Acute calcific periarthritis in the 22-yr-old patient, who was a professional tour golfe. (A) The oblique view of the left fourth finger on plain radiograph shows 5x3 mm well-defined calcification with triangular shape between distal interphalangeal joints (arrow). (B) Triphasic bone scan shows a hot uptake on the PIP joints of the left fourth finger. (C) CT image demonstrates a small calcified lesion on the PIP joint of the left fourth finger (arrow). (D) The plain radiograph taken 2 weeks later shows absorption of calcification (arrow). (E) One month later the area between the PIP joint of the left fourth finger showed small, residual calcification (arrow). (F) Three months later nearly complete resolution of the calcification was observed (arrow).

On oblique view of the initial plain radiographs (Fig. 1A), a dense calcified lesion with a triangular shape measuring 5x3 mm was found, and this lesion was located around the 4th PIP joint; however, there was no evidence of joint space narrowing or cortical lesion. Three-phasic bone scan showed a hot uptake on the 4th PIP joint (Fig. 1B), and CT demonstrated a triangular calcification at the PIP joint (Fig. 1C). Two weeks later this calcification was gradually absorbed, the symptom was relieved, and the limitation in ROM was improved (Fig. 1D). One month later the area between PIP joint of the left fourth finger showed only a small, residual calcification (Fig. 1E). Final plain radiograms taken three months after presentation revealed nearly complete resolution of the calcification (Fig. 1F).
