Intraventricular hemorrhage classification
Primary intraventricular hemorrhage (IVH) or IVH secondary to intracerebral hemorrhage (ICH) and subarachnoid hemorrhage (SAH) with extension to the ventricles.
Primary Intraventricular hemorrhage
Some of the more common causes of primary intraventricular hemorrhage in adults include
aneurysm (e.g. PICA aneurysms have a tendency to fill the 4th ventricle, with little basal cistern blood)
Intraventricular arteriovenous malformations (AVM)
subependymal cavernous malformations
anticoagulation therapy/coagulopathy
ependymoma
choroid plexus / intraventricular metastases
adjacent parenchymal tumors (e.g. glioblastoma)
