Dermoid cyst with cerebellar meningoencephalocele at different locations accompanied by posterior fossa abnormalities: case report

Abstract

Dermoid cysts in the head and neck region may be accompanied by posterior fossa abnormalities.

Nasofrontal encephalocele in a child, associated with a nasal dermal sinus in his mother: familial cranial malformations. Illustrative case

“…Dermal sinuses can be found at any part of the neuraxis, though rarely in the nasal area, and can result from an imperfect separation of the ectoderm and neuroectoderm during the 3rd to 5th weeks of gestational age. 4 The association of a dermoid cyst and an encephalocele in a patient has been reported by Tokmak et al 5 They described a 15-year-old girl with a painful mass at the base of her mouth in the upper neck, which was found to be a dermoid cyst. Craniocervical MRI for more investigation of that lesion confirmed an occipital bony defect with a cerebellar encephalomeningocele.…”

“…Craniocervical MRI for more investigation of that lesion confirmed an occipital bony defect with a cerebellar encephalomeningocele. 5 The occurrence of a dermal sinus with another congenital abnormality, including a dermal sinus, myelomeningocele, and meningocele in two persons of a family, has been reported before. 4 Ansari et al reported a 2-year-old boy with a complicated occipital dermal sinus and intracranial dermoid tumor and abscess.…”

“…Moreover, an abnormal karyotype like trisomy 18 and 13 has been associated with some kinds of NTDs and iniencephaly. 2 , 3 , 5 , 7 , 9 …”
