F-18 fluorodeoxyglucose accumulation in an inflammatory pseudotumor of the spleen

Ann Nucl Med. 2007 Nov;21(9):521-4. doi: 10.1007/s12149-007-0055-6. Epub 2007 Nov 26.


We report on a case with an inflammatory pseudotumor of the spleen, which showed a moderate accumulation of F-18 fluorodeoxyglucose (FDG) in the tumor. F-18 FDG accumulated mainly in the peripheral portion of this tumor that showed abundant hypercellular inflammatory cells histopathologically. Splenic inflammatory pseudotumors should be recognized as F-18 FDG-avid benign tumors of the spleen.
