Multiple Subcutaneous 18F-FDG-avid Granulomas Due to Enoxaparin Injection.

A 67-year-old female patient with metastatic gastric adenocarcinoma was referred to 18fluorine-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) for restaging. PET/CT revealed liver metastasis and the patient received six-cycles of chemotherapy. On control 18F-FDG PET/CT the liver lesion disappeared but newly formed multiple foci of increased uptake in the subcutaneous adipose tissues of the abdominal wall were detected. The uptake was related to nodular lesions resulting from an idiosyncratic reaction to enoxaparin and from local trauma through repeated injections. ©Copyright 2022 by Turkish Society of Nuclear Medicine, Molecular Imaging and Radionuclide Therapy published by Galenos Yayınevi.
