title: Carpal tunnel syndrome induced by two types of calcium deposition.
abstract: Two rare cases of carpal tunnel syndrome caused by calcification in the carpal tunnel are reported. One case involved a tumorous calcification consisting of basic calcium phosphate, and the other involved a diffuse calcification consisting of a mixture of calcium pyrophosphate dihydrate and basic calcium phosphate. These cases suggest that the shape of carpal tunnel calcifications is influenced by the nature of calcifying substance itself, i.e., whether it is heterogenous or homogenous.
