[Otogenic meningitis after skull fracture in a child (histopathologic contribution)]

Area of Science:

• Otolaryngology
• Neurology
• Pathology

Background:

• Otogenic meningitis is a severe complication of middle ear infections.
• Skull base fractures can create abnormal connections between the middle ear and intracranial space.
• Long-term sequelae of pediatric skull base trauma are not well-documented.

Observation:

• Histological examination of the temporal bone from a patient who died of meningitis revealed an unhealed transverse fracture.
• This fracture extended through the endochondral layer of the bony labyrinth.
• A persistent communication pathway existed between the middle ear and the intracranial cavity throughout the patient's life.

Findings:

• The unhealed fracture served as a direct route for infection from the middle ear to the brain.
• Despite treatment with high-dose antibiotics, the patient succumbed to fulminant otogenic meningitis.
• The findings highlight the critical importance of the bony labyrinth's integrity in preventing intracranial infections.

Implications:

• This case underscores the potential for delayed, life-threatening complications from seemingly resolved childhood skull base injuries.
• It emphasizes the limitations of antibiotic therapy in cases with persistent anatomical predisposing factors for meningitis.
• Further research into the long-term management and surveillance of individuals with skull base defects is warranted.
