Abstract

<p>A 16-year-old male experienced pain in the right shoulder one month ago. Since a chest radiograph did not clearly show abnormal findings, he underwent symptomatic treatment. However, during the rehabilitation, he suddenly turned pale and had a cold sweat. A chest radiograph and CT examination revealed right hemothorax. Furthermore, chest CT revealed a highly absorbent structure in the chest cavity near the right 7th rib, and the surrounding thoracic adipose tissue was thickened. The next day, because anemia progressed and pleural effusion increased, we performed thoracoscopic surgery. Osteophytes were found protruding into the thoracic cavity from the right 7th rib. The facing diaphragm surface was uneven and irregular, causing bleeding from that site. The osteophyte was removed, and the pathological diagnosis of the specimen suggested osteochondroma.</p>
