Splenic Infarction Mimicking a Necrotizing Metastasis of Malignant Melanoma on F-18 FDG PET/CTAhmadzadehfar, Hojjat MD*; Brockmann, Holger MD*; Schmiedel, Alexandra MD†; Biersack, Hans-Jürgen MD*; Ezziddin, Samer MD*Clinical Nuclear Medicine: August 2008 - Volume 33 - Issue 8 - pp 571-572 doi: 10.1097/RLU.0b013e31817dec28 Interesting Image Abstract Author Information A 67-year-old woman with a history of malignant melanoma in the right lower leg for 7 years without any known metastases was hospitalized for evaluation of severe left upper quadrant abdominal pain. Computed tomography of the abdomen revealed a suspected splenic mass. F-18 FDG PET/CT imaging showed a large photopenic area in the same region surrounded by a circular area of high FDG uptake. It could not be definitely differentiated between a splenic infarction and a necrotizing metastasis of malignant melanoma or other malignancies. Subsequent splenectomy revealed an infected splenic infarction. From the Departments of *Nuclear Medicine; and †Department of Radiology, University of Bonn, Bonn, Germany.
