Using the diagnostic web viewer, we have provided images that assist in telling our clinical story. Areas of significance are indicated below.
Soft tissues: Fiducial markers have been placed along the radial aspect of the thumb. A subcutaneous soft tissue mass is identified just proximal to the interphalangeal joint space of the thumb. Dimensions of the lesion are 6 x 5 x 14mm. It is low in signal on T1 and high in signal on T2. It is most consistent with a ganglion possibly arising from the interphalangeal joint space. The remaining soft tissues of the thumb and hand are within normal limits. Visualized portions of the carpal tunnel are within normal limits.
Bone marrow: No AVN or fractures are identified. The osseous structures are intact.
14 x 6 x 5mm mass along the radial aspect of the thumb most consistent with a ganglion likely arising from the interphalangeal joint space of the thumb. Epidermoid less likely.
