Diagnosis: Cavernous hemangioma

Full history:

This 56-year old man was recently diagnosed with prostate carcinoma and on a preoperative CT study was noted to have at least two hypodense lesions in the liver, which showed some peripheral nodular enhancement suggestive of hemangiomas. The hepatic blood pool study was obtained for confirmation.


Tc-99m in vitro labeled red blood cells


SPECT images were obtained one hour post injection. These demonstrate two foci of increased blood pool activity; the smaller one in the left lateral lobe of the liver and a second larger lobular one in the posterior right lobe of the liver. These corresponded in location to the hypodense lesions seen on the CT study.


Hepatic blood pool scintigraphy has a very high predictive value for cavernous hemangiomas. Only a few false-positive cases have been reported. SPECT imaging improves contrast resolution and should be used when lesions are less than 3 cm in diameter or when there are multiple lesions.
