Abstract
The purpose of this report is to underscore one previously unreported hepatic parenchymal lesion detected during evaluation of occult lower gastrointestinal hemorrhage. In more than 90% of the patients harboring the lesion, the individual remains asymptomatic, requires no intervention, and closed biopsy is contraindicated: hepatic cavernous hemangioma. Whereas the list is expanding of normal and abnormal structures which can interfere with the interpretation of scintigraphic gastrointestinal bleeding studies accomplished with 99mTc-labeled erythrocytes, it is absolutely necessary to demonstrate intestinal transit of the activity, in order to discount detected activity in either non-hemorrhagic lesions or normal structures as the nidus of suspected bleeding.
