title: Giant intercostal aneurysm complicated by Stanford type B acute aortic dissection in patients with type 1 neurofibromatosis.
abstract: Vascular involvement is rare in neurofibromatosis type 1 (NF1). It is often missed because it is usually asymptomatic. We report a case of a 42 years old male with neurofibromatosis type 1 who presented with left back discomfort. CT angiography revealed a massive 42 mm aneurysm of left 11th intercostal artery. After a discussion between radiologists and cardiothoracic surgeons, endovascular coil embolization was chosen to treat this patient. Percutaneous aneurysm embolization was successfully performed. However, the procedure was complicated by Stanford type B acute aortic dissection. Stanford type B acute aortic dissection was medically managed and patient remained well after discharge. Fragile vascular nature was thought to be one of the causes of this unreported complication.
