Case 263: Hemangioma
52 year old man with right upper quadrant pain.
MR: Cavernous Hemangioma
Unenhanced T1w image shows a hypointense focal lesion within segment 7. T2w images with fat saturation show high signal intensity, almost as hyperintense as fluid ("light bulb sign"). Arterial sequence shows discontinous nodular peripheral enhancement of the lesion with gradual centripetal enhancement on portal and equilibrium contrast phases typical for a cavernous hemangioma.
