Progressive pulmonary calcification after successful renal transplantation.

In 2005, a 46-year-old woman consulted our department for an evaluation of a chest radiographic abnormality. She had undergone a successful living renal transplantation in 1999 after being treated by dialysis for four years. A chest computed tomographic scan revealed progressive bilateral fluffy, poorly defined small nodules and the bronchoscopic study revealed a unique linear and nodular lesion pattern. Based on the findings of these modalities, we confirmed the diagnosis of metaplastic pulmonary calcification. This is the first report of these bronchoscopic findings and submucosal calcification in a case of metastatic pulmonary calcification.
