Hepatic cavernous hemangioma with atypical peripheral rim activity on hepatic blood pool imaging.

Hemangioma is the most common benign liver tumor. Hepatic blood pool imaging is an effective technique with a specificity approaching 100%. Typically, hemangiomas are completely filled on hepatic blood pool imaging. However, incomplete fill-in can be seen in larger hemangiomas complicated with thrombosis, fibrosis, or bleeding. We report a hepatic cavernous hemangioma with atypical peripheral rim activity.
