A retrospective analysis of 32 patients older than 16 years of age treated at Neurosurgical Department of Hacettepe University within the last 30 years (1959-1988) for cerebellar medulloblastoma was considered. The clinical features, treatment modalities and outcome are discussed. The survival rates for 5 and 10 years were 14% and 7% respectively. The results are compared with that of literature.

ReviewVascular malformations of the central nervous system: a morphological overview.
Vascular malformations of the central nervous system (C. N. S.) are classified by size, location, and morphologic type, distinguishing capillary telangiectasias, cavernous malformations, venous angiomas, arteriovenous malformations (AVMs) including varix of the great vein of Galen, and other vascular malformations (e.g. ⋯ They present as simple AV fistulas, cirsoid angiomas with localized vascular plexuses and large complex convolutions ("juvenile" type). The complications of spinal angiomas include subarachnoid hemorrhage, rare epidural hematoma, hematomyelia, compression lesions of the cord and roots, and ischemic changes causing chronic progressive radiculomyelopathy, previously referred to as Foix-Alajouanine syndrome. Chronic damage to the cord and spinal roots results from pressure effects, thrombosis of the abnormal vessels, disorders of venous drainage, and "steal" phenomena related to the vascular anomalies.
