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

[摘要] 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.
