Primary spinal primitive neuroectodermal tumors (PNETs) are uncommon malignancies that are increasingly reported in the literature. Spinal PNETs, like their cranial counterparts, are aggressive tumors and patients with these tumors typically have short survival times despite maximal surgery, chemotherapy, and radiation. Because no standard management guidelines exist for treating these tumors, ...

BACKGROUND: Tumours form an integral part of disease process affecting the CNS and constitute a major part of all intracranial space occupying lesions. AIM: To study the histological findings of CNS tumors and to classify them according to WHO classification. MATERIALS AND METHODS: This is a five year study in which all the specimens of tumors of brain and spinal cord received in the department...

Spinal cord tumours account for about 15% of central nervous system neoplasms. Intramedullary tumours arise within the substance of the spinal cord, whereas extramedullary tumours are extrinsic to the cord. About two thirds of spinal cord tumors in adults are extramedullary in location, among which nerve sheath tumors, meningiomas and Filum terminale ependymomas account for the most. Metastatic...

Introduction: Germ cell tumors account for 3.5 % of pediatric and yolk sac are the most common pure malignant germ in children. Testis ovary sites involvement children older than 2 years. Case Presentation: A 20-month-old boy with a complaint limping was described this case report. Abdominal ultrasonography showed 52 × 50 mm solid abdominal mass. pelvic computed tomography scans left paraspinal...

Introduction: Thermal ablation by microwave (MWA) has proven efficacy in treatment of primary and metastatic cancers. Soft tissue tumors could be ablated completely using MWA. However, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. Case presentation: A 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of ...

Extramedullary intradural spinal tumors are rare. Less than 15% of all central nervous system (CNS) tumors are spinal. Ninety percent of these patients are older than 20 years. Most of spinal tumors are extradural (50-55%) whereas 40-45% are intradural. Furthermore, 5% are intramedullary and 40% are extramedullary. Most common are Schwannomas (29%), followed by meningiomas (25%) and gliomas (22...

OBJECTIVE To compare the age distribution and characteristic MR imaging findings of ependymoma for each typical location within the neuraxis. MATERIALS AND METHODS During a recent eleven-year period, MR images of 61 patients with histologically proven ependymomas were obtained and retrospectively reviewed in terms of incidence, peak age, location, size, signal intensity, the presence or absen...
