title: Diffuse Hepatic Hemangiomatosis in the Adult without Extra-hepatic Involvement: An Extremely Rare Occurrence.
abstract: We present a case of a pathologically proven multinodular diffuse hepatic hemangiomatosis (DHH) with no extra-hepatic involvement in a 68-year-old male. Cavernous hemangioma is the most common hepatic tumor. However, DHH, which is characterized by extensive replacement of liver parenchyma with hemangiomatous lesions, has been rarely reported in adults. The etiology and clinical course are not completely understood because of its rareness, although the diagnosis might be suggested by the magnetic resonance imaging findings.
