Abstract: | Brain-stem death is a state in which brain-stem functions have been ceased whereas the hemispheres still have electrical activity. We report a patient with a haematoma over the cerebellum and the pons who showed a preserved electroencephalogram and VEPs whereas all clinical signs of cerebral death were present. Normal VEPs in isolated brain-stem death have been not yet been reported. We conclude that in any case of infratentorial lesion, an electroencephalogram should be recorded for the diagnosis of brain death. |
