“…Surgical excision of intramedullary schwannomas differs widely from extramedullary schwannomas. However, total excision may not be possible in all the cases, due to the adherence of the tumor to the surrounding neural tissue, 8 as in our case. Reoperation should be considered in case of recurence.…”

Schwannomas are one of the most common primary spinal tumors representing 30% of all intraspinal lesions. Intramedullary schwannomas constitutes 0.3% of all intraspinal tumors and approximately 1% of spinal cord schwannomas. Majority of the tumors are seen in the cervical (58%), followed by thoracic (32%) and lumbar (10%) regions. Very few are reported at the level of conus medullaris. The important radiologic features of intramedullary schwannoma are predominant extramedullary component, intramedullary spinal tumor with a thickened and enhancing spinal nerve root, absent syrinx, enhancing well with contrast, and sharp margins. The aim of surgery in intramedullary spinal schwannomas is total removal whenever possible. Diagnosing intramedullary schwannoma preoperatively needs high index of suspicion. We are reporting the 10th case of intramedullary schwannoma in the conus region.

“…Although some association of proliferating vessels around the tumour [4,32,35,68,102], tumour connection to a nerve root [4,27,34,43,46,52,58,68,71,76,77,84,89,99,104,107,109,115,123] or chronic disease of the spinal cord could be observed in reported cases [39,100,107], it is still not possible to make a general statement regarding the pathogenesis of IMS. In our case, a tumour connection to the nerve root could be observed in the MRI of the cervical spine.…”

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.

“…To our knowledge, several authors did a literature review of intramedullary schwannomas since We have found that 48 cases were reported since 2005, which brings the total number of cases to 118, including our case. [1][2][3]8,10,11,13,18,19,[23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] The cases reported between 2005 and 2014 are summarized in ►Tables 1 and 2. Lee et al studied 10 cases of intramedullary schwannomas that were diagnosed in their hospital from 1995 to 2010 and they found that 7 of them were in the lumber region and 3 in the cervical regions.…”

Schwannoma is a nerve sheath tumor originating from the Schwann cell. It is benign in nature and it arises from anywhere where Schwann cells can be found. It is rarely found in the parenchyma of the spinal cord. Intramedullary schwannomas (or neurilemmomas) without evidence of neurofibromatosis are rare spinal cord tumors. Intramedullary schwannoma was first reported in 1932 by Penfield. Our patient presented with neck pain, gradually worsening, weakness in the right upper and lower limbs, numbness in both shoulders, and a decrease in the grasping strength of both hands over a 4-year period. A magnetic resonance imaging of the spine showed a heterogeneously enhancing mass in the cervical spinal cord extending from the C2 to T1 levels with associated hemorrhagic changes. Histologically, the tumor was found to be composed of bland spindle cells with blunt-ended and sometimes wavy nuclei admixed with hyalinized vasculature. Surrounding reactive spinal cord parenchyma with frequent Rosenthal fibers was also observed. Focal Verocay bodies were evident, and with immunohistochemistry, there was diffuse and strong positivity for S100, which is confirmatory for the diagnosis of schwannoma. We report a case of cervical intramedullary schwannoma presented with syringobulbia in a young adult. AbstractKeywords ► intramedullary schwannomas ► syrinx ► spinal cord tumor ► cervical Indian
