Abstract

A 78-year-old woman who had a history of left deep venous thrombosis was referred to our hospital with a sudden hemoptysis. Thoracic computed tomography showed a solitary pulmonary nodule in the right lower lobe. Based on her medical history of deep venous thrombosis, she was tentatively diagnosed as having pulmonary embolism and successfully treated by inserting an inferior vena cava filter and anticoagulant therapy with warfarin [Please confirm whether previous sentence is correct]. However, the lung nodule on thoracic computed tomography was still depicted four months later. With suspicion of a malignant tumor, including possible lung cancer, a right segmentectomy was performed. Pathological assessment of the resected specimen showed the tumor was derived from the right bronchial wall, but was not ruptured into the intratracheal lumen, as well as coexistence with intraalveolar hemorrhage near the tumor. The lung nodule was diagnosed as bronchial schwannoma. Thus, the origin of the hemoptysis was found to be pulmonary embolism due to deep vein thrombosis, and not by bronchial schwannoma, which was also present in the lung.
