The Utility of Magnetic Resonance Imaging in the Diagnosis of Intranasal Meningoencephaloceles

Surgery of Anterior Skull Base Lesions in Children

“…Imaging by CT reliably determines the bone defect of the skull base, 16 whereas MRI gives information on associated brain abnormalities. 17 In children, the use of CT should be restricted, and generally, an MRI is sufficient, even in skull base pathologies. A biopsy of the suspected meningo(encephalo)cele is contraindicated.…”

Surgical Treatment of a Canine Intranasal Meningoencephalocele

“…MRI is also useful to detect other intracranial anomalies 5,8,20 . In some people, CT scan has failed to distinguish between chronic nasal inflammation and an intranasal meningoencephalocele 24 . Seemingly, both imaging modalities should be used before surgical planning 22 …”

Adult intranasal meningoencephalocele presenting as a nasal polyp

“…3D CT is particularly useful in planning operative strategy. Zinreich et al 21 reported three patients where the diagnosis of intranasal meningoencephalocele was made by MRI. In these cases, initial clinical evaluation and CT failed to distinguish between chronic inflammation and intranasal meningoencephalocele.…”
