title: Hypomagnesemia with chondrocalcinosis.
abstract: Two patients are described with calcium pyrophosphate crystal deposition and hypomagnesemia. There appears to be a meaningful association between the two findings, although the precise mechanism explaining this association is not clear. The identification of chondrocalcinosis on radiographs may be an important clue to the presence of hypomagnesemia.
