[Computed tomography at the outpatient stage of differential diagnosis of destructive inflammations and tuberculosis of the lung].
The authors retrospectively analyzed the quality of RCT differentiation of destructive lung lesions at outpatient diagnostic units of multidisciplinary polyclinics. At the first stage, the recognition accuracy rate was not more than 73%, which is attributable to the high macroscopic similarity of bacterial destructive inflammations and specific tuberculous processes. Both conditions were frequently complicated by the addition of fungal invasion that made their differentiation all the more difficult. It has found that during the tense epidemiological situation associated with tuberculosis, there is its explainable, but not always justified hyperdiagnosis. The ratio of false-negative to false-positive tuberculosis results was 1:2. The paper is illustrated by different types of destructive inflammations that mimic tuberculosis and by the trend of some of the types is shown. Emphasis is laid on the neglects and errors that cause diagnostic differences. A half of them is attributable to the objective complexities of its diagnosis; the other (subjective) half is a potential reserve for upgrading the quality of differential diagnosis in phthisiopulmonology.
