Juxtacardiac costal osteochondroma presenting as recurrent haemothorax

Abstract

A 21-year-old man presenting with a recurrent spontaneous haemothorax was found to have an osteochondroma arising out of the left 4th rib. This was penetrating the apical part of the heart. Surgical excision was uneventful.

A Novel Cause of Acute Coronary Syndrome Due to Dynamic Extrinsic Coronary Artery Compression by a Rib Exostosis: Multimodality Imaging Diagnosis

“…Cardiac complications from diaphyseal aclasis are extremely rare. Fukai et al 1 and Buchan et al 2 have described hemopericardium secondary to rib exostoses penetrating the pericardium. However, the complication of an acute coronary syndrome resulting from a rib exostosis has never been described to our knowledge.…”

A 5-year-old Boy with a Large Hereditary Multiple Exostoses Lump Grown into Thoracic Cavity

“…8) In the previously reported cases involving chest cavity, they were mostly approached with excellent results via formal thoracotomy or thoracoscopic approaches with resection of either the involved rib segment or the exostosis itself. 4,9,10) The outcome of surgery was satisfied with no significant complications in all these reported patients.…”

Spontaneous hemothorax in hereditary multiple exostosis involving the ribs

“…4 Seventeen cases of hemothorax as a result of costal exostosis have been reported in the English-language literature. [2][3][4][5][6][7][8][9][10][11][12][13][14] The proposed etiological mechanism is shearing of pleura or diaphragm by relatively sharp margins of the intrathoracic costal exostosis. 13 Recently, another etiological mechanism was proposed: focal pleural changes induced by long-standing friction between the intrathoracic exostosis and the visceral pleura due to respiratory motion.…”
