[Differential diagnosis of status epilepticus in intensive care: about one case of sporadic Creutzfeldt-Jakob].

A 78-year-old man was admitted in the intensive care unit for epilepsy seizure (tonic-clonic seizure). Since three months, his wife reports motor dysfunction (weakness) and since two weeks, rapidly progressive changes in cognition (apraxia, akinetic mutism). The diagnosis of probable sporadic Creutzfeldt-Jakob on the basis of clinical, EEG and MRI lesions was made. Refining diagnostic criteria is probably needed, including the usefulness of repeated MRI with FLAIR and diffusion-weighted imaging.
