  • Title: Contrast medium-induced seizures and prolonged motor weakness after cerebral angiography: case report.
    Author: Mitsuyama T, Sato S, Ishii A, Kawamata T.
    Journal: Neurosurgery; 2010 Nov; 67(5):E1460-3; discussion E1463. PubMed ID: 20948393.
    Abstract:
    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.
