Department of Neurology, Seoul National University College of Medicine Department of Neurology, Eulji University School of Medicine* A ruptured arteriovenous malformation (AVM) can induce vasospasm, usually by subarachnoid hemorrhage (SAH). There are several case reports of delayed vasospasm following intraventricular hemorrhage (IVH) from a ruptured AVM without radiologically detectable SAH. We report a case of vasospasm-induced cerebral infarction following primary IVH without any visible SAH in brain CT. In cases of primary IVH, the cerebrospinal fluid may contain blood components and it could be possible for the components to result in vasospasm. Therefore we should be alert to prevent vasospasm not only in SAH but also in primary or secondary IVH even though SAH is not visible in brain image.
