[Pulmonary schwannoma with hypervascularity; report of a case]

A 54-year-old female was admitted to our hospital with a mass shadow in the right pulmonary hilum. The chest computed tomography (CT) scan revealed a well-circumscribed mass in the lower lobe of the right lung. Bronchoscopic examination showed a submucosal tumor in the right basal bronchus which bled easily, and the angiogram showed a tumor with hypervascularity. The tumor was suspected to be a sclerosing hemangioma or malignant tumor. A right basal segmentectomy was performed, and the pathological diagnosis was that of schwannoma. During the 8 year follow-up period, she exhibited no evidence of recurrence.
