title: [Intraventricular extravasation of contrast media through primary intraventricular hemorrhage (author's transl)].
abstract: A 22-year-old woman was admitted following the sudden onset of severe headache and loss of consciousness. On admission, she was delirious with nuchal rigidity. A lumbar puncture showed bloody spinal fluid. Laboratory studies revealed no abnormalities. Her consciousness state became clear 2 days after the attack. Computerized tomography taken 7 days after the attack revealed intraventricular hemorrhage in the right trigonum. Emergent right carotid angiography was performed. The intraventricular extravasation of contrast media was shown in the region of the right trigonum. One hour after the angiography, she was semicomatose with left flaccid hemiplegia. Reexamination of computerized tomography revealed diffuse intraventricular hemorrhage and periventricular intracerebral hematoma in the right parieto-temporal lobe. Emergent operation was performed and intracerebral hematoma was extirpated. Good postoperative results were obtained after ventriculoperitoneal shunting 46 days after removal of the hematoma. In our review of the literature, intraventricular extravasation of contrast media through primary intraventricular hemorrhage has not been reported.U
