  Keywords: stroke, acute ischemic stroke, stroke imaging, CT stroke diagnosis, middle cerebral artery stroke, anterior circulation infarction, stroke pathophysiology, stroke treatment Abstract Stroke remains one of the most devastating neurological disorders worldwide and represents a leading cause of mortality and long-term disability. Early diagnosis using neuroimaging—especially computed tomography (CT)—plays a critical role in determining therapeutic strategies and improving clinical outcomes. This article presents an in-depth expert analysis of acute ischemic stroke in the anterior circulation , integrating clinical history, imaging interpretation, pathophysiology, epidemiology, diagnosis, treatment, and prognosis. The discussion is based on the clinical imaging case described in the attached material and supported by the latest evidence from internationally recognized literature such as the World Health Organization , American Heart Association , and the National Institu...

  Keywords: Cerebral air embolism, arterial air emboli, cerebral infarction, cerebral air embolism CT, cerebral air embolism MRI, hyperbaric oxygen therapy, paradoxical embolism, patent foramen ovale, brain infarction imaging, neuroradiology Introduction Cerebral infarction from arterial air emboli , also known as cerebral air embolism (CAE) , represents a rare but devastating neurological emergency that can lead to severe ischemic brain injury, seizures, coma, and death. Despite its rarity, CAE has gained increasing recognition due to the widespread use of invasive vascular procedures, hemodialysis, central venous catheterization, cardiothoracic surgery, and neurointerventional techniques. The growing complexity of modern medicine has paradoxically increased the incidence of iatrogenic arterial air embolism, making early diagnosis and management essential for neurologists, radiologists, intensivists, and emergency physicians. From a pathophysiological perspective, arterial air em...
