The growth of hepatic cavernous hemangiomas in two patients who underwent resection was documented by computed tomography and subsequent volumetry. In patient I, 40-year-old woman, the tumor increased from 4.6 to 7.2 cm in diameter and from 58 to 244 ml in volume during a 3.5 year period. In patient 2,67-year-old man, the tumor increased from 7.5 to 17 cm in diameter and from 123 to 1434 ml in volume over 10.5 years. The major indication of the operations was the growth of the hemangiomas. This quantified documentation of growing hepatic hemangiomas, a novelty in the literature, suggested the need of long-term follow-up of hepatic hemangioma.
