Spontaneous intracerebral hemorrhage (ICH) is frequently associated with intraventricular hemorrhage (IVH), which is an independent predictor of poor outcome. The purpose of this study was to examine the relationship between ICH volume and anatomic location to IVH, and to determine if ICH decompression into the ventricle is truly beneficial. ⋯ Intraventricular hemorrhage (IVH) occurs in nearly half of patients with spontaneous intracerebral hemorrhage (ICH) and is related to ICH volume and location. IVH is likely to occur within the "decompression ranges" that take into account both ICH location and volume. Further, spontaneous ventricular decompression does not translate to better clinical outcome. This information may prove useful for future ICH trials, and to the clinician communicating with patients and families.

To assess the relationship between regional brain volume changes and traumatic brain injury (TBI) severity in patients with and without focal lesions. ⋯ Patterns of parenchymal volumetric changes can differentiate among levels of traumatic brain injury (TBI) severity, even in mild TBI. TBI causes a spatially extensive pattern of volume loss that reflects independent but overlapping contributions of focal and diffuse injury.
