title: FDG PET/CT Findings in Primary Diffuse Large B-cell Lymphoma, Leg Type.
abstract: A 64-year-old man presented with complaints of worsening left foot pain and swelling. MRI showed a soft tissue mass overlying the dorsolateral aspect of the left foot. Following a 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT), the left foot mass was biopsied and pathology indicated a diagnosis of primary diffuse large B-cell lymphoma, leg type (PDLBCL, LT). Review of the PET/CT images demonstrated hypermetabolic activity associated with the left foot mass, multiple subcutaneous nodules/nodes, sclerotic osseous lesions in the lower extremities, and left external iliac/left inguinal lymphadenopathy. At the moment, the patient is undergoing chemotherapy.
