On examination, there was local swelling, redness, and tenderness. The movement of the index finger MCP joint was painful.
Patient Data
There is periarticular soft tissue calcification near dorsal-radial side of the index finger metacarpophalangeal joint. Osteopenia is present. There is no bone injury.
There is a well-defined periarticular soft tissue calcification involving the dorsal-radial side of the index finger metacarpophalangeal joint. It measures about 10 x 7 x 5 mm. Adjacent soft tissues reveal inflammation and hypervascularity. The index finger metacarpophalangeal joint shows mild effusion.
Case Discussion
An elderly lady presented with an acutely painful index finger metacarpophalangeal joint. There was no associated trauma/fever. Radiographs show juxta-articular soft-tissue calcification. Ultrasound shows local inflammation due to a leak from calcium deposit. History, radiographs, and ultrasound favor acute calcific periarthritis.
The patient responded to the conservative treatment.
