Introduction:
Infections of the central nervous system by free-living amoeba are a rare phenomenon around the world. They present as a necrotising haemorrhagic acute meningoencephalitis, with a fatality rate close to 100% or as granulomatous amoebic encephalitis with a chronic progression.
Case Report:
We describe a fatal case of primary amoebic meningoencephalitis produced by Naegleria fowleri in an 8-year-old child, with a history of immersion in a freshwater reservoir 52 hours before death.
Conclusion:
Laboratory studies carried out before death did not enable a diagnosis to be reached while the patient was alive. Diagnosis was made in the course of the post-mortem examination, where the presence of amoeba trophozoites was identified.
Insights
Primary amoebic meningoencephalitis caused by Naegleria fowleri is a rare and fatal infection. Diagnosis was only confirmed post-mortem, highlighting challenges in early detection of this severe CNS amoebic infection.
Area of Science:
- Neurology
- Infectious Diseases
- Parasitology
Background:
- Free-living amoeba infections of the central nervous system (CNS) are globally rare.
- These infections manifest as acute necrotizing hemorrhagic meningoencephalitis (nearly 100% fatality) or chronic granulomatous amoebic encephalitis.
Observation:
- A case of fatal primary amoebic meningoencephalitis (PAM) caused by Naegleria fowleri in an 8-year-old child is presented.
- The child had a history of freshwater reservoir immersion 52 hours prior to death.
Findings:
- Pre-mortem laboratory studies failed to establish a diagnosis.
- Amoeba trophozoites were identified during the post-mortem examination, confirming the diagnosis.
Implications:
- This case underscores the diagnostic challenges associated with Naegleria fowleri infections.
- Early and accurate diagnosis is critical for potential therapeutic interventions in CNS amoebic infections.
