Female, 52 years old. Finger pain, swelling, bruising. There is soft tissue swelling dorsal to the third metacarpal head. We see no underlying fracture or malalignment. There is bone formation along the volar aspect of the middle phalanx. We suspect that this simply represents prominence at the site of insertion of the flexor digitorum superficialis. However, if this correlates to the site of the patient's pain, MRI can be considered to evaluate for the possibility of Nora's lesion (bizarre parosteal osteochondromatous proliferation).
Soft tissue swelling and other findings as described above. We see no fracture.
