Preoperative diagnosis of benign hepatic hamartoma by correlation radioisotopic and angiographic studies.

The case of a 12 year old girl with a hamartoma of the liver is reported. A preoperative liver scan showed accumulation of technetium-99m sulfur colloid in the tumor with isotopic and contrast arteriography demonstration of a hypervascular intrahepatic mass. Although these diagnostic findings are not pathognomonic of hamartoma, they are indicative of a benign lesion within the liver.
