Nodular pulmonary ossifications in differential diagnosis of solitary pulmonary nodules.

摘要

When considering a solitary pulmonary nodule or coin lesion, the differential diagnosis comprises a lot of different disease entities. Although uncommon, in specific patient grotips, pulmonary ossifications should also be considered. We report two patients in whom the diagnosis of pulmonary ossification was confirmed pathologically and present a general discussion on this subject.First, in a 68-yr-old patient with a history of hypercholesterol-aemia and hypertension, a suspicious right mediastinal shadow was incidentally found on chest radiography after insertion of a central venous line. Personal history revealed poliomyelitis, retinal detachment and, especially, ventricular flutter for which he was resuscitated. Afterwards, he suffered from memory disturbances and even a frontal syndrome. A cardioverter-defibrillator was implanted. Chest radiography revealed a nodular aspect in the right lung hilum, which was not seen on a previous radiogram. Subsequent chest computed tomography (CT) demonstrated enlarged lymph nodes but no apparent ossifications.
