چکیده
Inflammatory myofibroblastic tumor (IMT) is a mesenchymal neoplasm of intermediate biological potential and could occur at any anatomical site from the central nervous system to gastrointestinal tract. IMT of the lung is a relatively uncommon condition, with a reported incidence between 0.04 1.2% of all tumors of the lung. A 26-year woman was admitted to our hospital with complaint of irritating cough for the past six months. Chest computed tomography scan demonstrated a 6.8 cm x 6.9 cm, densely calcified mass in the right lower lobe neighboring the mediastinum. The tumor was radically resected via lobectomy and partial excision of right hemidiaphragm and pericardium, and the stump of tumor within inferior vena cava was electrocauterized. Histological examination combined with immunohistochemical study discovered an inflammatory myofibroblastic tumor with osseous component.
