We conclude that to plan the safest possible repair, preoperative evaluation of intrasphenoidal
meningoencephalocele by MRI is essential to confirming the extension of the lesion and any associated abnormalities.
Trans-sphenoidal
meningoencephaloceles are usually congenital anomalies, although cranial trauma as a cause has been reported.
In this article, we report an unusual case of a temporal lobe
meningoencephalocele in a cranial bone (rather than a paranasal sinus) that appeared as a lytic lesion of the pterygoid process.
Possible malignancies include craniopharyngioma, meningioma, chordoma, glioma,
meningoencephalocele, nasopharyngeal tumor, sphenoid sinus tumor, internal carotid artery aneurysm, sphenoid osteoma, cholesteatoma, and fibrous dysplasia.
Many pathological masses in the nose may look like antrochoanal polyp, for example dermoid cysts,
meningoencephaloceles, teratomae or sphenochoanal polyps [8].
Retinoid embryopathy ranges from craniofacial dysmorphias appendagial abnormalities to
meningoencephaloceles.
Benign processes include nasal polyps, mucoceles,
meningoencephaloceles, chrondromas, osteomas, ossifying fibromas, and cementomas.
Some patients had multiple defects in the tegmen and dura, and some can have
meningoencephaloceles, can be seen behind the tympanic membrane.
The differential diagnosis of nasopharyngeal cysts includes adenoid hypertrophy, branchial cleft cysts, meningoceles,
meningoencephaloceles, antrochoanal polyps, sphenochoanal polyps, and malignant tumors.
