Abstract:
A 66-year-old woman with a known history of diffuse large B-cell lymphoma presented with left lower limb swelling following recent long-distance air travel. Ultrasound Doppler showed no evidence of deep vein thrombosis. In view of her medical history, an F-FDG PET/CT was ordered that found a soft tissue mass following the course of the femoral neurovascular bundle along the anteromedial aspect of the left thigh down to the popliteal fossa and the lateral calf muscle. This was confirmed to be tumor recurrence.
