[Pulmonary calcinosis]

Interstitial pulmonary calcinosis was discovered after finding hypercalcaemia in a man of 56 who had been treated for several months with Hydrochlorthiazide. This was a secondary hyperparathyroidism due to the formation of parathyroid adenomatous cysts. This illness had been quiescent until then and was probably revealed as a result of the hydrochlorthiazide therapy.
