Abstract

Metastatic calcification is defined as ectopic calcification of soft tissues in patients with a systemic mineral imbalance, and dystrophic calcification or heterotopic ossification is distinct from that disease. The authors encountered a metastatic calcification of the finger in a patient with chronic renal failure, the lesion disappeared spontaneously during the observation period. We report on a case of metastatic calcification of the finger with a review of the literature.

Figure

• 

  Figure 1 Plane antero-posterior (A) and lateral (B) radiographs show soft tissue calcium deposition in both the lateral and volar aspect of the second middle and distal phalanges.

• 

  Figure 2 T2 weighted sagittal magnetic resonance image shows amorphous calcium deposition with diffuse soft tissue swelling in the volar aspect of the second finger.

• 

  Figure 3 Whole body bone scan images (A, B) show increased radiotracer accumulation in the middle and distal phalanges of the left second finger, ulnar head and right hip joint. Uptake in the ulnar head (B) seems to be an ulnar impaction syndrome and the uptake in the right hip joint (A) seems to be a postoperative change.

• 

  Figure 4 Plane antero-posterior (A) and lateral (B) radiographs show spontaneous resorption of calcium deposition after nine-month follow-up.
