[X-ray diagnosis of peripheral chondromatous hamartomas of the lungs].

A roentgenomorphographic picture was compared with gross specimens of the lungs in 104 operated on patients with peripheral harmatochondromas. Eighty three patients were followed-up roentgenologically for 2-18 years. The resultant three variants of an x-ray picture of hamartochondromas were revealed. CT investigation showed a benign process in a majority of patients, hamartochondrosarcoma was diagnosed in 36.5 per cent. Shadow size enlargement, calcifications and their increase are not signs of malignancy.
