Intracerebral hemorrhage after lumbar myelography with iohexol: report of a case and review of the literature.

Intracranial hemorrhage is an uncommon complication of dural puncture. In most instances, hematomas are subdural; they may be unilateral or bilateral. Rarely are intraparenchymal cerebral hemorrhages related to dural puncture. This report describes a delayed occurrence of bilateral intraparenchymal hemorrhages in a 38-year-old woman 7 days after lumbar myelography with iohexol. A review of the literature is presented.
