This life-threatening condition arises when an intimal tear in the aortic wall allows blood to enter the media, creating a false lumen that may rupture into the pericardial sac, leading to haemopericardium and potentially fatal cardiac tamponade. Rapid recognition and urgent management are crucial. This comprehensive review provides an expert-level synthesis of the pathophysiology, epidemiology, clinical presentation, imaging features, differential diagnosis, diagnostic strategy, treatment, and prognosis of aortic dissection with haemopericardium, grounded in...

A Comprehensive Radiologic Review Based on State-of-the-Art Literature Introduction: Why the Meningo-Ophthalmic Artery Matters The meningo-ophthalmic artery (MOA) is a rare but critically important vascular variant that every radiologist, neurosurgeon, neurologist, and neurointerventionalist must recognize. Although often asymptomatic, failure to identify this artery—particularly during middle meningeal artery (MMA) embolization or skull base interventions—can result in irreversible visual loss . With the widespread use of CT angiography (CTA), MR angiography (MRA), and digital subtraction angiography (DSA) , the detection of subtle external carotid artery (ECA)–internal carotid artery (ICA) anastomoses has increased. Among these, the meningo-ophthalmic artery represents one of the most dangerous “hidden” variants. This column provides a comprehensive, expert-level review of the pathophysiology, epidemiology, clinical presentation, imaging characteristics, differential diagnosis...
