Subclavian artery aneurysms (SAAs) are rare and even more uncommon in patients with fibromuscular dysplasia (FMD). A 20-year-old man with a past medical history of moyamoya disease presented with an abnormal mass shadow in the apex of the right lung on chest X-ray. Based on computed tomography imaging, a diagnosis of right SAA was established, and an excision of the aneurysm was performed. Because the left vertebral artery is dominant, the proximal and distal right subclavian artery and right vertebral artery were clamped. Then, the aneurysm was excised, and resection anastomosis was performed. Histological findings revealed FMD. The postsurgical course has been uneventful after 2 years. Among treatment modalities, open surgery would be the first choice for SAAs with FMD, despite the current era of endovascular surgeries.
