A Heidenhain variant of Creutzfeldt–Jakob disease: forensic implication

To investigate whether typical clinical, diagnostic and neuropathological findings can be identified in a patient with a postmortem diagnosis of a Heidenhain variant of Creutzfeldt–Jakob disease (CJD). We report a new case of CJD in a rare variant. A man admitted to hospital with cefalea and vision disorder. Clinical and neurological examination showed headache, vision reduction, psychomotor anxiety and progressive torpor. The patient died 4 h after admission to hospital. The autopsy findings included marked encephalic vascular congestion. Hystoneurology examination showed no macroscopic anomaly. Microscopy findings included neuronal loss, gliosis in striate area with arachnoid cells and cerebellum microspongiosis. Creutzfeldt–Jakob disease is a rare neurodegenerative human disorder. The prion hypothesis as an explanatory model is currently favoured by majority of researchers. A disease course described by Heidenhain including the leading symptoms of a visual disorder and rapid progression. This report emphasize the multidisciplinary role (forensic, neurogenetic and neurohistologic) for diagnosis and to standardize a protocol to investigate.
