Littoral cell angioma. Axial T2wi FSE with fat suppression (a), pre- (b) and postcontrast axial 3D-GRE T1wi with fat suppression at the venous phase (c) and after 10 minutes of contrast injection (d). A hypointense nodular lesion is depicted on T2wi (arrow, (a)), with areas of magnetic susceptibility artifact, and hypovascular nodules that show subtle peripheral enhancement with progressive slow centripetal accumulation of contrast (arrow, (d)). This mass was thought to represent a sclerosed splenic hemangioma. This heterogeneous splenic appearance is also possible with angiosarcoma and in cases of splenic hemangiomatosis. Note the anteriorly adjacent splenic cyst.
