Insights
This study details a rare Heidenhain variant of Creutzfeldt-Jakob disease (CJD), highlighting its rapid progression and visual symptoms. Neuropathological findings confirmed the diagnosis, emphasizing the need for multidisciplinary investigation.
Area of Science:
- Neurology
- Pathology
Background:
- Creutzfeldt-Jakob disease (CJD) is a rare, fatal neurodegenerative disorder.
- The Heidenhain variant is characterized by prominent early visual disturbances and rapid progression.
Observation:
- A case report of a male patient presenting with headache and vision disorder, rapidly progressing to death within 4 hours of hospital admission.
- Clinical examination revealed headache, reduced vision, psychomotor agitation, and progressive stupor.
- Autopsy showed significant cerebral vascular congestion, with microscopic findings of neuronal loss, gliosis, and microspongiosis in the striate cortex and cerebellum.
Findings:
- Microscopic examination confirmed neuronal loss, gliosis, and microspongiosis, consistent with CJD.
- No macroscopic anomalies were observed during the hystoneurology examination.
- The findings align with the neuropathological characteristics of the Heidenhain variant of CJD.
Implications:
- This case underscores the importance of recognizing the Heidenhain variant of CJD based on clinical and neuropathological data.
- Highlights the necessity of a multidisciplinary approach involving forensic, neurogenetic, and neurohistologic expertise for accurate diagnosis.
- Suggests the need for standardized protocols to investigate CJD cases, particularly rare variants.
Abstract:
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.
