  Edited by ScholarGen MediAI Team Executive Answer Takayasu arteritis should be considered when a young patient presents with otherwise unexplained systemic symptoms and dizziness together with multifocal large-vessel abnormalities. In this case, neck CT angiography (CTA) demonstrated bilateral subclavian artery origin occlusion, severe proximal right common carotid artery stenosis, diffuse narrowing of the right internal carotid artery, and approximately 75% stenosis of the left common carotid artery. Concentric arterial wall thickening and collateral reconstitution further support a large-vessel vasculitic process. The key radiologic lesson is that Takayasu arteritis is not simply a stenosis diagnosis: the radiologist must interpret the arterial wall, lesion distribution, occlusion, distal reconstitution, collateral circulation, and potential complications as one vascular system. Why This Case Matters Dizziness is common and has a broad differential diagnosis. Inner-ear disorder...

  An Evidence-Based Radiology Review of Transient Perivascular Inflammation of the Carotid Artery Edited by ScholarGen MediAI Team Featured Snippet: What Is TIPIC Syndrome? Transient perivascular inflammation of the carotid artery (TIPIC) syndrome is an uncommon clinicoradiological condition characterized by acute unilateral neck pain, focal tenderness over the carotid artery, and eccentric inflammatory changes around the carotid bifurcation or distal common carotid artery. Imaging typically demonstrates perivascular soft-tissue infiltration, localized arterial wall thickening, and sometimes mild luminal narrowing. The diagnosis requires exclusion of alternative vascular and nonvascular conditions, particularly carotid artery dissection, vasculitis, and deep neck infection. Most patients improve within approximately two weeks, although recurrence can occur. 1. Introduction: When Unilateral Neck Pain Requires Vascular Imaging Unilateral neck pain is a common clinical complaint, but ...
