Computed tomography of a rapidly growing hepatic hemangioma.

A rapidly growing hepatic hemangioma was observed in a 40-year-old woman during the follow-up period of 1.5 years. Contrast enhanced CT and angiography performed 3.5 years prior to and at the time of operation were compatible with hemangioma, but the diameter of the mass changed from 4.6 to 7.2 cm during this period. The pathogenetic reason for this rapid growth was unclear at the time of resection.
