Abstract
A 67-year-old female patient with metastatic gastric adenocarcinoma was referred to (18)fluorine-fluorodeoxyglucose ((18)F-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 (18)F-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.
