Tumor in an Adult Case

Inflammatory myofibroblastic tumor (IMT) is a rare neoplasm, which is derived of mesenchymal origin. Here we present an adult case with IMT, the origin of which was considered to be right inferior pulmonary vein. A male patient who was 52 years old, admitted to our outpatient clinic with the complaint of shortness of breath. He had cigarette smoking history for 30 years. On direct posterior anterior X-Ray of the chest, a well-circumscribed mass with calcification in right hilum of the lung was observed. There was a mass which was extending to the inferior inferior pulmonary vein from right hilum of the lung, was measured 70 x 60 mm on computed tomography of the chest. Hamartoma, teratoma and Castleman Disease were among the possible diagnoses. On diagnostic bronchoscopy, signs of pressure from outside to the bronchi of the right middle and lower lobe was observed. Surgical excision is decided and the mass was totally excised through a muscle-sparing thoracotomy. The mass thought to arise from the inferior pulmonary vein on intraoperative inspection and right inferior lobe excision is undertaken by intrapericardial approach. No postoperative complication is encountered. Histological examination of the mass indicated inflammatory myofibroblastic tumor. Main treatment of IMT is surgical excision with negative surgical margin. Here in we present an IMT which is encountered at an unexpected location is excised completely with right lower lobe excision by an intrapericardial approach
