Lipiodol retention within hepatic cavernous hemangioma.

Intraarterial injection of Lipiodol has been recommended to differentiate hepatocellular carcinoma from benign lesions such as cavernous hemangioma, because uptake and prolonged retention of the contrast medium is a characteristic of the malignant tumors. In two cases of cavernous hemangioma of the liver in which we injected Lipiodol, uptake and retention up to 3 months was demonstrated. We conclude that the intraarterial injection of Lipiodol may not be reliable in differentiating hepatocellular carcinoma from cavernous hemangioma of the liver. [ABSTRACT FROM AUTHOR]
