Introduction:
Intramedullary spinal cord abscesses (ISCA) are rare and caused by central nervous system infections. Although polymicrobial infections are rarely seen in ISCAs, isolation of the causative pathogen is important for treatment. Here, we describe a very rare case of ISCA resulting from a mixed Streptococcus and Actinomyces infection.
Case Presentation:
An 82-year-old man presented with acute posterior cervical pain and progressive quadriplegia. Radiological investigations revealed a mass lesion showing marginal enhancement at the level of the C3-4 vertebrae. Microsurgical drainage was performed, and Streptococcus and Actinomyces were identified as causative agents. Subsequent antibiotic treatment was noted to be beneficial to the patient.
Discussion:
This case suggests that mixed infection can develop into ISCA depending on the causative agents such as Actinomyces. Prompt pathogen-directed antibacterial therapy is required for ISCA treatment.
Insights
This case highlights a rare mixed Streptococcus and Actinomyces infection causing an intramedullary spinal cord abscess (ISCA). Prompt, targeted antibiotic therapy is crucial for treating this serious central nervous system infection.
Area of Science:
- Neurology
- Infectious Diseases
- Microbiology
Background:
- Intramedullary spinal cord abscesses (ISCAs) are uncommon but serious central nervous system infections.
- Polymicrobial infections are rare in ISCAs, making pathogen identification critical for effective treatment.
- This report details an exceptionally rare ISCA caused by a mixed Streptococcus and Actinomyces infection.
Approach:
- A case study of an 82-year-old male presenting with cervical pain and quadriplegia.
- Radiological imaging identified a C3-4 level mass with marginal enhancement.
- Surgical drainage and subsequent antibiotic therapy were employed.
Key Points:
- Identification of both Streptococcus and Actinomyces as causative agents in the ISCA.
- Successful treatment outcome following targeted antibiotic administration.
- Demonstrates the potential for mixed infections to cause ISCA.
Conclusions:
- Mixed infections, including Actinomyces, can lead to the development of ISCA.
- Effective ISCA management necessitates prompt identification and pathogen-directed antibacterial therapy.
