Bilateral multiple pulmonary sclerosing hemangioma.

We present herein a rare case of bilateral pulmonary sclerosing hemangioma, for which a differential diagnosis was made from metastatic lung tumors. A 32-year-old asymptomatic woman was referred to our hospital for further evaluation of abnormal chest shadows. A chest computed tomogram revealed two round, well-circumscribed masses in both sides of the lungs. Metastatic lung tumors were suspected, however, a primary lesion was not detected by several examinations. Thus, simultaneous video-assisted thoracic surgery for the bilateral tumors was performed. The tumors, measuring 16x13x12 mm in the left lung and 27x24x20 mm in the right lung, were resected, and then pathological examination confirmed the diagnosis of sclerosing hemangioma. Her postoperative course was uneventful and she has been doing well without any sign of recurrence.
