title: Recurrent giant cell tumor of foot detected by F18-FDG PET/CT.
abstract: Detection of recurrence of tumors with conventional imaging like computed tomography (CT) and magnetic resonance imaging (MRI) can be difficult because of distorted anatomy and implants in situ. Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT has been shown to be very useful in detection of recurrent tumors with higher accuracy than conventional imaging method. Giant cell tumors of foot though rare have high recurrence potential after initial curative treatment. However, currently there is no literature addressing the role of F-18 FDG PET/CT in evaluation of these tumors. We report a case of post excisional recurrent giant cell tumor of foot diagnosed on F-18 FDG PET/CT. In addition, to detection of recurrence F-18 FDG PET/CT also aided in accurate management of the patient.
