Myxopapillary Ependymoma-a Case Report of Rare Multicentric Subtype and Literature Review.

Background: Myxopapillary ependymoma is a rare type of primary spinal tumor, it is distinctly a slow-growing tumor that originates in the conus medullaris, cauda equina, or film terminals and is rarely identified as a multicentric type. Myxopapillary ependymoma has a unique histological characteristic and is associated with a generally better prognosis. Objective: We present a case of a rare multicentric myxopapillary ependymoma. Case presentation: A 28-year-old male with 1-year history of low back pain and 3 months of radiating pain to left lower limb with perianal anesthesia. Magnetic resonance imaging (MRI) exhibited a large intradural intramedullary lesion from the level of the conus medullaris extending to the filum terminals at the level of T12 to L3 with smaller multiple enhancing lesions seen opposite to L4 and L5 level as well as within the exiting nerve roots, at the left side of L1/L2 and L2/L3 and right side of L3/L4 and L5/S1 level. The patient underwent surgical resection with significant improvement in symptoms and no tumor progression on follow up MRI scan. Conclusion: We hereby present a case of multicentric myxopapillary ependymoma with a literature review of the previous reported cases. We believe that our study will make a significant contribution to the literature and will be of interest to the readership regarding of the rarity of multicentric Myxopapillary ependymoma and it will help in decision making for the proper surgical Intervention on these kinds of cases.

Adult Desmoplastic Medulloblastoma.

Medulloblastoma is more common in young age and rare in adult age. Some characteristics that characterize medulloblastoma in adults compared with children: Lateral cerebellar location, heterogeneous signal intensity on magnetic resonance imaging, desmoplastic histological variant and more favorable prognosis. Preoperative diagnosis is important for correct management of these patients. However, because of the low incidence of medulloblastoma in adults, preoperative diagnosis still challenging and prognostic factors and best treatment options are still controversial. We report a case of a 31-year-old male patient who presented with a rare case of posterior fossa medulloblastoma.
