  • Abstract
  • Look Inside

A 75-year-old woman with hypertension suddenly developed ptosis in the left eyelid. Neurological exami-nation revealed left oculomotor nerve palsy. Brain T 2-weighted imaging showed abnormal flow void sign in the proximal portion of left middle cerebral ar-tery. Other MRIs, including gadolinium enhancement, were normal. However, brain 3 D-MRA, using time-of-flight sequence, did not disclose any intracranial aneurysms. 3 D-CT angiography revealed left internal carotid-posterior communicating artery (IC-PC) aneu-rysm.
