Aortoarteritis: A rare pulmonary-renal disease

ABSTRACT

Takayasu arteritis (TAK) is an autoimmune disease majorly affecting young females. It alters the vascular wall, resulting in stenosis, occlusion, or dilatation. It has no distinct clinical manifestation. Here, we present the case of an 18-year-old girl who presented with generalized tonic-clonic seizure and hypoxia. Blood investigations showed deranged urea and creatinine values. Computed tomography angiography revealed bilateral artery occlusion, decreased kidney size, and pulmonary artery dilatation, confirming generalized vascular disease that caused hypertension and ischemic nephropathy in the patient. Our case represents a rare autoimmune disease, leading to pulmonary hypertension and renal artery stenosis. TAK should be considered as a differential diagnosis in young female patients presenting with pulmonary as well as renal signs and symptoms, especially if there is discrepancy in blood pressure levels in all limbs.
