A case of atypical caudate lobe hemangioma mimicking hepatocellular carcinoma: CT and angiographic manifestations.
We report a case of caudate lobe hemangioma with an atypical CT enhancement pattern. In the present case, hemangioma exhibited a very subtle discontinuous peripheral rim enhancement at the post-enhanced arterial phase, and the peripheral enhanced zone had a moderately increased enhancement degree and with widened enhancement thickness during the portal-phase and delayed-phase. The slow enhancement rate for this caudate lobe hemangioma was due to sluggish perfusion by the small feeding arteries of caudate lobe branches as demonstrated by angiography.
