This publication presents a clinical case of a patient in order to draw attention to the importance of dynamic monitoring of the patient, monitoring of examination data, including multispiral computed tomography of the chest organs in dynamics, a joint coordinated approach to the diagnosis of the disease according to a single algorithm of the occupational pathologist and general practitioners. The analysis of sanitary and hygienic characteristics, the results of the examination of related specialists in order to exclude a common somatic pathology similar in X-ray data, as well as dynamic monitoring will make it possible to correctly verify the diagnosis and start appropriate treatment in a timely manner.
