Abstract

Chest radiography indicated a well-defined rounded mass at the left lung hilum in a 77-year-old former smoker. Chest computed tomography revealed a longitudinal saccular enlargement of the left pulmonary artery with surrounding soft tissue opacity. Resection of the left lower lobe with segment 1 + 2c was carried out to completely remove the dilated pulmonary artery. The resected specimen revealed obvious dilatation of the interlobar pulmonary artery and its branches. A small yellowish well-demarcated myxoid tumor was contained in this lesion, which was diagnosed as a primary pulmonary artery intramural leiomyosarcoma.
