case_images: Additionally, degenerative changes were observed in the interphalangeal and metacarpophalangeal joints, including marginal osteophytes, subchondral sclerosis, and joint space reduction, most prominent in the proximal and distal interphalangeal joints (Figure 1).
case_images: Hand MRI. (A-B) Coronal T1-weighted and sagittal PDFS images showing lipomatous hypertrophy of the subcutaneous tissue of the third finger, predominant on the volar side. Small synovial cysts are present (Fig. 2B) and coincide with anechoic structures on ultrasound (Fig. 2C). (D) Axial T1-weighted image with no significant abnormalities of the median nerve (orange circle) and no space-occupying lesions. Axial T1-weighted images through the metacarpal heads (E) and proximal phalanx (F) show subtle fatty infiltration of the common volar digital nerves (yellow arrow) and proper volar digital nerves (red arrows). PD:proton density. FS:fat-saturated.
