimple in the lumbosacral region at birth. Magnetic resonance imaging revealed a mixed low-intensity mass located in the extraspinal and intraspinal canal with a sinus tract. The reconstructed three-dimensional spinal computed tomography image showed spina bifida and ectopic ossification at the dorsal aspect of the sacrum. Urgent removal of the tumor and dermal sinus tract was then performed under evoked electromyography monitoring. The resected tumor was histopathologically diagnosed as immature teratoma.

Abstract
INTRODUCTION Dermal sinus tracts are rare congenital abnormalities characterized by an epithelium-lined tract that extends from the subcutaneous tissue to the underlying thecal sac or neural tube. These developmental anomalies can present asymptomatically with a cutaneous dimple or with devastating complications including recurrent episodes of meningitis, or neurological complications including paralysis. Dermal sinus tracts generally occur as single lesions, and the presentation of midline double dermal sinus tracts of the cervical and thoracic regions has not been previously described. METHODS Here, we present the case of a 3-year-old girl suffering from recurrent episodes of myelitis, paraparesis, and intramedullary intradural masses, who was diagnosed with double dermal sinus tracts of the cervical and thoracic regions. We also present a summary of all previous reported cases of multiple dermal sinus tracts. RESULTS Our patient was successfully treated surgically and is now 2 years status post her last procedure with a significant improvement in her neurologic function and normal muscle strength and tone for her age, and there was no recurrence of her symptoms. CONCLUSIONS Early treatment with prophylactic surgery should be performed when possible, but removal of these lesions once symptoms have arisen can also lead to success, as in the case presented here. Complete excision and intradural exploration is required to excise the complete tract.

Abstract
INTRODUCTION Multiple neural tube defects and pontine anomalies are relatively rare. Cases of split pons and double encephalocoeles in combination with other spinal anomalies are even rarer. CASE REPORT Here, we present a very rare case of split pons, twin encephalocoeles (one of which was atretic), lumbar dermal sinus tract, lumbosacral lipomeningomyelocele, thickened filum, and syringomyelia that was managed successfully at our institute. CONCLUSION Cases of split pons and double encephalocoeles in combination with other spinal anomalies are very rare, and to the best of author's knowledge, this is the first case report of these multiple anomalies in world literature.

Abstract
A 14-year-old boy presented with symptomatic high-grade dysplastic type spondylolisthesis, with a presence of spina bifida occulta, not diagnosed by plain radiographs, but confirmed on preoperative CT and MR. Circumferential fusion with partial reduction of L5/S1 was performed. Awareness of the coexistence of spondylolisthesis and spina bifida by an accurate preoperative planning is paramount to avoid iatrogenic damage to neural elements during surgery.

Abstract
The problem of low back pain (LBP) in children is very common and many specialists are dealing with it in everyday practice. The cause for low back pain often is not found and classified under the diagnosis of non specific low back pain. The objective of this prospective study is to determine wether children with non specific low back pain and existence of anomalies in LS spine (transitional vertebra- TV and/or Spina bifida occulta SBO) also have the degeneration of the intervertebral disc (DD) L4-L5 and/or L5-S1. This prospective study included 69 patients from 8 to 16 years of age (X 12.81) of whom 40 were male (57.97%), and 29 female (42.03%). They all were examinated in University of Zagreb, "Sestre milosrdnice" University Hospital Center, Zagreb Children's Hospital, Department of Orthopaedic, Zagreb, Croatia. The reason of their visit was non specific low back pain. Pain was measured by visual analog scale (VAS) and mean score was three, duration of pain was between two and four weeks. Also, pain was sporadic, during daytime and not connected with level of physical activity. They all have undergone an algorithm of radiological examinations. Standard AP and LL radiographs (RTG) were made, as well as magnetic resonance (MR) of LS spine and sacrum in sagittal and transversal plane in T1 and T2 weighted sequence. The anomalies of L5 and S1 were found in 65 patients: transitional vertebra classified according to Castellvi et al. and SBO. In MRI in T2 weighted sequence DD was found in 61 patients which was classified modified from Pearce. Data analysis and comparison showed that 56patients with TV and/or SBO have changes on vertebral dynamic segment L5-S1 (VDS) and that means DD. In 13 patients only DD or spinal anomaly (TV and/or SBO) were found. Correlation between anomalies and DD in those patients was established by McNemar analysis and has shown significant difference (p=0.581) in favour of the patients with anomaly and DD. This has established that all of 56 patients with spinal anomaly could have DD as known cause of LBP.

Abstract
A section of the filum terminale (SFT) is used for the surgical treatment of isolated tethered cord or that resulting from neurulation disorders. More recently, it has been proposed for the management of the occult tethered cord syndrome (OTCS), though it is still under debate. Even more controversial appears to be the use of SFT in patients with Chiari type I malformation (CIM), which is based on the possible presence of OTCS. This review shows that: (1) there are issues both in favor and against the occurrence of OTCS, (2) there is no significant correlation between CIM and tethered cord, the old "caudal traction theory" being not supported by clinical or experimental evidences. On these grounds, a relationship between CIM and OTCS is hard to be demonstrated, (3) a subgroup of patients with CIM suffering from OTCS may exist and benefit from SFT.

Abstract
A dermal sinus is a congenital defect arising from a closure failure of the neural tube that results in different degrees of communication between the skin and the central nervous system. A dermal sinus can occur anywhere from the root of the nose to the conus medullaris, and the occipital location is the second most common. Dermal sinuses are often found in association with dermoid or epidermoid cysts and less frequently with teratomas. Patients with an occipital dermoid cyst associated with a dermal sinus can develop meningitis and/or abscesses as the first clinical manifestation of the disease due to the dermoid cyst itself becoming abscessed or to the formation of secondary abscesses; few cases of the formation of secondary abscesses have been reported. We present a case of a dermoid cyst associated with an infected dermal sinus and posterior development of cerebellar abscesses and hydrocephalus.

Abstract
PURPOSE Congenital dermal sinus tract (DST), an uncommon entity of cranial or spinal dysraphism, occurs along the midline neuraxis that may arise from nasion and occiput down to the lumbar and sacral region. It is often diagnosed in infants and children for skin signs, neurological deficits, local infection, meningitis, or abscess. For spinal DST, there is a paucity of case or series report in Taiwan. CASE REPORT In this paper, we report a case in a 6-year-old girl. The girl presented with midline lumbar skin dimple, hypertrichosis, and history of bacterial meningitis. She was successful treated by surgical excision of the DST with local infection that ended within the subarachnoid space between L2-3 vertebrae. CONCLUSION This case highlights the importance of a thorough examination of the midline craniospinal axis in children with meningitis or history of meningitis.

Abstract
BACKGROUND Diastematomyelia is a type of dysraphism with a double or bifid spinal cord divided by an osseous septum. This defect often co-occurs with other developmental disorders of the skull or the atlanto-occipital junction. The course may be benign or aggressive. 2. CASE REPORTS We describe two female patients treated in the Rehabilitation Clinic and the Orthopaedic Department at the Medical University of Lublin in the years 2004 - 2009. The first patient was diagnosed at the age of 20 years to have diastematomyelia at the L3 level and spina bifida occulta at L1- S5 and at the C1 arch. In the other patient, diastematomyelia at the L3 level and spondylolisthesis at L5-S1 were found at the age of 14 years. Initially both patients were treated for lumbosacral radicular syndromes. Physiotherapy intensified the pain. The patient with diastematomyelia and L5-S1 spondylolisthesis had L5-S1 segment stabilization performed at the age of 16. The pain subsided after the surgery. The other patient was instructed to stop rehabilitation, follow a balanced lifestyle, and refrain from physical work, which eliminated the pain. DISCUSSION Managing a patient with diastematomyelia demands caution. Diagnosis of this defect requires a thorough cause-and-effect analysis of the presenting signs and symptoms of spinal dysfunction. The treatment should be dependent on local pain intensity (which is often not directly associated with the disorder) and on the degree of neurological dysfunction. 5. CONCLUSIONS 1. A thorough clinical evaluation with spinal imaging prior to elective surgery for scoliosis and other spine deformities should be a standard procedure undertaken in order to avoid complications. 2. The treatment for diastematomyelia should depend on the intensity of local pain and on the level of neurological dysfunction. 3. Broadly understood rehabilitation is not always effective, often increasing the pain and/or neurological complaints.

Abstract
The purpose of this paper was to model the human gait of typical subjects and patients with such deformities of lower limbs as: spastic diplegia cerebral palsy and spina bifida occulta. Model coefficients will lead to the development of a better computer system to support clinical decision-making in human gait in terms of assessment, diagnosis, and classification. Human gait was evaluated by using Motion Analysis System in the Syncrude Center for Motion and Balance in Edmonton. Kinetics data were used for the mathematical modelling based on regression function. The difference between the model coefficients of the patients with the deformities of lower limbs and typical subjects were analysed. There is shown that the model coefficients are different in each group. The modelling can help to define gait pathology and treatment for a large number of patients.

Abstract
Congenital dermal sinuses, resulting from abnormal neurulation, are relatively uncommon and cause the patients to contract intraspinal infection. Sometimes, this intraspinal infection develops intramedurally abscess with severe neurological deficits. Therefore, a lack of awareness about this problem can result in fatal neurological sequelae. We report the case of a 1-year-old boy who had a lumbo-sacral dimple at birth without further evaluation. He presented repeated fever and rapidly progressive paraplegia. MRI showed a huge intraspinal and intramedullary abscess with dermoid, which was thought to be the result of a dermal sinus. Subsequently, he was transferred to our hospital and received immediate surgery. The patient underwent irrigation of purulent material in the intraspinal abscess including on intramedullary lesion, removal of dermoid tumor, and the resection of the dermal sinus. After that, he was treated with 8 weeks of antibiotic therapy. The patient remained paraplegia but made improvement. This patient illustrates the importance of the recognition and evaluation of skin markers. Prophylactic surgery is indicated to prevent dangerous and recurrent infections of the central nervous system.

Abstract
AIM The aim of the study was to investigate the relationship between the clinical evidence of foot deformities in spina bifida occulta and the associated neurophysio-logical damage. METHODS The authors studied 47 patients with foot deformities (37 flat foot, 10 pes cavus) and vertebral cleft, variably associated with enuresis, midline cutaneous lesions, and further orthopaedic deformities. An electrophysiological evaluation was performed in an attempt to investigate the peripheral nervous system in greater detail, including conventional motor and sensory nerve conduction, F-wave recording and electromyogram (EMG) testing. RESULTS The peroneal nerve F wave latency was longer in patients with pes cavus than in those with flat foot (P<0.04). Conversely, the posterior tibial nerve F-wave latency was longer in patients with flat foot than in those with pes cavus (P<0.02). Needle EMG showed large amplitude motor unit potentials during voluntary recruitment in all patients, suggesting a neurogenic origin of these EMG changes. Neurophysiological study makes it possible to distinguish between myogenic and lower motor neuron involvement. The existence of some degree of spinal cord dysraphism may be pathophysiologically associated with foot deformities. CONCLUSION Children with foot deformities and clinical evidence of occult spinal dysraphism should have a neuro-physiological assessment in order to obtain an early diagnosis and avoid ineffective foot surgery.

Abstract
BACKGROUND & AIMS Spina bifida occulta (SBO) is a common developmental variant. The aim of this study was to re-examine the possible association between SBO and constipation in children. METHODS A total of 113 children with constipation underwent plain abdominal radiography, anorectal manometry, neurophysiologic study, electromyography testing, and colonic transit study. Eighty-six were diagnosed with functional constipation (FC) and 27 were diagnosed with nonretentive fecal incontinence (NRFI). The incidence of SBO in these children was compared with 226 sex- and age-matched controls. Twenty-four SBO children with either FC or NRFI also underwent individualized biofeedback training and electric stimulation therapy based on the investigation results. RESULTS The incidence of SBO in the FC and NRFI groups was 47.7% and 77.8%, respectively. Statistically, this is significantly higher than that of the control group (chi-square, 23.9%; P < .05). Compared with the FC or NRFI children without SBO, the FC and NRFI children with SBO had decreased vector volumes and electromyography amplitudes, increased rectal sensory thresholds, and prolonged latency of pudendo-anal reflex. All 24 children who underwent individualized biofeedback training and electrical stimulation treatment had sustained symptomatic improvement with less straining, fewer incomplete bowel movements, and less abdominal pain. The recovery rate was 79.2% (19 of 24). CONCLUSIONS Constipation in children is associated with increased incidence of SBO. Individualized biofeedback combined with electrical stimulation improves both the symptoms and the objective anorectal function measurements.

Abstract
Human tail or tail-like caudal cutaneous appendage is a rare fingerlike, midline protrusion at the lumbosacrococcygeal region, often associated with occult spinal dysraphism. A 2-month-old male child presented here had a lumbosacral tail-like appendage with underlying spinal dysraphism without any appreciable neurological deficit. In contradiction to a previous report, true vestigial tails are not benign because they may be associated with underlying dysraphic state. About 50% of the cases were associated with either meningocele or spina bifida occulta. Management of such lesions must include complete neurological history and examination as well as magnetic resonance or computed tomographic imaging. After diagnosis, microsurgery should be performed if there is any intraspinal component to avoid any damage and neurological deficit.

Abstract
OBJECTIVE To explore the pathophysiological significance of spina bifida occulta (SBO) in non-retentive fecal incontinence (NRFI) in children. METHODS Twenty-seven children with NRFI diagnosed according to the Rome III criteria, 21 with SBO, aged (7.9 +/- 2.4) years, and 6 without SBO, aged (7.5 +/- 1.9) years, and 226 normal controls, aged (8.4 +/- 2.7) years, underwent plain X-ray photography, neurophysiological study, colonic transit test, electromyography (EMG), and anorectal manometry. The resting vector volume, squeezing vector volume, resting EMG amplitude, and squeezing EMG amplitude, which predominantly reflect internal and external anal sphincter function, were recorded. RESULTS The prevalence rate of SBO in the children with NRFI was 78%, significantly higher than that of the normal controls (24%). The resting vector volume, squeezing vector volume, resting EMG amplitude, and squeezing EMG amplitude, of the children with NRFI were all significantly lower than those of the normal controls; however, there were no significant differences in these indexes between the NRFI children with and without SBO. The total colonic transit time of the NRFI children with SBO was (41 +/- 17) h, significantly longer than those of the children without SBO and normal controls (24 +/- 5) h and (29 +/- 8) h, both P < 0.05]. Neurophysiologic test showed that the latency of pudendi-anal reflex of the NRFI children with SBO was (52 +/- 20) ms, significant longer than those of the NRFI children without SBO and normal controls [(29 +/- 9) ms and (23 +/- 7) ms respectively, both P < 0.05]. CONCLUSION SBO is a major cause of NRFI. Treatment should be focused on recovery of the functions of nervous system.

Abstract
PURPOSE Current practice at our institution is to recommend tethered cord release at diagnosis to prevent the onset or worsening of symptoms. Tethered cord release is frequently performed in children younger than 3 years who often have no urological manifestations. To our knowledge there are currently no long-term data on urological outcomes in this age group. MATERIALS AND METHODS We completed a retrospective review of 475 cases of tethered cord release performed at a single institution between 1995 and 2002. Of these surgeries 173 were performed in children younger than 3 years. Clinical outcomes, and preoperative and postoperative urodynamic and radiographic studies were evaluated. RESULTS A total of 79 patients met study criteria. Average age at surgery was 9.6 months and average followup was 5.2 years (range 6 months to 11.2 years). At followup 49 patients (62.1%) had no urological complaints and 30 (38%) had urological problems. A total of 20 children (25.3%) had minor problems (constipation, delayed toilet training or other) and 10 (12.7%) had major problems (need for clean intermittent catheterization, febrile urinary tract infection or reflux). Of 66 patients 30 (45.5%) had abnormal preoperative urodynamics. One of 31 patients (3.2%) had hydronephrosis on preoperative ultrasound. Statistical analysis revealed that abnormal preoperative urodynamics and ultrasound were not predictive of major urological problems. Lipomatous dysraphism and preoperative musculoskeletal symptoms positively correlated with major urological problems (p = 0.0076 and 0.0484, respectively). CONCLUSIONS The majority of children did not experience urological problems following tethered cord release. Only a small set of children had major urological problems. Children with lipomatous dysraphism and musculoskeletal symptoms were more likely to experience poor urological outcomes.

Abstract
Congenital dermal sinuses are relatively uncommon, and result from abnormal neurulation. A lack of awareness about this problem causes these patients to manifest significant mortality and morbidity. Spinal intramedullary abscesses are rare and potentially devastating lesions. Intraspinal epidermoids are also unusual lesions. We report on a boy, aged 1 year and 5 months, who had a lower-back hairy hemangioma at birth without further evaluation, and dermal sinus tract without surgical intervention at age 7 months. He also manifested rapidly progressive paraplegia with urine and stool retention, and was found to have a spinal intramedullary abscess with an epidermoid as the result of a dermal sinus. This patient illustrates the importance of the recognition and evaluation of skin markers, and of an awareness and complete neurological assessment of all patients with a congenital dermal sinus, because of the potential for intradural extension and a frequent association with other dysraphic abnormalities. Prophylactic surgery is indicated to prevent dangerous and recurrent infections of the central nervous system.

Abstract
CASE REPORT We present a case of a child born with a birthmark over the lumbar spine, which harbored a pinhole-sized opening. At 6 months of age the child presented with fever of unknown origin. Subsequent lower extremity pain resulted in imaging studies that revealed a spinal mass with extension into the posterior mediastinum. At operation, the child was found to have an infected dermal sinus tract. DISCUSSION This case highlights the importance of a thorough examination of the midline craniospinal axis in children with fever of unknown origin. To our knowledge, this is the first reported case of an infected dermal sinus tract with extension into the posterior mediastinum.

Abstract
Occipital dermal sinuses (ODSs) are congenital lesions located in the midline and characterized by a cutaneous pit or dimple. The intracranial extension as well as the associated symptoms are variable. To date, a familial occurrence of these lesions has not been reported. In this paper the authors report on a 2-year-old boy with an ODS and intracranial hypertension. The boy's mother had a similar lesion but did not have any complaints. Following their experience with this case and a literature review, the authors suggest that there may be a genetic basis in certain instances of ODS.

Abstract
Object
Children with spina bifida occulta require early surgery to prevent neurological deficits. The treatment of patients with a congenitally tethered cord who present in adulthood remains controversial.
Methods
The authors studied the medical records of 61 adult patients who underwent surgical untethering for spina bifida occulta at three institutions between 1994 and 2003. Patients who had undergone prior myelomeningocele repair or tethered cord release surgery were excluded.
The most common intraoperative findings were lipomyelomeningocele (41%) and a tight terminal filum (36%). The follow-up duration ranged from 10.8 to 149.5 months. Of the 34 patients with back pain, status improved in 65%, worsened in 3%, remained unchanged in 18%, and improved and later recurred in 15%. Lower-extremity pain improved in 16 patients (53%), remained unchanged in 23%, improved and then recurred in 17%, and worsened in 7%. Lower-extremity weakness improved in 47%, remained unchanged in 47%, and improved and then recurred in 5%. Finally, of the 17 patients with lower-extremity sensory changes, status improved in 35%, remained unchanged in 35%, and the information on five patients was unavailable. Surgical complications included three wound infections, one cerebrospinal fluid leak, and two pseudomeningoceles requiring surgical revision. One patient developed acute respiratory distress syndrome and sepsis postoperatively and died several days later.
Conclusions
Adult-age presentation of a congenital tethered cord is unusual. Despite a slight increase in postoperative neurological injury in adults, surgery has relatively low risk and offers good potential for neurological improvement or stabilization. As they do in children, the authors recommend early surgery in adults with this disorder. The decision to undertake surgery, however, should be modulated by other factors such as a patient's general medical condition and risk posed by anesthesia.

Abstract
OBJECTIVE We examined whether the existence of spina bifida occulta or ultrasonographic bladder abnormalities was related to the outcome of treatment for primary nocturnal enuresis in children. METHODS Between April 1996 and September 2005, a total of 77 subjects (53 boys and 24 girls, aged 5-18 years; mean age, 9.9 years) with primary nocturnal enuresis were studied. Plain X-ray films of the spine and ultrasonographic bladder measurements (bladder wall thickness, bladder neck descent and bladder neck opening) were obtained and the correlations with the outcome of treatment using imipramine hydrochloride were assessed. RESULTS On plain X-ray films of the spine, spina bifida occulta (lumbar vertebrae in three, lumbosacral vertebrae in 19 and sacral vertebrae in 31) was recognized in 53 children (69%). Ultrasonographic bladder abnormalities were recognized in 40 children (52%). Children with lumbar and lumbosacral spina bifida occulta showed a higher rate of concomitant ultrasonographic bladder abnormalities (P = 0.006) and had a poorer response to treatment (P = 0.041) compared with the children who had sacral spina bifida occulta. Children with ultrasonographic bladder abnormalities had a worse response to treatment (P = 0.005) compared to the children without bladder abnormalities. CONCLUSIONS The presence of lumbar spina bifida occulta and ultrasonographic bladder abnormalities was related to the outcome of treatment for primary nocturnal enuresis in children, suggesting that spinal radiography and vesical ultrasonography may be useful predictive tests.

Abstract
Lesions composed of Pacinian corpuscles or showing Pacinian corpuscle differentiation have usually been described in relation to benign tumours of the peripheral nervous system or reactive hyperplastic processes. On the other hand, mature Pacinian corpuscles have occasionally been detected as part of intraspinal lumbosacral lipomas, a rare developmental anomaly usually associated with spina bifida. A lesion of the cauda equina composed of numerous mature Pacinian corpuscles and nerve fascicles embedded in adipose tissue in association with spina bifida occulta is described in a 5-month-old male with a sacral red papula. Magnetic resonance imaging (MRI) revealed a cord-like mass in the region of the cauda equina, presumably connected to the subcutis. With the exception of a low lying, tethered spinal cord, there was no neurological deficit and the range of motor development was normal. In March 2005, at 17 months, surgery was carried out. A cord of yellow tissue was found running from the subcutis through the bone defect into the lumbosacral spinal canal. Intradurally, it ran parallel to the cauda equina, terminating at the conus medullaris. Fifteen months after the surgery the development of the child was normal. Only two similar cases have been reported so far. Due to their occurrence in the sacrococcygeal region and association with developmental anomalies, they have been regarded as malformations and the term Pacinioma has been suggested. Our case with clusters of Pacinian corpuscles may represent a rare variant of complex intraspinal lumbosacral lipomas, closely related to Paciniomas reported by Bale.

Abstract
PURPOSE Occult tethered cord syndrome applies to patients with signs and symptoms consistent with a caudal spinal cord malformation despite normal neuroimaging. Although several reports of successful surgical treatment exist, controversy remains with respect to patient selection and efficacy. We present a large series with excellent clinical followup, neuroimaging and urodynamic characterization. MATERIALS AND METHODS We present our experience with 36 patients at a single institution with preoperative clinical findings, neuroimaging and urodynamics available. Postoperative outcomes were assessed clinically and with urodynamics. We determined predictive parameters to improve patient selection. RESULTS Approximately 0.04% of pediatric urology clinic visits resulted in neurosurgical referral for the potential of an occult tethered cord. They occurred after failure of a mean of 2 years of aggressive medical management. Daytime urinary incontinence was present in 83% of patients and 47% had encopresis. Preoperative urodynamics were markedly abnormal in all patients with mean bladder capacity 55% of expected capacity. Clinical improvement in urinary symptoms was seen in 72% of patients with resolution of incontinence in 42%. Bowel symptoms improved in 88% of cases, including resolution of encopresis in 53% within 3 months of surgery. Urodynamic improvements were demonstrated in 57% of cases. We were unable to determine preoperative factors that were more likely associated with surgical success. CONCLUSIONS In a highly select population with severe urinary and fecal dysfunction sectioning a normal-appearing filum terminale can result in significant improvement. We were unable to identify factors that may increase the chance of surgical success.

Abstract
PURPOSE Tethered cord syndrome encompasses a group of clinical symptoms caused by abnormal spinal cord fixation. We evaluated a select cohort of patients with primary tethered cord syndrome in regard to urodynamic and clinical outcome after cord release. MATERIALS AND METHODS We retrospectively reviewed the records of patients with the diagnosis of tethered cord from May 2001 to October 2004. Patients were assessed preoperatively by standard urodynamic studies, which was repeated a mean of 6.4 months after tethered cord release. Clinical and urodynamic outcomes were analyzed. RESULTS Ten male and 14 female patients 1 month to 12 years old (median age 6 years) were evaluable. Preoperatively 14 of the 24 patients with a median age of 8.1 years were toilet trained and 7 (50%) had diurnal incontinence. Constipation was noted in 10 of 24 patients (42%) and urinary tract infections developed in 6 (25%). Postoperatively only 1 patient (7%) experienced diurnal incontinence (p = 0.04). Constipation was observed in 6 patients (25%) and urinary tract infections developed in 1 (4.2%) (p = 0.29 and 0.07, respectively). Ten of the 21 children (48%) with abnormal urodynamics had normalized studies postoperatively. Ten of the 17 patients with neurogenic detrusor overactivity achieved normalization and 7 remained unchanged. Two of 3 patients with normal preoperative urodynamics had neurogenic detrusor overactivity and 1 had poor bladder compliance. Four patients with low bladder capacity and/or low compliance preoperatively did not improve. CONCLUSIONS Our results suggest that tethered cord release is beneficial in terms of clinical and urodynamic outcomes. Patients with abnormal urodynamics had 48% improvement after tethered cord release. Neurogenic detrusor overactivity seems to respond better with 59% improvement in urodynamics. The level of the conus on magnetic resonance imaging did not seem to be predictive of urodynamic outcome. Patients with a normal bladder may show urodynamic deterioration postoperatively, which raises cause for concern.

Abstract
OBJECT The angulation of the sacrum is easily measured. The authors have previously reported on patients who were symptomatic with a diagnosis of myelomeningocele who were found to have changes in their lumbosacral angle (LSA) corresponding to the onset of symptoms indicative of a tethered spinal cord. The aim of this study was to verify this same finding in a group of patients with occult spinal dysraphism (that is, closed neural tube defect). METHODS A retrospective analysis of 50 consecutive lipomyelomeningocele repair procedures was performed. Data pertaining to 30 age-matched control patients were also analyzed. Measurements were made of the LSA over time in all studied patients harboring lipomyelomeningoceles. Appropriate imaging was available for 25 cases of lipomyelomeningocele (that is, radiographs of the lumbosacral junction were available from the patient's perinatal period and at presentation of symptoms of a tethered spinal cord). Roughly one third of these patients suffered symptoms from a tethered spinal cord at the most recent follow-up examination. Nine patients (36%) were found to have corresponding LSA measurements greater than 70 degrees, and seven (28%) of these patients presented with signs and symptoms of a tethered spinal cord, such as decreased lower-extremity function (two patients), urinary bladder incontinence (three patients), back pain (one patient), and lower-extremity paresthesias (one patient). The LSA measurements were statistically greater (p < 0.05) in the symptomatic patient population than in age-matched control patients and asymptomatic patients. Changes in the LSA in these symptomatic patients ranged from 5 to 24 degrees (mean 13 degrees). Changes in the LSA were noted in only two asymptomatic patients. No single sign or symptom of a tethered spinal cord appeared to correlate to any degree of increase in the LSA. Of the 25 patients excluded from this study because perinatal radiographic images were not available, none was symptomatic at the most recent follow-up examination and none had a grossly exaggerated LSA. CONCLUSIONS Signs and symptoms indicative of a tethered spinal cord appear to correspond to increases in the LSA. Although the authors do not advocate the use of LSA measurement as the sole indicator of a tethered spinal cord, this imaging finding may prove useful to the clinician as an indication of the tethered spinal cord or as an adjunct in verifying symptomatology in patients harboring a lipomyelomeningocele.

Abstract
BACKGROUND Hydrocephalus associated with intraspinal tumors constitutes a well-documented occurrence. The accepted mechanisms for this association seem to be well established. On the contrary, hydrocephalus in the context of intraspinal dermoids has been rarely recognized and its pathogenetic mechanism appears to be different. PATIENTS AND METHODS The authors report four pediatric cases of spinal dermoid tumors and dermal sinuses that developed hydrocephalus during the evolution of these congenital lesions of ectodermal origin. DISCUSSION In two children, the mechanism leading to the development of hydrocephalus consisted of leptomeningeal inflammation due to bacterial meningitis or to spillage of dermoid cyst contents in the cerebrospinal fluid spaces. We hypothesize that ventricular dilatation in the other two might be the result of chemical meningitis occurring during intrauterine life. Two cases developed ventriculomegaly prior to the diagnosis of their spinal cord disease. CONCLUSIONS The unusual evolution of these cases suggests that neuroimaging studies that include the spine should be performed in cases of childhood "unexplained hydrocephalus".

Abstract
Three cases of congenital dermal sinus are presented--2 female and 1 male. Frontal, thoracic, and lumbosacral congenital dermal sinuses were explored. All patients presented with skin findings, but no neurologic deficits. The case with frontal localization was associated with a corpus callosum lipoma and dermoid tumor, and the patient presented with recurrent meningitis. The case with sacral localization was associated with an epidermoid tumor. Morphogenetic, clinical, and radiologic aspects of these cases are discussed. The midline should be carefully examined whenever a child suffers from meningitis. Dermal sinus tracts should be excised prophylactically.

Abstract
This 2-month-old child presented with paraplegia. The authors observed a dermal sinus with purulent discharge in the lumbosacral area. Magnetic resonance (MR) imaging of the spine revealed an intramedullary enhancing cavity spanning C-1 to the conus medullaris. Intraoperatively the dermal sinus was seen to infiltrate the lower end of the conus medullaris, and it also communicated directly with the central canal. The L2-5 laminae were removed, and a myelotomy was undertaken on the conus medullaris. A No. 8 French pediatric feeding tube was passed into the abscess cavity and advanced rostrally to the level of C-1. Aspiration was applied via the feeding tube to drain the intramedullary abscess of the spinal cord (IASC). Postoperatively, a 6-week course of intravenous cloxacillin was instituted. Follow-up MR imaging revealed complete resolution of abscess. When the patient was 26 months of age, examination showed complete neurological recovery. The authors describe what, to their knowledge, is the first case of a holocord IASC treated successfully by the aforementioned technique, and review of the related literature.

Abstract
A rare case of sacrococcygeal dermal sinus suffering from relapsing meningitis is presented. In addition, deference of clinical figure and pathology between sacrococcygeal region and other regions are discussed. A 10 -month-old boy was suffering from relapsing meningitis. Spinal MRI was performed to find occult spinal dysraphism because he had a pit on his hip. The MRI revealed sacrococcygeal dermal sinus. He received surgical resection of dermal sinus based on this findings. Interestingly, different from other dermal sinuses, the dermal sinus runs to caudal direction, and was fused filum terminale with dermoid cyst. This interesting pathological feature of sacrococcygeal dermal sinus seems to come from developmental difference between sacrococcygeal dermal sinus and the other dermal sinuses. Only sacrococcygeal dermal sinus is related with caudal cell mass on its pathogenesis. Because filum terminale is also developed from caudal cell mass, sacrococcygeal dermal sinus seems to be related with filum terminale. Most important differential diagnosis is coccygeal pit that is found in 1 -4% of newborn baby. The clinical feature and pathology got from our case must be very helpful to distinguish sacrococcygeal dermal sinus from coccygeal pit.

Abstract
OBJECTIVE The congenital dermal sinus (CDS) is a benign tumor-like entity that has unique anatomical and clinical features. We retrospectively examined our data to determine factors associated with adverse outcomes for cranial-based dermal sinuses. METHODS We retrospectively examined our data obtained from patients presenting between 1975 and 2002. Sixty-seven patients with a CDS were found. Of these, 20 cases of a cranial CDS were identified, 15 of which had evidence of an intradural component. RESULTS Surgical treatment of congenital dermal sinuses was accompanied with, in general, excellent results. Poor outcomes were most strongly associated with delays in diagnosis. The most common complications were infection at the surgical site (five patients) and hydrocephalus necessitating ventriculoperitoneal shunt placement (two patients). Permanent neurological deficits were rare. CONCLUSION Cranial CDSs are unusual lesions found in children. A majority of these lesions may penetrate the dura and lead to significant complications if not promptly identified and treated in an appropriate and timely fashion.

Abstract
OBJECTIVE We report a case of prenatal diagnosis and postpartum management of a subcutaneous tumor without intracranial communication. METHODS An occipital tumor without intracranial communication was found on ultrasound scan in the 21st week of pregnancy. Using MRI, the diagnosis was confirmed. Subcutaneous localization of the tumor was verified and communication with intracranial space excluded. RESULTS The newborn was delivered spontaneously at term and underwent a successful surgical procedure 5 months postpartum. CONCLUSION The prenatal diagnosis allowed differentiation between a communicating neural tube defect with poor prognosis, and a manageable extracranial subcutaneous tumor. The precise diagnosis of uncomplicated dermal sinus was possible only after the histological evaluation of the tumor confirmed occipital dermal sinus associated with hemangioma.

Abstract
INTRODUCTION Spinal extradural arachnoid cysts are an uncommon cause of neural compression in children. Even more uncommon is the association of such cysts with spina bifida occulta. MATERIAL Two girls, 12 and 8-years-old, presented with left leg pain, deteriorating gait, clinical signs of left L5 and S1 root compression, without bladder or bowel symptoms. The first patient had left foot drop. The second patient had muscle wasting and smaller left foot with pes cavus. Radiographs showed spina bifida occulta of S1 in both. MRI revealed an extradural cyst at the S1 level, indenting the thecal sac and the L5 and S1 roots. At operation in both patients a large arachnoid cyst arising from a small dural defect in the axilla of the left S1 root was compressing and displacing it and the dural sac. It was removed and the defect was repaired. The first patient improved with complete recovery of the foot drop. An MRI at 12 months showed no cyst recurrence. The second patient made good recovery initially, but at 10 months developed recurrent symptoms. An MRI scan showed recurrence of the cyst with root compression. On repeat exploration a different dural defect was identified in a more anterior position and was repaired. DISCUSSION The coexistence of extradural arachnoid cyst and corresponding bifid spinal segment has not been described previously. It raises the suspicion that the dural defect giving rise to the arachnoid cyst may be due to segmental dural dysgenesis in the context of the dysrhaphic neuroectodermal malformation.

Abstract
Intracranial dermoid cyst is a rare entity accounting for 0.1-0.7% of all intracranial tumors. The most common location is in the posterior fossa, at or near the midline. We present 2 pediatric cases with dermal sinus. The first case presented with clinical signs of increased intracranial pressure and cerebellar symptoms. CT scan showed a large and regular midline posterior fossa cyst without contrast enhancement. The second case was revealed by recurrent meningitis. CT scan showed a midline vermis low-density mass with capsular contrast enhancement. Dermal sinus was found in 2 cases. Complete surgical removal was performed followed, in a second operation, by ventriculoperitoneal shunt in 2 cases. There was no postoperative complication in our patients. The aim of this study is to discuss the clinical aspects of dermoid cyst, especially in cases with dermal sinus, and to review the therapeutic strategies in case of associated hydrocephalus.

Abstract
We report a case of a neonate with complex spinal dysraphism and associated anomalies of the axial skeleton. Based on the clinical presentation and radiographic findings, and recent advances in the understanding of human embryogenesis, we formulate a hypothesis that such a presentation is the result of failure of normal gastrulation. A 1-day-old male neonate presented with multiple right-sided anomalies, including hypoplastic right face and decreased movement of the right upper extremity. Radiographic studies demonstrated absent right cervical hemivertebrae, right cervical lipomyelomeningocele, and cervical diplomyelia with right hemicord terminating in a blind pouch. Anterior and posterior cervical and thoracic fusion with instrumentation was performed at the age of 3 years, and on follow-up the patient had improvement in right upper extremity strength. Complex spinal dysraphism is a pathological process that occurs during different stages in human development. We describe a case involving a rare lateral lipomyelomeningocele in the cervical-thoracic area.
