Cavernous hepatic hemangiomas are benign liver tumors and present as incidental findings on sonographic examinations, but little is known concerning their natural course. Therefore, we performed a clinical and imaging follow-up of 64 cases of cavernous hepatic hemangioma in 50 patients during an average 18.8 month period. One case presented a symptom of slightly right upper quadrant pain and two cases showed thrombocytopenia. In one of the thrombocytopenia cases, cavernous hepatic hemangioma was resected because of Kasabach-Merrit syndrome. No case increased in size during follow-up, but one case decreased and disappeared. These results suggested that prolonged clinical and imaging follow-up of cavernous hepatic hemangiomas may be needed.
