Fibromuscular dysplasia presenting with bronchial artery involvement

Fibromuscular dysplasia (FMD) is a rare noninflammatory, nonatherosclerotic vascular disorder associated with arterial beading, aneurysms, dissections, and rarely rupture, most commonly affecting the renal and carotid arteries in middle-aged women. We report a 75-year-old man with hypertension and hyperlipidemia found on computed tomography angiography to have celiac artery dissection, bilateral renal artery irregularities, and right bronchial artery aneurysms with a beading appearance consistent with FMD. The patient was managed conservatively with blood pressure control, antithrombotic therapy, and imaging surveillance. This case highlights the extremely rare involvement of bronchial artery in patients with FMD.
