Abstract:
A 64-year-old woman who presented with acute meningoencephalitis was reported. Cerebrospinal fluid (CSF) revealed polymorphonuclear pleocytosis with gram-positive cocci. Blood and CSF grew microaerophilic streptococcus. The patient was treated with intravenous penicillin G and chloramphenicol for 2 weeks and recovered without sequela. There was no evidence of any focus of infection prone to the development of this infection.
Insights
A rare case of acute meningoencephalitis caused by microaerophilic streptococcus in an adult woman was successfully treated. Prompt antibiotic therapy with penicillin G and chloramphenicol led to a full recovery without lasting effects.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Acute meningoencephalitis is a severe neurological condition requiring prompt diagnosis and treatment.
- Microaerophilic streptococcus is an uncommon pathogen, particularly in adult neurological infections.
Observation:
- A 64-year-old woman presented with acute meningoencephalitis.
- Cerebrospinal fluid analysis showed polymorphonuclear pleocytosis and gram-positive cocci.
- Blood and cerebrospinal fluid cultures identified microaerophilic streptococcus.
Findings:
- The patient received intravenous penicillin G and chloramphenicol for two weeks.
- Complete recovery was achieved without any sequelae.
- No identifiable source for the infection was found.
Implications:
- This case highlights the importance of considering and identifying microaerophilic streptococcus in cases of meningoencephalitis.
- Effective treatment strategies involve timely administration of appropriate antibiotics.
- Further research may elucidate the pathogenesis of such infections in the absence of a clear focus.
