[Diagnosis and differential diagnosis of solitary pulmonary coin lesions].

Abstract

In the present analysis, the diagnosis as well as the differential diagnosis of solitary pulmonary coin lesions are discussed. The coin lesions of 361 patients who were at our diagnostic ward from 1968 to 1970 were defined according to Rube [1967]. The investigations are in accordance with the routine examinations and were consciously demonstrated in nonselected patients in order to express the several diagnostic procedures, their field of indication and their efficiency in a balanced ratio. Therefore, the efficacy of the X-ray diagnosis could be proved in a broader range than in a collective of circular foci which would have been chosen exclusively under the aspect of the diagnosis by means of needle biopsy and which would reveal a higher percentage of morphological clarification of the focus.
