Infrequent delayed controlateral remote cerebellar hemorrhage after supratentorial craniotomy in adult patient: a case report.

Remote cerebellar hemorrhage as a rare complication of supratentorial surgery was already first described in the 1970s by Yasargil. Its incidence ranges from 0.2% to 0.

Vertebral solitary bone plasmacytoma in a young adult with Trisomy 21: A case report.

Solitary bone plasmacytoma (SBP) are rare lesions, accounting for less than 5% of all plasma cell proliferations. We describe a case of a 21-year-old female with Trisomy 21 presenting with cauda equina compression from an SBP. Solitary bone plasmacytoma (SBP) is a rare primary bone tumor.

Ewing's sarcoma of the cranial vault: a case report.

Ewing's sarcoma is a malignant tumor that mainly affects young patients. It represents 10% of primary malignant tumors of the bone and 3% of malignant tumors of the child. Cranial localization is extremely rare representing less than 1% of all the localizations.

[Cerebral gliosarcoma: clinico-pathologic study of 8 cases].

Background: Gliosarcomas are biphasic neoplasms composed of a glioblastoma admixed to a sarcomatous component with different lines of differentiation. Histogenesis of these tumors is still discussed.

Aim: Our objective is to specify clinical and pathological characteristics of this rare neoplasm and to discuss its histogenesis.

Gliosarcoma with osteosarcomatous features: a short illustrated review.

Introduction: Gliosarcoma is a rare, malignant, biphasic brain tumor formed by both glioblastoma and sarcomatous components. Various lines of differentiation are described in the latter component, but most commonly fibrosarcomatous and pleomorphic sarcoma are present. Osteosarcomatous features are exceedingly rare.
