Summary
Neuroschistosomiasis is a rare complication of schistosomiasis, often presenting as an intracerebral mass. Early diagnosis and treatment with praziquantel can lead to full recovery.
Area of Science:
- Neurology
- Infectious Diseases
- Parasitology
Background:
- Schistosomiasis is a parasitic disease endemic in tropical regions.
- Neurological complications are rare, with intracerebral mass lesions being particularly uncommon.
- Timely diagnosis is crucial for effective management and patient outcomes.
Observation:
- A 26-year-old male immigrant from Brazil presented with headaches and visual disturbances.
- Magnetic resonance imaging revealed an enhancing lesion in the right occipital lobe, suggestive of a mass.
- Stereotactic brain biopsy confirmed intraparenchymal granulomas with Schistosoma masoni eggs.
Findings:
- The patient was diagnosed with neuroschistosomiasis presenting as an intracerebral mass.
- Treatment with praziquantel and steroids led to complete symptom resolution.
- Follow-up imaging showed normalization of brain structures.
Implications:
- Neuroschistosomiasis should be considered in the differential diagnosis of intracerebral mass lesions, especially in endemic populations.
- This case highlights the importance of considering parasitic infections in neurological presentations.
- Prompt treatment can prevent severe neurological sequelae and ensure favorable prognosis.
