Intracavernous cavernous hemangioma: dynamic CT findings and effectiveness of irradiation--case report.

An intracavernous cavernous hemangioma occurred in a 34-year-old female presenting with amenorrhea and hyperprolactinemia. Computed tomography (CT) showed a homogeneously enhanced mass in the right cavernous sinus. The time-density curve detected by dynamic CT showed significant delayed flow in the lesion. The mass was significantly reduced in size by local irradiation (50 Gy). Dynamic CT may be useful in differentiating cavernous hemangioma, and radiation therapy should be considered for preferred treatment to surgical intervention.
