Abstract
Because of its tumor origin from nerve sheath cells (the Schwann cells), the pathogenesis of an extraordinary rare intramedullary schwannoma, which should not have any Schwann's cells in nature, is controversial and still in debate. We report a case of a 63-year-old man diagnosed with a cervical cord intramedullary schwannoma with an interesting intraoperative finding that could support one of the theories on its genesis.

Abstract
Intramedullary schwannomas (IMS) represent exceptional rare pathologies. They commonly present as solitary lesions; only five cases of multiple IMS have been described so far. Here, we report the sixth case of a woman with multiple IMS. Additionally, we performed the first complete systematic review of the literature for all cases reporting IMS. We performed a systematic review of the literature in PubMed, EMBASE and Cochrane Central Register of Controlled (CENTRAL) to retrieve all relevant studies and case reports on IMS. In a second step, we analysed all reported studies with respect to additional cases, which were not identified through the database search. Studies published in other languages than English were included. One hundred nineteen studies including 165 reported cases were included. In only five cases, the patients harboured more than one IMS. Gender ratio showed a ratio of nearly 3:2 (male:female); mean age of disease presentation was 40.2 years; 11 patients suffered from neurofibromatosis (NF) type 1 or 2 (6.6%). IMS are rare. Our first systematic review on this pathology revealed 166 cases, including the here reported case of multiple IMS. Our review offers a basis for further investigation on this disease.

Abstract
BACKGROUND Spinal schwannoma is a common benign tumor. However, the high recurrence rate and incidence of surgical complications are unsolved problems. OBJECTIVE To propose a morphological classification of spinal schwannoma based on tumor-membrane relationships to increase the gross total resection (GTR) rate and to decrease the incidence of surgical complications. METHODS Histological techniques were used to study 7 adult cadavers. Following picrosirius staining, the membranes around the nerve root were observed under a microscope. Data from 101 patients with spinal schwannoma were also collected for clinical analysis. RESULTS The sleeve around the spinal nerve root consisted of dura and arachnoid tissues. The space between them gradually narrowed and fused at the proximal pole of the nerve root ganglion. Spinal schwannomas were divided into 4 types based on membranous structure: intrapial (type I), subarachnoidal (type II), intra- and extradural (type III), and extradural growth (type IV). Types II and III were further subdivided into 2 subtypes. GTR was achieved in all patients (100%), with no tumor recurrence during follow-up. Overall functional status significantly improved postoperatively. A total of 59 patients (92%) showed improvement or significant improvement postoperatively. There was no difference in surgical outcomes among the tumor classifications (P = .618). No intraoperative vertebral artery injuries or postoperative cerebrospinal fluid fistula occurred. CONCLUSION Spinal schwannoma classification based on a membranous hierarchy provides an intuitive platform for preoperative planning and intraoperative safety. This classification scheme may help surgeons better define surgical goals and anticipate or even avoid complications from resection.

Abstract
RATIONALE Schwannomas grow slowly, originating from the Schwann cells of the nerve sheath. Schwannomas of cranial origin have the highest incidence, followed by intraspinal schwannomas. However, paravertebral schwannoma is rare, and to our knowledge, giant paravertebral schwannomas near the lumbar nerve roots with bone destruction are extremely rare. PATIENT CONCERNS A 47-year-old Chinese woman complained of lower back soreness and a sensation of a bulging lumbar disc with no obvious cause for the past 3 years. DIAGNOSIS Lumbar magnetic resonance imaging showed a large mass with uneven density, 17 × 12 × 15 cm in size, located to the right of the 4th lumbar with obvious bony destruction. Histopathology and immunohistochemistry confirmed that this mass was a benign schwannoma. INTERVENTIONS Complete resection of the tumor (measuring about 17 × 12 × 15 cm in size) and vertebral reconstruction using internal fixation were performed. OUTCOMES The patient was discharged without complications after surgery. The 3-year follow-up revealed that the patient recovered well with no evidence of recurrence. LESSONS Here, we emphasize the importance of careful radiological examination and reflect on the difficulty of tumor resection. Furthermore, understanding the treatment and diagnosis of lumbar paravertebral schwannoma is critical for plastic surgeons and radiologists when encountering similar cases.

Abstract
BACKGROUND Intramedullary schwannomas of the spinal cord are extremely rare. Most previous studies are case reports, which have found that intramedullary schwannomas could be homogeneous or asymmetrically enhanced with gadolinium. However, intramedullary schwannomas with minimal enhancement have not been reported. CASE DESCRIPTION This article describes a 34-year-old patient who presented with nonradiative neck pain, progressive weakness of the left limbs, and sensory deficit of both lower extremities. Preoperative examinations such as magnetic resonance imaging (MRI) were performed, and the patient underwent surgical treatment. MRI showed that the lesion presented unsharp enhancement with gadolinium on T1-weighted images. Histopathologic findings were consistent with the diagnosis of schwannoma. CONCLUSIONS We report a case of intramedullary schwannoma that presented inconspicuous enhancement with gadolinium. MRI is useful but cannot be used to differentiate schwannomas from other intramedullary spinal tumours. Surgical resection is the most vital factor for the treatment of intramedullary schwannoma.

Abstract
Cervical intramedullary schwannomas are extraordinarily rare. Gross total resection is the best therapeutic option for these types of tumors. Although rare, intramedullary schwannomas should be considered as a differential diagnosis of intramedullary lesions since a good prognosis can be guaranteed to the majority of these patients. We present a case of a cervical intramedullary schwannoma surgically treated in a 19-year-old male patient who initially presented with motor neuron disease.

Abstract
OBJECTIVE To identify the magnetic resonance imaging features of intramedullary spinal schwannomas. METHODS Clinical and magnetic resonance imaging findings of 8 patients with pathologically confirmed intramedullary schwannomas were reviewed. RESULTS There were 6 male and 2 female patients (mean age, 49 years). Tumors were located in the cervical cord (2), the thoracic cord (5), and the cervicothoracic cord (1). Most were in the dorsolateral spinal cord and limited to one side. Expansion of the cord was observed. The majority were hypointense on T1-weighted images and hypo-hyperintense on T2-weighted images. Peritumoral edema was easily found. Gadolinium enhancement was obviously. No recurrence was seen during the follow-up period. CONCLUSIONS A tumor located in the dorsolateral spinal cord, causing expansion of the cord, with hypointense areas on T2-weighted and obviously enhancement, should arise suspicion of an intramedullary schwannoma.

Abstract
Synchronous spinal intramedullary ependymal cysts and intramedullary schwannomas are rare. To the best of our knowledge, the present study is the first report of a case of intramedullary schwannoma coexisting with an ependymal cyst. A 35-year-old male presented with lower back pain and weakness in the left leg. Magnetic resonance imaging identified an intramedullary cystic-solid lesion at the thoracolumbar junction of T11-L2; based on the clinical presentation and radiological features, a pre-operative diagnosis of ependymoma was formed. Subsequently, the patient underwent a T11-12 laminectomy via a posterior approach, with intraoperative monitoring of somatosensory and motor-evoked potentials, achieving a gross total resection of the tumor with a well-demarcated dissection plane. Post-operative histopathological examination demonstrated a schwannoma coexisting with the ependymal cyst, and the neurological status of the patient markedly improved compared with the pre-operatively observed neurological deficit.

Abstract
OBJECT Intramedullary schwannomas are exceedingly rare. Most previous studies are case reports with an associated literature review. The aim of this study was to discuss the clinical features and the outcomes of microsurgery for these rare lesions. METHODS The authors retrospectively reviewed the data of twenty patients with intramedullary schwannomas. All patients had performed preoperative and postoperative magnetic resonance imaging (MRI) and underwent microsurgery. The diagnosis of intramedullary schwannomas was based on radiological and pathological criteria. Modified McCormick classification was applied to assess neurological function. RESULTS There were 15 males and five females with a mean age of 44.7 years. Ten tumors were located in the cervical cord, five in the thoracic cord, two in the cervicothoracic cord, two in the thoracolumbar cord and one in the conus medullaris. Patients presented with nonspecific symptoms and the mean duration of symptoms was 37.4 months. Intraoperatively, the tumor was connected to the dorsal rootlet in four cases. Gross total resection (GTR) of the tumor with a well-demarcated dissection plane was achieved in 16 cases, and subtotal resection (STR) was achieved in four cases. No patients received postoperative radiotherapy. During a mean follow-up period of 67.9 months, no recurrence or regrowth of the residual tumors was observed on MRI. Ninety percent of patients experienced an improvement in the McCormick grade and 10 % of patients maintained their preoperative status. CONCLUSIONS Intramedullary schwannomas are benign but clinically progressive lesions. The accurate diagnosis depends on pathology. For symptomatic patients, early surgery should be performed before neurological deficits deteriorate. When GTR cannot be achieved, STR of the tumor for decompression is advised. Postoperative radiotherapy is not recommended for these benign tumors. A good clinical outcome after GTR or STR can be expected.

Abstract
Intramedullary schwannoma is often misdiagnosed as other types of malignant tumour prior to surgery due to its atypical imaging appearance and low incidence. In the present study, a case of small intramedullary schwannoma was analysed using clinical and imaging data. Data concerning the surgery and follow-up process of this case were collected. Instead of performing the traditional surgical procedure of cutting the central and posterior rhizotomies of the patient, minimally invasive hemilaminectomy was performed to maintain spinal stability. This procedure was selected since the small mass would be removed completely via minimally invasive hemilaminectomy. Intramedullary schwannoma was confirmed following surgery. The patient recovered well and no recurrence of the tumour was detected during the two-year follow-up period. In conclusion, the treatment strategy for intramedullary schwannoma was determined based on its atypical symptoms and imaging characteristics.

Abstract
BACKGROUND CONTEXT There have been few reports on intramedullary ancient schwannoma. Schwann cells are generally present in the nerve root, not in the spinal cord. Thus, intramedullary schwannomas are rare, and in most cases there is cyst formation without calcification. PURPOSE To report a patient with intramedullary ancient schwannoma at the epiconus together with a review of the previously published cases. STUDY DESIGN Case report. PATIENT A 78-year-old woman. METHODS Retrospective case review. DESCRIPTION OF THE CASE A 78-year-old woman had presented with severe weakness of the lower extremities, increased patellar reflex, and sensory disturbance of the entire lower extremities. Magnetic resonance imaging showed a tumorous mass in the intramedullary region of epiconus at T11-L1, and computed tomography revealed calcification in the tumor. She underwent total resection of the tumor. Histopathological findings were consistent with the diagnosis of ancient schwannoma. After the operation, although lower extremities weakness and sensory disturbance deteriorated transiently, lower leg pain disappeared. At the final follow-up of 10 months after the operation, lower leg pain did not relapse. CONCLUSION We reported a rare case presenting epiconus syndrome due to intramedullary ancient schwannoma, which should be considered for the differential diagnosis of a tumor that shows calcification.
