title: Radiological evaluation of cerebral aneurysms in selected clinical presentations.
abstract: OBJECTIVE
  Cerebral aneurysms have different presenting features and, to some extent, a variable clinical course based on the pattern of subarachnoid hemorrhage, the circumstance of their discovery, and the anatomy. Thus, the neuroimaging workup must be tailored accordingly to provide accurate diagnosis and optimal follow-up.
  
  
  METHODS
  The authors suggest neuroradiological evaluation of patients in the emergency room and in cases of perimesencephalic subarachnoid hemorrhage, aneurysmal pattern of subarachnoid hemorrhage with normal angiography, vascular infundibula, unruptured/incidental aneurysms, infectious aneurysms, dissecting aneurysms, dolichoectatic/fusiform aneurysms, intracavernous aneurysms, and traumatic aneurysms.
  
  
  CONCLUSIONS
  Recent neuroimaging advances have contributed to improvement in diagnostic safety and accuracy, allowing a more diligent patient follow-up, improved patient outcome, and enhanced physician perception and clinical judgment.
