Abstract
CAVERNOUS hemangiomas of the liver are sufficiently common that they will often be incidentally discovered during hepatic imaging by ultrasound, computed tomography, or radiocolloid scintigraphy. The differentiation of these benign tumors from primary or metastatic hepatic malignancy is mandatory, but often it is not possible on the study in which the lesion was originally detected. There are several routes by which to arrive at the correct diagnosis, but the optimum study or sequence of studies may elude the physician caring for the patient. Knowledge of the imaging options, and the strengths and weaknesses of each of these options, will facilitate a rapid diagnosis and ensure proper treatment, with maximum patient safety and minimum expenditure of resources. RADIOLOGICAL METHODS Nuclear Medicine The routine liver-spleen scan utilizing technetium 99m sulfur colloid offers little help in differentiating cavernous hemangiomas from other space-occupying lesions of the liver. In addition, its sensitivity in detecting lesions
