[Inflammatory myofibroblastic tumor of the lung: problems in differential diagnosis].

Inflammatory myofibroblastic tumor is a neoplasm of intermediate biological potential, a marked inflammatory component, and characteristic genetic changes. Once it was identified as an independent nosological entity from a rather heterogeneous group of inflammatory pseudotumors. This paper describes a case of inflammatory myofibroblastic tumor of the chest in a child, by discussing the criteria for differential diagnosis in the use of up-to-date radiology techniques. When thoracic neoplasms are detected, it is necessary to determine their site and the most likely origin organ as exactly as possible and to assess the X-ray pattern of the pathological process. By applying the state-of-the-art radiodiagnostic techniques, the clarification of the pattern of the disease makes it possible to choose an optimal treatment policy and a surgical procedure and scope, to avoid anesthesia overload, and to decrease the probability of resurgery. Our observation is to demonstrate possible problems in the diagnosis of inflammatory myofibroblastic tumor of the lung in childhood and to recall again the algorithm of radiological approaches to detecting mediastinal and lung masses.
