Background:
Balamuthia mandrillaris is a recently recognized cause of a rare, devastating infection, granulomatous amoebic encephalitis (GAE). Presenting symptoms of GAE are nonspecific and can last for months before becoming clinically significant. Once the infection involves the central nervous system, death often results within days to weeks. A high degree of clinical suspicion is needed to correctly diagnose this infection because definitive diagnostic tests are presently limited, and even then there are only sparse data concerning effective treatment. The importance of early diagnosis is emphasized because delay likely contributes to the extremely high mortality with this infection.
Methods:
This study presents a previously healthy, immunocompetent 2-year-old female patient who succumbed to GAE secondary to B. mandrillaris, with the intention of raising awareness of this devastating infection.
Results:
Balamuthia amoebic encephalitis is a devastating form of amoebic encephalitis that is increasingly reported in the literature.
Conclusions:
GAE should be considered for a patient with atypical encephalitis and single or multiple lesions with surrounding edema evident on neurodiagnostic imaging.
Insights
Granulomatous amoebic encephalitis (GAE), caused by Balamuthia mandrillaris, is a rare but deadly infection. Early diagnosis and treatment are critical for improving patient outcomes in this devastating neurological disease.
Area of Science:
- Neurology
- Infectious Diseases
- Parasitology
Background:
- Balamuthia mandrillaris is a cause of granulomatous amoebic encephalitis (GAE), a rare and severe infection.
- GAE symptoms are nonspecific and can progress rapidly once the central nervous system is involved.
- Early diagnosis is crucial due to limited effective treatments and high mortality.
Observation:
- A previously healthy, immunocompetent 2-year-old female patient developed GAE secondary to B. mandrillaris.
- The patient ultimately succumbed to the infection, highlighting its devastating nature.
Findings:
- Balamuthia amoebic encephalitis is an increasingly reported condition in medical literature.
- Neuroimaging may reveal single or multiple brain lesions with surrounding edema.
Implications:
- GAE should be considered in patients presenting with atypical encephalitis.
- Increased awareness and diagnostic vigilance are necessary for prompt GAE identification and management.
