Images of a 73-year-old Asian man who underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography for metastasis evaluation for malignant lymphoma. a and b Maximum-intensity projection images obtained by 18F-fluorodeoxyglucose positron emission tomography/computed tomography shows focal hypermetabolic lesions (maximum standardized uptake values 1.92 [chest wall], 2.56 [olecranon of left ulna], 2.88 [left third metacarpal bone], and 12.15 [left testis]; red arrows), which were proven to be malignant lymphoma by histological and radiological examinations. c Follow-up 18F-fluorodeoxyglucose positron emission tomography/computed tomography after chemotherapy shows disappeared hypermetabolic lesions in the above-described sites
