               Introduction

               Background on Takayasu’s Arteritis
               Takayasu’s Arteritis (TA) is a chronic panarteritis condition of the large arteries, such as the
               aorta, common carotid, and subclavian,
               which causes arterial wall thickening,
               stenotic changes, and potentially the
               formation of aneurysmal and thrombus
               development (Johnston, Lock, & Gompels,
               2002; Mavrogeni, Dimitroulas,
               Chatziioannou, & Kitas, 2013). TA is also
               called Martorell syndrome, occlusive
               thromboarteriopathy, pulseless disease,
               idiopathic aortitis, aortic arch syndrome,
               aortoarteritis, and stenosing aortitis
               (Johnston et al., 2002; Russo & Katsicas,
               2018). TA is more prevalent in women in
               their reproductive age between ten to        Figure 1. Geographical mapping of TA: Higher incidence of TA

               Background on Patient

               Princess Peach is a 25-year-old female situated in Kyoto Japan who has a history of
               hypertension. At a recent checkup appointment, she presents with a long-standing fever of
               37.5°C; a left brachial blood pressure (bp) of 90/60mmHg with a right bp of 140/80mmHg
               representing a difference between the two arms greater than 10mmHg; and upon auscultation
               bruits are heard over the aorta and carotids. She informs her doctor that she has been
               experiencing headaches, general malaise, nausea, and recently lost seven kg causing Peach’s new
               weight to be 50kg. Blood work showed mild anemia with an elevated erythrocyte sedimentation
               rate (ESR).  Peach’s broad range of symptoms present similar to TA’s nonspecific clinical
               presentations including being asymptomatic at first, to developing malaise, weight loss, fever,
               night sweats, and weaker pulses in the upper extremities (Johnston et al., 2002; Mavrogeni et al.,
               2013).


               Diagnostic Findings

               Based on Peach’s nonspecific clinical presentations, she is sent to diagnostic imaging including
               digital subtraction angiography (DSA), computed tomography angiography (CTA), nuclear
               medicine (PET), high-resolution ultrasound (US), and magnetic resonance angiography (MRA).
