Intranasal meningoencephalocele with recurrent meningitis
Surgical Neurology
|July 1, 1979
Abstract:
Two patients presented with repeated bouts of meningitis. RISA cisternography established the diagnosis in both cases. An intranasal meningoencephalocele was the cause of these infections. Frontal craniotomy and section of the peduncular connection of the meningoencephalocele and sealing of the bony defect was successfully performed in both cases. Postoperative investigations showed complete cure.
Insights
Recurrent meningitis in two patients was diagnosed using RISA cisternography, revealing an intranasal meningoencephalocele as the cause. Surgical repair successfully cured both cases, demonstrating effective treatment for this rare condition.
Area of Science:
- Neurosurgery
- Neurology
- Radiology
Background:
- Recurrent meningitis poses a diagnostic challenge.
- Intranasal meningoencephaloceles are rare causes of cerebrospinal fluid leaks and meningitis.
- Timely diagnosis is crucial for effective management.
Observation:
- Two patients experienced recurrent meningitis.
- RISA cisternography identified an intranasal meningoencephalocele in both individuals.
- This defect allowed communication between the sinonasal cavity and the cranial vault.
Findings:
- Surgical intervention involved frontal craniotomy.
- The peduncular connection of the meningoencephalocele was severed.
- The bony defect was sealed, successfully addressing the cerebrospinal fluid leak.
Implications:
- Surgical correction of intranasal meningoencephaloceles is an effective treatment for recurrent meningitis.
- RISA cisternography is a valuable diagnostic tool for cerebrospinal fluid leaks.
- Early diagnosis and surgical management can lead to complete cure and prevent further infectious complications.
