Female, 52 years old. Palpable nodule at right IP joint. The soft tissues of the first finger unremarkable, without abnormal areas of enhancement, solid mass lesions, or discrete fluid collections. There is diffusely increased signal on T2-weighted images within the marrow of the visualized portion of the first metacarpal, without focal lesion, abnormal T1 signal, or abnormal enhancement. Otherwise, the visualized osseous structures, tendons, and ligaments appear intact.
1.No focal abnormality within the soft tissues of the right first finger to account for the patient's palpable abnormality. Correlation with plain radiographs may be useful for further evaluation.2.Diffusely increased T2 signal without abnormal enhancement within the visualized first metacarpal bone marrow is of unclear etiology, but may reflect a contusion.
