Does "black" brain mean doom? Computed tomography in the prediction of outcome in children with severe head injuries: "benign" vs "malignant" brain swelling.
A retrospective review of initial and subsequent CT scans of 179 children who has suffered severe head injury requiring admission to intensive care was performed. The aim was to define the CT appearance which was always associated with a poor outcome. The children whose brain showed poor definition of basal ganglia and grey-white differentiation overall, together with sufficient swelling to obliterate the ambient cistern and third ventricle always died or remained in a vegetative state. Over half of these had reduced brain density, and several had small focal high densities consistent with contusions or petechial haemorrhages. A typical appearance showed homogeneous scans at the levels of the ambient cistern and thalami with no normal internal brain detail. Conversely obliteration of the ambient cistern associated with a large surface collection was compatible with complete recovery if grey-white definition remained normal and treatment was prompt.
