Scanographic Features of Takayasu’s Arteritis: A Study of Three Cases

Abstract: Takayasu’s arteritis is a rare vasculitis that primarily affects large arteries. It often presents with systemic symptoms like fever and fatigue. Computed tomography (CT) is a crucial examination for diagnosis and follow-up. The first case concerns a 45-year-old woman suffering from intermittent claudication of the arm. Imaging examinations (Doppler ultrasound and CT) revealed a stenosis (narrowing) of the subclavian and axillary arteries, as well as a thickening of the wall of the ascending aorta. This case illustrates a classic presentation of the disease with peripheral vascular symptoms. The second case, a 27-year-old woman, is more complex. The patient presented with asymmetrical blood pressure, an absent left radial pulse, and neurological symptoms due to a stroke (CVA). Imaging (angio-CT and arteriography) showed severe occlusions of the carotid and subclavian arteries, as well as aneurysms, which confirmed the diagnosis of Takayasu’s arteritis. The patient’s survival depended on collateral circulation. Finally, the third case describes a 28-year-old woman with systemic symptoms (weight loss) and thickening of the walls of the carotid arteries and the thoracic aorta, without significant stenosis. This case highlights the diversity of the disease’s manifestations and the importance of regular follow-up to prevent complications. These three observations illustrate the wide variety of clinical presentations of this disease.
