title: Acute coccydynia related to precoccygeal calcific tendinitis.
abstract: Symptomatic deposits of calcium hydroxyapatite have been reported in various sites other than the shoulders or hips. Sudden-onset coccydynia can lead to the discovery of calcific deposition in the precoccygeal region. We present the case of precoccygeal calcific tendinitis in a patient with acute coccydynia.
