Calcification of soft tissue frequently occurs in patients undergoing hemodialysis for chronic renal failure and involves the arteries, eyes, periarticular regions, lungs, heart, abdominal viscera, subcutaneous tissues, and skin. In this report, two such patients are described who presented with apparent pulmonary nodules on their chest roentgenograms obtained on admission. By the use of tomograms and apical lordotic views, both proved to have extrapulmonary calcific deposits in the subcutaneous tissues overlying the upper pulmonary zones. The tendency for these collections to undergo progression, regression, or pseudocavitation is illustrated. Definitive radiographic localization of lesions projecting over the pulmonary fields in patients undergoing hemodialysis is emphasized because of the significantly increased incidence of infection (including tuberculosis), septic embolism, and carcinoma.
软组织钙化在慢性肾衰竭接受血液透析的患者中经常出现，累及动脉、眼睛、关节周围区域、肺、心脏、腹部脏器、皮下组织和皮肤。在本报告中，描述了两名此类患者，他们入院时胸部X线片显示有明显的肺结节。通过体层摄影和后前位胸片，证实两人在上肺区上方的皮下组织中有肺外钙化沉积。文中说明了这些沉积物有进展、消退或假性空洞形成的倾向。强调了对血液透析患者肺部区域出现的病变进行明确的放射学定位，因为感染（包括结核病）、脓毒性栓塞和癌症的发生率显著增加。
