Patient: 64 year old male |
History: 6 weeks of severe left lower leg pain |
Image Size:[small][as-submitted]

Findings: Increased radiotracer uptake on all 3 phases of bone scan within the left proximal tibia. The scintigraphic appearance of the proximal tibia is suggestive of Paget's disease, though osteomyelitis and neoplasm could have a similar apperance. Radiographs of the proximal tibia show a non-specific lytic lesion. Classic radiographic findings of cortical thickening and coarse trabeculation are not seen. MRI shows abnormal bone marrow signal within the proximal tibia with an associated surrounding soft tissue mass. Abnormal enhancement is seen both in the bone marrow and the soft tissue mass. |
DDx: Paget's disease, osteomyelitis, neoplasm (primary bone tumor, metastasis, lymphoma) |
Diagnosis: Diffuse large B cell lymphoma (biopsy-proven) |
