He did not have symptoms or a history to suggest other diseases or trauma except hypertension. Arteriography revealed a rupture of the right 10th and 11th intercostal artery, and transcatheter arterial embolisation was successfully done. The patient was discharged without any sequelae. To our knowledge, this is the second report in the literature documenting spontaneous intercostal artery rupture without associated illness or injury. Through comparison with the first reported case, we discuss the cause, the vulnerable site, and the treatment of spontaneous intercostal bleeding.
