摘　　要：BACKGROUND Multiple exostoses generally develop in the first decade of life.They most frequently arise from the distal femur,proximal tibia,fibula,and proximal humerus.Costal exostoses are rare,contributing to 1%-2% of all exostoses in hereditary multiple exostoses(HME).They are usually asymptomatic,but a few cases have resulted in severe thoracic injuries.Pneumothorax caused by costal exostoses is rare,with only 13 previously reported cases.We report a new case of pneumothorax caused by costal exostoses.CASE SUMMARY A 17-year-old male with HME underwent surgery for removal of exostoses around his right knee.Four months following the operation,he felt chest pain when he was playing the trumpet;however,he did not stop playing for a week.He was referred to our hospital with a chief complaint of chest pain.The computed tomography(CT)scan revealed right pneumothorax and multiple exostoses in his right ribs.The CT scan also revealed visceral pleura thickness and damaged lung tissues facing the exostosis of the seventh rib.We diagnosed that exostosis of the seventh rib induced pneumothorax.Costal exostosis resection was performed by video-assisted thoracoscopic surgery(VATS)2 wk after the onset.The patient’s postoperative course was uneventful,and there was no recurrence of pneumothorax for 2 years.CONCLUSION Costal exostoses causing thoracic injuries should be resected regardless of age.VATS must be considered in cases with apparently benign and relatively small exostoses or HME.
