Selective carotid angiography in the diagnosis of fibrous histiocytoma. A case report.

Selective carotid angiography is of value in the diagnosis of an orbital fibrous histiocytoma, an uncommon tumor with a high local recurrence rate and frequent distant metastases. The angiogram shows the physical extent of the tumor and also suggests its general microscopic anatomy. Comparison is made with similar angiographic presentations seen in cerebellar hemangioblastomas, glomus tumors, meningiomas, and hemangiopericytomas.
