title: Primary intracranial sarcomas: radiological diagnosis with emphasis on arteriography.
abstract: The radiological manifestations of primary intracranial sarcomas may be non-specific and they vary widely according to their histological variations. Reticulum cell sarcomas, however, can be included in the differential diagnosis with a high degree of reliability when one observes a hypovascular mass with arterial encasement and deep medullary veins. Tumor vessels and tumor stains supplied by dilated feeding arteries suggest the possibility of a sarcoma of the brain or of the meninges in infants. Nine reticulum cell sarcomas, four undifferentiated sarcomas, and one fibrosarcoma are presented here with their radiological manifestations, especially on angiography.
