Background:
Nosocomial infections caused by Serratia marcescens mostly occurred in pediatrics and it was very rarely reported after adult surgery. Here, an intracranial abscess caused by Serratia marcescens was reported. We report a rare case of a postoperative intracranial abscess caused by Serratia marcescens in a 63-year-old male patient with a left parietal mass. The patient underwent resection of the mass on June 1, 2022, and the postoperative pathology revealed an angiomatous meningioma, WHO I. He then experienced recurrent worsening of right limb movements, and repeated cranial CT scans showed oozing blood and obvious low-density shadows around the operation area. Delayed wound healing was considered. Subsequently, a large amount of pus was extracted from the wound. The etiological test showed that Serratia marcescens infection occurred before the removal of the artificial titanium mesh. Antibiotics were initiated based on the results of drug susceptibility tests. At present, the patient is recovering well and is still closely monitored during follow-up.
Conclusion:
It is rare for Serratia marcescens to cause brain abscesses without any obvious signs of infection. This report provided in detail our experience of a warning postoperative asymptomatic brain abscess caused by an uncommon pathogen.
Insights
A rare case of Serratia marcescens causing a postoperative brain abscess in an adult male is detailed. This report highlights an uncommon pathogen leading to a brain abscess without typical infection signs.
Area of Science:
- Neuroscience
- Infectious Diseases
- Neurosurgery
Background:
- Nosocomial infections are typically seen in pediatric patients.
- Serratia marcescens is an uncommon cause of infection in adult surgical patients.
- Intracranial abscesses are rare complications of neurosurgery.
Observation:
- A 63-year-old male developed a postoperative intracranial abscess.
- The patient had a left parietal mass (angiomatous meningioma, WHO I) resected.
- Symptoms included worsening limb movements and CT findings of fluid collection and low-density areas.
Findings:
- A large amount of pus was extracted from the surgical site.
- Etiological tests identified Serratia marcescens infection.
- The infection was linked to the presence of an artificial titanium mesh.
- Antibiotic treatment was guided by drug susceptibility testing.
Implications:
- This case underscores the potential for Serratia marcescens to cause asymptomatic brain abscesses post-surgery.
- It highlights the importance of considering uncommon pathogens in postoperative infections.
- Early identification and targeted antibiotic therapy are crucial for favorable outcomes.
