[Successful removal of an intrapulmonary aberrant needle under video-assisted thoracoscopic surgery; report of a case].

Intrapulmonary aberrant needles are rare in clinical practice. We report the successful removal of intrapulmonary aberrant needle. A 59-year-old man, though he was asymptomatic, was referred to our department after an abnormal shadow had been detected on a chest X-ray. Chest X-ray and chest computed tomography (CT) showed a foreign body suspected to be a metal artifact in the left upper lobe. It was diagnosed as an intrapulmonary aberrant needle and an operation under video-assisted thoracoscopic surgery was performed. Using perioperative fluoroscopy, we could confirm the location of the needle and remove it successfully. An intrapulmonary aberrant needle should be removed surgically, even if the patient is asymptomatic, due to the development of lung abscess or pyothorax and the risk containing harmful matter to health.
