Recurrent TIA from Proximal Intracranial Artery Stenosis or Occlusion: CT Diagnosis, MRI Findings, and Emergency Stroke Prevention Guide
Introduction A 76-year-old woman experiences repeated brief episodes of weakness and speech difficulty. Symptoms disappear within minutes. Family members assume stress or fatigue. Yet brain imaging reveals a dangerous reality: recurrent transient ischemic attacks (TIA) caused by proximal intracranial artery stenosis or occlusion . This condition is one of the most underestimated neurological emergencies in modern medicine. TIAs are often called “mini-strokes,” but recurrent attacks may signal an unstable cerebral circulation and a high short-term risk of disabling ischemic stroke . For clinicians, patients, and radiology readers alike, rapid medical imaging , especially CT scan diagnosis , MRI, vascular imaging, and expert radiology interpretation , can be life-saving. This comprehensive guide explains the pathophysiology, epidemiology, imaging findings, differential diagnosis, treatment pathways, and prognosis of recurrent TIA due to proximal intracranial artery disease....
