Contrast medium-induced seizures and prolonged motor weakness after cerebral angiography: case report.
BACKGROUND
Neurological complications of cerebral angiography are usually embolic events resulting in stroke or seizure of vascular origin. Contrast media rarely induce neurological complications.


METHODS
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.


CONCLUSIONS
Although rare, we should take into consideration that contrast media may induce neurological complications after cerebral angiography.
