Sclerosing angiomatoid nodular transformation of the spleen is a recently recognized benign vascular lesion, characterized microscopically by multiple angiomatoid nodules embedded within a fibrosclerotic stroma. Although its imaging manifestations have been limited in the radiologic literature, features such as low-level increased fluorodeoxyglucose activity on a positron emission tomographic scan, near-complete blending in with normal splenic parenchyma on a delayed-phase image, and the presence of radiating scarring on a magnetic resonance image may suggest the diagnosis. We report here the computed tomographic, magnetic resonance imaging, and positron emission tomographic findings of sclerosing angiomatoid nodular transformation, along with gross and microscopic pathological correlation.
