Primary rhabdomyosarcoma of the tentorium with peculiar angiographic findings.
Primary intracranial rhabdomyosarcoma is extremely rare, only nine cases have been reported in the world literature. To differentiate it from medullomyoblastoma, rhabdomyosarcoma should be devoid of neuroblastic elements. A case of rhabdomyosarcoma of the tentorial region in a 17-year-old boy is reported. Carotid angiograms demonstrated a peculiar neovascularity. Multiple cytologic preparations of CSF repeatedly contained rhabdomyosarcoma cells and CSF dissemination in the spinal subarachnoid space was documented at autopsy. The literature is reviewed.
