Vascular lesions, including aneurysms, are rare but well-documented complications of von Recklinghausen's disease. Although aneurysms associated with this condition are often asymptomatic, rupture can lead to life-threatening events such as hemothorax. We report a 63-year-old male with von Recklinghausen's disease who presented with sudden onset of chest pain. Imaging revealed left-side hemothorax, and contrast-enhanced computed tomography( CT) suggested rupture of the left 10th intercostal artery. Given his hemodynamic stability, percutaneous coil embolization was performed. Angiography revealed two adjacent aneurysms at the origin of the left 10th intercostal artery, both of which were successfully embolized. Postoperative course was uneventful, and the patient was discharged on postoperative day 6. This case highlights the importance of considering vascular complications in von Recklinghausen's disease and supports the efficacy and safety of coil embolization in managing ruptured intercostal artery aneurysms.
