Abstract
INTRODUCTION Dorsal spurs in Type I split cord malformations (SCM-I) are infrequent findings. The pathogenesis of the same is debatable. The objective of this study is to analyze our experience with SCM-I patients having dorsal bony spurs. METHODOLOGY Retrospective analysis of SCM patients operated from 2010 to 2017 was performed. Their demographic profile, clinic-radiological features, operative findings, and outcome following surgery were recorded. RESULTS Twenty-four cases of Type I SCM harboring dorsal bony spurs were identified with mean age of 4.96 years. The commonest split site was lumbar, documented in 62.5%. Scoliosis was observed in 58.3%. Pre-operative neurological deficits were seen in 66.6% cases with asymmetric weakness of limbs seen in 16.6%. There was no new neurological deficit observed post-operatively. CONCLUSIONS This is the largest series of dorsal spurs occurring in SCM, reported in literature so far. Meticulous pre-operative evaluation and imaging are important to identify dorsal spurs for appropriate management and good clinical outcome. Differentiating dorsal spur from ventral spur is important as it has a bearing on surgical approach.

Abstract
BACKGROUND Aplasia cutis congenita (ACC) is characterized by the absence of a portion of skin in a localized or widespread area at birth. It manifests usually as a solitary defect on the scalp, but sometimes may occur on the face, trunk, or limbs. ACC is most often a benign isolated defect, but can be associated with other physical anomalies or malformation syndromes. A few cases have been reported in which patients with split cord malformation (SCM) have presented with ACC. METHODS Two patients with SCM are reported. RESULTS Both patients presented with ACC and abnormal hair growth on their backs. Type II SCM was detected in the first patient and Type I SCM in the second. No surgical treatment was performed because the patients were neurologically intact. CONCLUSIONS ACC may seldom manifest as a skin marker of SCM. Our patients are unique examples of SCM presenting with ACC, but not requiring surgery. It is important to recognize ACC as a cutaneous sign of SCM, and to refer these patients to radiologic evaluation as soon as possible.

Abstract
Split cord malformations (SCMs) are rare congenital anomalies of the spine which are usually diagnosed and treated in early childhood. Asymptomatic patient can appear in adult life without diagnosis. Cutaneous signs are often the initial marker of congenital spine abnormalities, especially SCMs. Although numerous cutaneous lesions have been described that may occur with SCMs including abnormal hair growth, hemangiomas, telengiectasias, pigmentation anomalies, subcutaneous mass lesions, and dermal sinus tracts, there is no study demonstrating a correlation between skin lesions and the type of SCM. We reported the cutaneous findings of 14 adult patients who were investigated clinically and radiologically with a diagnosis of SCM. Hypertrichosis was the most common cutaneous lesion (79%) and faun tail was observed among six (55%) of the 11 patients who had hypertrichosis. The SCM was type I in all of the patients with faun tail. Silky down was observed among 5 (45%) patients as a solitary skin lesion or associated with dysplastic skin or capillary hemangioma. A statistically significant correlation between the skin markers and the type of SCM was found, and this correlation can help physicians weigh their diagnostic considerations in SCM.

Abstract
OBJECTIVE To evaluate the clinical profile, associated anomalies and surgical outcome of children with meningomyelocele (MMC)/lipomeningomyelocele. METHODS Out of a total of 181 cases of spinal dysraphism treated at our Institute between 1996 and 2004, 102 (56.35%) cases of MMC/lipomeningomyelocele were analyzed retrospectively and prospectively. The clinical profile and radiological findings of these children were recorded. Craniospinal MRI was the essential investigation and was done as a management protocol at our Institute for these children. Eighty-two out of 102 (80.3%) cases had pure MMC/lipomeningomyelocele and 20/102 (19.6%) had associated split cord malformation (SCM; complex spina bifida). All these children underwent surgery for their primary and associated malformations as indicated. They were clinically assessed over a mean follow-up period of 3.6 years ranging from 1.5 months to 8 years. No urodynamic or evoked potential studies were done to assess the sphincteric outcome following surgery. RESULTS Forty-six (45.1%) of children with MMC had other associated tethering lesions, including the presence of SCM. Craniospinal axis screening remained an important tool to understand the associated tethering lesions and malformations. Only 58.8% of children had hydrocephalus; thus the incidence was much lower compared with reports from the western literature (80-96%). 63.3% of children with overt hydrocephalus required shunt surgery prior to the definitive surgery; however, 23.3% of cases required a shunt after the MMC has been closed. Improvement in clinical profile following microneurosurgery was observed in 42.8% of cases with motor involvement, 46.8% of cases with sensory dysfunction and 39.5% of cases with sphincteric involvement. Motor improvement was seen in 43.6% of cases of pure MMC/lipomeningomyelocele as compared to only 40.0% of cases of complex spina bifida. Sensory improvement was also better in pure MMC/lipomeningomyelocele group being seen in 48.0% of cases as compared to only 42.9% of cases of complex spina bifida. CONCLUSION Presence of SCM with MMC is referred to as complex spina bifida and is seen in a significant proportion (19.6%) of all cases of MMC. Thorough assessment of the craniospinal imaging needs to be done to look for the presence of multiple tethering lesions which could be present in the same case. Not all children with spinal dysraphism with hydrocephalus required shunt surgery or CSF diversion but a constant and vigilant follow up could avoid it in 13.3% of cases. Improvement in motor and sensory dysfunction was better in the pure MMC/lipomeningomyelocele group than in the complex spina bifida group. Improvement in sphincteric dysfunction, although seen in significant cases, was less compared with improvement in motor and sensory dysfunction. This probably represents a lack of definitive objective criteria for urodynamic improvement and a lack of proper rehabilitation. Electromyographic studies and uroflowmetry are required to asses the true sphincteric outcome following surgery.

Abstract
OBJECTIVE To see the difference in clinical profiles, radiological findings and surgical outcome of the group 1 split cord malformation and meningomyelocele (SCM with MMC) from group 2 (SCM without MMC). METHODS 46 patients of SCM were selected from a total of 138 cases of spinal dysraphism. They were divided into two groups, based on presence or absence of MMC. Group I (SCM with MMC) n =19 patients and Group II (SCM without MMC) n=27 patients. A detail clinical evaluation and MR screening of whole spine of all cases was performed. All patients underwent surgical detethering of cord. After an average follow-up of 1.7 years, the operative results were clinically assessed and statistical significance was calculated. RESULTS Male to female ratio was 1:09. Mean age of presentation was 3.6 years. Cutaneous markers like tuft of hair, cutaneous haemangioma, etc, had a higher incidence in group II in comparison to group I (50% vs 10.5%). The incidence of motor deficits was significant in group I in comparison to group II (63% vs 40%). The incidences of sensory loss, trophic ulcers, sphincteric dysfunction and muscle atrophy were relatively more common in group I patients, while neuro-orthopedic deformities such as congenital telepes equinovarus (CTEV), scoliosis and limb shortening were more frequent (67%) in group II children as compared to group I (53%). Type I SCM has higher incidence in group I children. Low lying conus were found in 47% patient of group I, while in group II it was noticed in 69%. The associated cranial anomalies like hydrocephalus, ACM and syrinx, were slightly higher in group I patients. At surgery, dysgenetic nerve roots, neural placode, arachnoid bands and atrophic cord were seen mainly in group I. Postoperative complications like, CSF leak, pseudomeningocele and meningitis were more commonly encountered in group I patients. The patients of group II showed better operative outcome compared to group I cases. CONCLUSION Incidence of SCM with MMC amount to 41% of total SCM cases. Progressive neurological deficit was higher in this group (SCM with MMC) in comparison to the group harboring SCM without MMC. In view of a significant association of SCM in MMC cases, associated with other craniospinal anomalies, a thorough screening of neuraxis (by MRI) is recommended to treat all treatable anomalies simultaneously for desired outcome.

Abstract
Intraspinal dermoid tumor and diastematomyelia is a rare combination of pathologies and only eight cases were priorly published. We report a new case in an adult with clinical presentation of progressive paresis and sensitive deficit in the lower limbs, associated with a thoraco-lombar kyphoscoliosis. The diagnosis based on the CT scan and MR images was confirmed at surgery. Pathophysiologic and clinical aspects as well as the radiological characteristics of these pathologies are dicussed and the importance of the early diagnosis is emphasized.

Abstract
We reviewed the results for forty-three patients who had a diastematomyelia. All of the patients had been skeletally immature when the diagnosis was made, the mean age being six years (range, birth to thirteen years), and were skeletally mature by the time that they were evaluated by us. When they were first seen at our institution, twenty-four patients (56 per cent) had a cutaneous lesion, such as hairy patch, dimple, hemangioma, subcutaneous mass, or teratoma at or near the level of the diastematomyelia; thirty-four patients (79 per cent) had congenital scoliosis; and forty-two patients (98 per cent) had at least one associated musculoskeletal anomaly, such as spinal dysraphism, asymmetry of the lower extremities, club foot, or a cavus foot. In twenty-seven patients (63 per cent), the diastematomyelia was located in the lumbar spine. Thirty-six patients had eighty-four neurological manifestations. Resection of the spur was performed in thirty-three patients at a mean age of seven years (range, three months to seventeen years). Twenty-two patients who had a resection had no change in neurological condition, nine patients had improvement, and one patient had one symptom improve and another symptom worsen after the operation. We believe that resection of the spur should be performed in patients who have progressive neurological manifestations. Patients who do not have progressive neurological manifestations should be observed; if progression is noted, a resection should then be performed.

Abstract
Much confusion still exists concerning the pathological definitions and clinical significance of double spinal cord malformations. Traditional terms used to describe the two main forms of these rare malformations, diastematomyelia and diplomyelia, add to the confusion by their inconsistent usage, ambiguities, and implications of their dissimilar embryogenesis. Based on the detailed radiographic and surgical findings of 39 cases of double cord malformations and the autopsy data on two other cases, this study endorses a new classification for double cord malformations and proposes a unified theory of embryogenesis for all their variant forms and features. The new classification recommends the term split cord malformation (SCM) for all double spinal cords. A Type I SCM consists of two hemicords, each contained within its own dural tube and separated by a dura-sheathed rigid osseocartilaginous median septum. A Type II SCM consists of two hemicords housed in a single dural tube separated by a nonrigid, fibrous median septum. These two essential features necessary for typing, the state of the dural tube and the nature of the median septum, do not ever overlap between the two main forms and can always be demonstrated by imaging studies so that accurate preoperative typing is always possible. All other associated structures in SCM such as paramedian nerve roots, myelomeningoceles manqué, and centromedian vascular structures frequently do overlap between types and are not reliable typing criteria. The unified theory of embryogenesis proposes that all variant types of SCMs have a common embryogenetic mechanism. Basic to this mechanism is the formation of adhesions between ecto- and endoderm, leading to an accessory neurenteric canal around which condenses an endomesenchymal tract that bisects the developing notochord and causes formation of two hemineural plates. The altered state of the emerging split neural tube and the subsequent ontogenetic fates of the constituent components of the endomesenchymal tract ultimately determine the configuration and orientation of the hemicords, the nature of the median septum, the coexistence of various vascular, lipomatous, neural, and fibrous oddities within the median cleft, the high association with open myelodysplastic and cutaneous lesions, and the seemingly unlikely relationship with fore and midgut anomalies. The multiple facets of this theory are presented in increasing complexity against the background of known embryological facts and theories; the validity of each facet is tested by comparing structures and phenomena predicted by the facet with actual radiographic, surgical, and histopathological findings of these 41 cases of SCM.

Abstract
Thirty-nine patients with split cord malformations (SCM) were studied in detail with respect to their clinical, radiographic, and surgical findings as well as their outcome data. Eight patients were adults and 31 patients were children. According to the classification endorsed by Part I of the SCM study, 19 patients had Type I SCM (6 adults and 13 children), 18 patients had Type II SCM (2 adults and 16 children), and 2 patients had composite SCM with both lesion types situated in tandem. Six SCMs were cervical, 2 were thoracic, and 31 were in the lumbar region. All 8 adults had pain and progressive sensorimotor deficits at diagnosis. Only 16 of the 31 children had symptoms, and among these, 14 had progressive sensorimotor deficits, but only 6 had pain. The difference in the clinical picture between adults and children is similar to that described in the tethered cord syndrome, except for left-right functional discrepancy, which was prominent in 8 children with SCM but rarely seen in tethered cord syndrome due to other causes. Cutaneous manifestations of either occult or open dysraphic states were present in all but 3 patients; hypertrichosis was by far the best predictor of an underlying SCM, being found in 56% in the series. Neurological deterioration in SCM was independent of the lesion type: the Type I:Type II ratio for symptomatic progression was 13:11. It was also independent of the location of the lesion: 67% of patients with cervical SCMs had symptomatic progression versus 64% of patients with thoracolumbar lesions. High-resolution, thin cut, axial computed tomographic myelography using bone algorithms was more sensitive than magnetic resonance imaging in defining the anatomical details of the SCM. Radiographic classifications of the SCM, using the nature of the median septum and the number of dural tubes as criteria, was always possible without ambiguity. However, whereas every Type I bone septum was identified preoperatively, only 5 Type II fibrous septa were revealed by preoperative imaging, even though a fibrous septum and/or other fibroneurovascular bands were found tethering the hemicords in every Type II case at surgery. Complete imaging studies also showed that all lumbar SCMs had low-lying coni and at least one additional tethering lesion besides the split cords, whereas only 1 of 7 cervical and high thoracic SCMs had a low conus and a second tethering lesion. The surgical goal for SCM was release of the tethered hemicords by eliminating the bone spurs, dural sleeves, fibrous septa, or any fibroneurovascular bands (myelomeningoceles manqué) that might be transfixing the split cord. Type I cases were technically more difficult and had a slightly higher surgical morbidity than Type II cases, especially if an oblique bone septum had asymmetrically divided the cord into one larger hemicord and one smaller, hence, very delicate, hemicord.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A family with congenital localized hypertrichosis transmitted in an autosomal dominant pattern is presented. The excessive hair growth was localized to the cervical region and was associated with underlying kyphoscoliosis. No additional cutaneous or skeletal abnormalities were identified. To our knowledge these are the first cases of familial congenital cervical hypertrichosis associated with underlying kyphoscoliosis reported in the literature.
