title: [Differential diagnosis of protracted purulent destruction-complicated pneumonia in patients with risk factors].
abstract: There is some doubt upon the correct diagnosis in a third (136 (31.5%)/431) of patients (114 males and 22 females) admitted as having a diagnosis of protracted pneumonia. An algorithm of examination of patients with risk factors was developed for the differential diagnosis of different types of protracted pneumonia, including its destructive forms. The algorithm was used in the X-ray pattern of infiltrative changes unresolving within 2-3 weeks during nonspecific therapy. Hemoptysis was observed in 76 (17.6%). Its causes were bleeding granulations in 58 patients and aspirated bronchial foreign bodies in 36. Major diagnostic difficulties were presented by 18 (13.2%) patients out of the 136 patients in whom pulmonary changes were detectable as round foci with destruction. Differential diagnosis ascertained blocked abscesses (n = 6), tuberculomas with decay (n = 5), infiltrative destructive tuberculosis (n = 3), peripheral cancer with decay (n = 2), and bronchiectasis (n = 4).
