Neuroradiological, neurophysiological and anatomopathological study of a case of locked-in syndrome.

We report an anatomoclinical case of locked-in syndrome together with the neuroradiological and neurophysiological findings. MRI confirmed its value in the diagnosis of posterior cranial fossa pathology while the neurophysiological work-up (BAEPs, SEPs, MAPs and TEPs) revealed that the lesion may have broader functional implications than may be gauged from the neuroradiological and pathological evidence. Evoked potentials may therefore be of considerable importance in pinpointing brainstem lesions.
