Abstract:
Anthrax is primarily a disease of herbivores, but it also causes cutaneous, respiratory and gastrointestinal infections in humans. Bacillus anthracis is an uncommon cause of meningitis and generally produces a haemorrhagic meningoencephalitis. We present the CT and MR findings of anthrax meningoencephalitis due to the cutaneous form of anthrax in a 12-year-old boy. They showed focal intracerebral haemorrhage with leptomeningeal enhancement.
Insights
Anthrax meningitis is rare but serious. This case highlights CT and MR imaging findings of focal intracerebral hemorrhage and leptomeningeal enhancement in a child with cutaneous anthrax.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- Anthrax, caused by Bacillus anthracis, primarily affects herbivores but can infect humans through cutaneous, respiratory, or gastrointestinal routes.
- Anthrax meningitis is an uncommon but severe complication, typically presenting as hemorrhagic meningoencephalitis.
Observation:
- A 12-year-old boy presented with symptoms suggestive of central nervous system involvement following cutaneous anthrax.
- Diagnostic imaging, including CT and MRI, was performed to evaluate the neurological complications.
Findings:
- Imaging revealed focal intracerebral hemorrhage, a significant finding in the context of anthrax infection.
- Leptomeningeal enhancement was observed, indicating inflammation of the membranes surrounding the brain and spinal cord.
Implications:
- This case underscores the importance of considering anthrax meningoencephalitis in patients with neurological symptoms and a history of cutaneous anthrax.
- Radiological findings of intracerebral hemorrhage and leptomeningeal enhancement are crucial for diagnosing this rare but life-threatening condition.
- Early recognition and appropriate management are vital for improving outcomes in anthrax meningoencephalitis.
