Introduction : Solitary fibrous tumor (SFT) — a rare mesenchymal tumor of fibroblastic origin. Solitary fibrous tumor is not a tumor of the pleura itself, unlike diffuse mesothelioma. The SFT was first described by E. Wagner in 1870. Non-specific clinical manifestations of solitary fibrous tumor complicate the diagnostic search and significantly expand the differential diagnostic range. Purpose : To demonstrate a rare case of solitary fibrous tumor of the pleura and to show, using a clinical case as an example, the difficulties of its diagnosis. Materials and methods : Multislice computed tomography (MSCT) of the chest organs performed to the patient with complaints of cough and shortness of breath during intense physical activity. Formation was detected with clear contours, a heterogeneous structure, located subpleurally was revealed. Results : The presented observation demonstrates non-specific radiological manifestations of a solitary fibrous tumor and illustrates the importance of correct interpretation of data and choice of diagnostic algorithm.
