Background And Importance:
Neurological complications of cerebral angiography are usually embolic events resulting in stroke or seizure of vascular origin. Contrast media rarely induce neurological complications.
Clinical Presentation:
Repeated seizures and prolonged motor weakness developed in a 26-year-old woman after cerebral angiography. Neurological deficits remained the next day with slow recovery. Repeat magnetic resonance imaging did not demonstrate any cerebral ischemia even on diffusion-weighted images. The contrast medium was the most likely cause of the neurological deficits. She recovered completely after infusion of the osmotic diuretic.
Conclusion:
Although rare, we should take into consideration that contrast media may induce neurological complications after cerebral angiography.
