Abstract

Transient cortical blindness (TCB) is a rare but well-known complication of cerebral angiography. Its pathophysiology remains uncertain. We would like to report a case of TCB in a patient during a follow up vertebral angiogram for post-coil embolization of left posterior inferior cerebellar artery aneurysm. Patient's vision was resumed spontaneously within 24 hours after angiography, with no residual neurological deficit in subsequent clinical follow up. Multi-modality imaging evaluation including vertebral angiography, brain CT and MRI performed on same day are presented.

Figure

• 

  Fig. 1 Anteroposterior (A) and lateral (B) vertebral angiograms show no sign of vascular occlusion or spasm in the vertebrobasilar territory. Note the coiled aneurysm in the origin site of left posteroinferior cerebellar artery.

• 

  Fig. 2 Brain CT obtained 2 hours after angiography shows no evidence of acute infarction or intracranial hemorrhage.

• 

  Fig. 3 Post-contrast FLAIR images (A, B) obtained 3 hours after angiography show high signal intensity lesions in the sulcal spaces of bilateral parieto-occipital lobes.

• 

  Fig. 4 Diffusion image obtained 3 hours after angiography shows no diffusion restricted lesions.
