Abstract:
We report a case of a 30-year-old man who presented with altered mental status, fever, headache and vomiting for 3 days. An initial CT scan of the brain revealed the presence of pneumocephalus with a bony defect in the anterior cranial fossa. The pneumocephalus was not explained initially and the patient was re-examined for any signs of trauma to the face, and a review of the history revealed a series of three traumatic events months prior to this illness. Further laboratory studies revealed Streptococcus pneumoniae in the blood and bacterial meningitis. He was treated with antibiotics and was later taken up for endoscopic repair of the skull base defect. This case highlights the importance of recognising post-traumatic pneumocephalus with superimposed meningitis and sepsis months after a traumatic event to the skull base.
Insights
A traumatic brain injury led to delayed pneumocephalus and meningitis in a 30-year-old man. Prompt antibiotic treatment and surgical repair were crucial for recovery, emphasizing the need to consider delayed complications after skull base trauma.
Area of Science:
- Neurology
- Infectious Diseases
- Neurosurgery
Background:
- Skull base defects can lead to delayed intracranial complications.
- Traumatic events may predispose individuals to conditions like pneumocephalus.
- Recognizing subtle or delayed presentations of post-traumatic complications is clinically significant.
Observation:
- A 30-year-old male presented with altered mental status, fever, headache, and vomiting.
- Brain CT revealed pneumocephalus and an anterior cranial fossa bony defect.
- History revealed prior traumatic events, suggesting a link to the current condition.
Findings:
- Laboratory studies confirmed Streptococcus pneumoniae in the blood, indicating bacterial meningitis and sepsis.
- The pneumocephalus was attributed to a post-traumatic skull base defect.
- The patient received antibiotic treatment and underwent endoscopic repair of the defect.
Implications:
- This case underscores the importance of considering delayed post-traumatic pneumocephalus, meningitis, and sepsis.
- Early recognition and management of such conditions are vital for patient outcomes.
- Endoscopic skull base repair offers a viable treatment option for complex defects.
