Hemangiopericytoma of the sciatic notch presenting as sciatica in a young healthy man: case report.
A case of hemangiopericytoma of the sciatic notch presenting with sciatica in a healthy 33-year-old man is presented. Tumors of the sciatic notch are exceedingly rare, and few data pertaining to the entity are found in the literature. A few series have been published on neurogenic tumors of the sciatic nerve, and one series of hemangiopericytomas mentions a case in which the sciatic nerve in the thigh is involved with tumor. To our knowledge, this is the first case in the literature detailing a hemangiopericytoma spanning the sciatic notch. Hemangiopericytomas are well known to neurosurgeons as durally based lesions and have been categorized as a subtype of meningioma. However, hemangiopericytomas are vascular sarcomas that most commonly occur in the pelvis and thigh. A brief discussion of the symptoms of sciatic notch lesions and hemangiopericytomas is included.
