Hepatic hemangiomas are benign liver tumors, and most of them progress asymptomatically. We report a case of hepatic hemangioma considered the cause of fever. A 53-year-old woman had a fever of 40°C for about 3 months without infection. Hepatic hemangiomas with internal bleeding of 10 cm in size on liver S8/7 and S3/2 were observed. These were resected laparoscopically for diagnostic treatment. She was afebrile after the operation. The pathological diagnosis was hematoma inside cavernous hemangioma. It should be noted that a bleeding hepatic hemangioma may cause fever of unknown origin and be indicated for resection.
