Anomalies that need to be excluded in these cases include head and neck masses causing compression, Arnold Chiari malformation, meningoencephalocele
, and hydrocephalus.
18%) which occupied second position was used in Nasopharyngeal Angiofibroma 7, Inverted Papilloma 6, rhinosporidiosis 4, bleeding polyposis 3, granuloma pyogenicum 1, angiomyxomatous polyp 1, pleomorphic adenoma 1 and meningoencephalocele
Environmental factors along with congenital factors are considered to be critical in etiology and development of meningocele and meningoencephalocele
Aslanbey et al.
The protrusion is termed a meningocele if it contains meninges and cerebrospinal fluid (CSF) and a meningoencephalocele
or encephalocele when it also contains brain tissue.
, encephalocele, dermoid cyst, glioma, hemangioma and rhabdomyosarcoma are included in the differential diagnosis (1).
Encephaloceles are anomalous herniations of the meninges, or brainmatter and meninges, beyond the boundaries of the cranium; referred to as meningocele and meningoencephalocele
(TEME) is a very rarely encountered congenital malformation characterized by a protrusion of cerebral tissue and meninges through a congenital defect in the cranial bones.
This is suggestive of naso-ethmoidal meningoencephalocele
Abnormal development of mouse embryos has been observed in vitro (Chan and Ng 1995) and there is at least one report of human occipital meningoencephalocele
associated with use of the extract by the mother (Takei et al.
Its differential diagnosis include nasal polyp, antrochoanal polyp, angiofibroma when patient is adolescent, meningocele, meningoencephalocele
, papilloma, hemangiosarcoma, squamous cell carcinoma.
