Abstract:
Propionibacteriumacnes is a Gram-positive bacillus that can be part of the human skin flora. This bacterium infecting the subdural space postoperatively is quite a rare entity. When present, it likely reflects a true infection rather than contamination requiring urgent intervention. We are reporting a rare case of craniotomy for subdural hematoma evacuation complicated by subdural Propionibacterium acnes infection. The infection was successfully treated with surgical debridement and antibiotics.
Insights
Propionibacterium acnes, a skin bacterium, rarely infects the subdural space after surgery. This case highlights a successful treatment of subdural P. acnes infection with debridement and antibiotics.
Area of Science:
- Neuroscience
- Infectious Diseases
- Microbiology
Background:
- Propionibacterium acnes is a common Gram-positive bacterium found on human skin.
- Subdural space infections are uncommon, especially those caused by P. acnes.
Observation:
- A rare case of subdural P. acnes infection following craniotomy for subdural hematoma evacuation is presented.
- The presence of P. acnes in the subdural space postoperatively indicated a true infection, not contamination.
Findings:
- The subdural infection was successfully treated using surgical debridement.
- Antibiotic therapy was administered concurrently with surgical intervention.
Implications:
- This case underscores the importance of recognizing P. acnes as a potential pathogen in postoperative subdural infections.
- Prompt surgical and antibiotic intervention is crucial for managing such rare infections.
