Central nervous system (CNS) infection by Trypanosoma cruzi (T. cruzi) is rare but serious in immunocompromised individuals. Early diagnosis and treatment are critical for managing this opportunistic infection.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Central nervous system (CNS) involvement in Trypanosoma cruzi infection is uncommon, particularly in non-endemic regions.
  • HIV-compromised individuals are at increased risk for opportunistic CNS infections.

Observation:

  • A 36-year-old female presented with neurological symptoms including headache, nausea, vomiting, somnolence, memory deficits, and hemiparesis.
  • Brain CT revealed a lesion in the corpus callosum, and lumbar puncture showed elevated pressure, lymphocytic pleocytosis, low glucose, high protein, and the presence of Trypanosoma parasites.
  • The patient was diagnosed with HIV and cerebral trypanosomiasis.

Findings:

  • Direct observation of Trypanosoma parasites in cerebrospinal fluid (CSF) is a rare diagnostic method for CNS infection.

  • Benznidazole treatment led to clinical and radiographic improvement, but the patient ultimately succumbed to respiratory failure.

    • Implications:

    • Cerebral trypanosomiasis should be considered in the differential diagnosis of intracranial space-occupying lesions, especially in immunocompromised patients from endemic areas.
    • Despite treatment, T. cruzi CNS infection carries a high mortality rate, underscoring the need for prompt diagnosis and management.
