An observation from practice is given – surgical treatment of a patient with advanced tuberculosis of a single lung and a pronounced lung displacement. Patient A., 47 years old, after 3 months from the left pneumonectomy for fibrocavernous tuberculosis complained of dyspnea at rest, and dysphagia, underwent CT scan, which showed a pronounced displace ment of a single right lung with tuberculoma to the left. At the first stage of the surgery, the overstretched section of a single lung with tuberculoma was resected, the displaced lung was put back and a hernial orifice was strengthened with a mesh implant. At the second stage, the extrapleural thoracoplasty was made with resection of I–IV ribs from the side of pneumonectomy to reduce the volume of the left hemithorax and prevent relapse of mediastinal hernia. As a result, the patient stopped dyspnea and dysphagia, radiographically a single right lung was visualized in the right hemithorax.
