A case of hepatic hemangioma is presented in which blood pool imaging by $^{99m}Tc$-HSA provided a definite diagnostic clue. Cavernous hemangiomas are the most common benign tumor of the liver. But the majority of them are asymptomatic and are found incidentally at laparotomy or autopsy. Selective hepatic arteriogrophy has been the most helpful technique for the preoperative diagnosis. Recently radioisotope scan and ultrasonogram proved to be a new, definite and non-invasive diagnostic procedure.
