The syndrome of painful ophthalmoplegia. A case with intraorbital mass and hypervascularity.

A patient diagnosed as having Tolosa-Hunt syndrome on clinical grounds was found by arteriography to have an intraorbital mass with hypervascularity. To our knowledge, this radiologic finding has not previously been reported in either Tolosa-Hunt syndrome or in the syndrome of orbital pseudotumor, and supports the proposition that these two conditions are anatomical variants of the same pathological process.
