[Use of computerized tomography in the differential diagnosis of spherical and cavitary formations in the lungs of children and adolescents].

Computed tomography (CT) of the chest organs was used in a comprehensive examination of 19 children and adolescents with spherical and cavitary formations in their lungs and mediastinum. Comparative analysis of the results obtained by means of routine X-ray examination and CT of the chest organs of the children and adolescents with spherical and cavitary formations in their lungs revealed that CT greatly improved their differential diagnosis. CT provides valuable additional data and is an optimum X-ray method for differential diagnosis of spherical and cavitary formations in children and adolescents.
