Abstract
We describe a case of a 9-year-old female with a giant pulmonary bulla. She had chest pain, and her chest X-ray film and CT showed a right giant pulmonary bulla. A large bulla in the right lung has been recognized on her chest X ray obtained at 5 years old. The pulmonary arteriogram of 3-dimensional CT demonstrated narrowing of the truncus superior and ascending artery. The giant bulla was originated from the right S3 and was resected under thoracoscopy. The remnant lung was well expanded on the chest X-ray following operation.
