46 cases of cavernous hemangioma of the liver, studied by angiography, are reported. Part of them were studied with echotomography and CT too, and 28 with angiotomography. In author's opinion based on experience, angiographic diagnosis of the lesion is, in presence of typical angiographic patterns, always confirmed, while echotomography and CT are not specific, especially in differential diagnosis with neoplastic malignant, primitive or secondary, hepatic lesions. Diagnostic algorithm needs, in their opinion, an initial echotomographical phase and, in presence of positive pictures for expansive hepatic mass with clinical suspicion for haemangioma, angiography and angiotomography for complete and specific diagnosis.
