 | | Hemorrhage from a lateral ventricular meningioma does not usually require decompression such as ventricular drainage or shunt emplacement to relieve obstructive hydrocephalus, suggesting that such hemorrhages may be of venous origin, which is insufficient to obstruct CSF flow. | | | Primary gliomas may arise in the ventricles, though have not been associated with hemorrhage, and are more commonly found in the body of the ventricle. | | | Ependymomas are much more common in the ventricular body, are rarely calcified, and have not been associated with hemorrhage. |
