Acute carpal tunnel syndrome secondary to pseudogout: case report.

Acute carpal tunnel syndrome secondary to chondrocalcinosis seems not to have been previously reported. In a 75-year-old woman, with arthropathy and calcification of the triangular fibrocartilage of the wrist, hyperparathyroidism was suspected, but not proven. Hydroxyapatite and calcium pyrophosphate crystals were found together in the pathological specimen. The patient obtained complete relief from sectioning of the transverse carpal ligament.
