Cerebral angiitis or central side effects after lumbar myelography (with intracerebral vascular spasm)

: This is a case report of severe neurological complications following lumbar radiculography with the non-ionic x-ray contrast agent Iopamidol. The complication, which consisted of serious mnestic disturbances and various neurological deficits including hemiparesis, was due to intracerebral vascular spasms, demonstrated by cerebral angiography, and TCD followed by multiple cerebral infarctions, demonstrated by MRI. A possible causal relationship between the cerebral vascular spasm and intrathecal administration of Iopamidol is discussed.
