Rudimentary meningocele presenting with a scalp hair tuft. Report of two cases

Congenital Stigmatıc Alopecıas Associated with Occult Spinal Dysraphısm

“…According to our literature research, only two types of hair abnormalities of the scalp which are associated with underlying cranial neural tube defect or neurological sequele had been reported [19][20][21][22][23]. One of them is "scalp hair tuft" and only a few cases have been reported up to now [19,24]. The lesion is described as a midline hair tuft over underlying rudimentary meningocele, and usually found on the occiput [19].…”

“…One of them is "scalp hair tuft" and only a few cases have been reported up to now [19,24]. The lesion is described as a midline hair tuft over underlying rudimentary meningocele, and usually found on the occiput [19]. The other is "hair collar sign" that is collarette of dark, coarse hair around an circumscribed area of alopecia such as aplasia cutis congenita [22,25].…”

A Case of Rudimentary Lateral Parietal Cephalocele: Extracranial Meningothelial and Glial Tissue without Intracranial Communication or Bony Defect

“…Some authors suggest that rudimentary cephaloceles exist on a continuum with classic cephaloceles, representing an abortive form of cephalocele that spontaneously arrests in the development of the malformation [2, 10]. Another explanation contends that meningoceles with herniated meninges protrudes through a small cranial defect that subsequently involutes in utero, leaving behind remnants of heterotopic glial rests [7, 8].…”

“…Proper preoperative evaluation should include imaging studies to identify a bony defect, intracranial extension of the lesion, or possible attachment to intracranial vascular structures [10]. Surgical intervention is recommended for cosmesis, preventing future rupture or ulceration of the lesion, decreasing pain at the site, and to obtain histological diagnosis [2].…”

A case of occipital rudimentary cephalocoele

“…[ 1 2 3 ] Various authors have reported small, skin-covered midline sub-scalp masses or cysts described as atretic cephalocoeles, atypical meningoceles, rudimentary meningoceles, and meningeal heterotopias. [ 1 2 3 4 5 6 7 ] Atretic cephalocoeles are different from common meningocele, in that they lack an intracranial communication.…”
