title: Tear of plantar fascia and tibiocalcaneal ligament with positive F-18 FDG PET findings.
abstract: Although PET/CT imaging provides the most comprehensive evaluation of cancer, coexisting hypermetabolic benign processes may interfere with the staging of aggressive malignancy such as melanoma and extranodal non-Hodgkin lymphoma. Acute and subacute skeletal injuries have been reported as false-positive PET findings. The authors present additional mimickers of high metabolic malignancy with a case of stage III recurrent melanoma featuring F-18 FDG accumulation at partially torn medial plantar fascia and tibiocalcaneal ligament of the left foot.
