Atretic meningocele is a rare subtype of encefalocele. It represents a small, skin-covered, sub scalp lesion that contains meanings, neural and glial rests.

Encephalocele in general is a very rare congenital malformation of the central nervous system. It is the result of failure of the surface ectoderm to separate from the neuroectoderm. This leads to a bony defect which allows herniation of the meanings or brain tissue and spinal fluids.

Atretic meningocele is usually located in the midline of the parietal or occipital region.

In this paper we will try to deal with the etiopathogenesis, frequency, associated anomalies and with imaging findings.

In 1964, McLaurin reported seven children with a diagnosis of parietal meningocele, among a series of 13 children with parietal cephaloceles. Since that time, a number of investigators had reported small, skin-covered midline sub scalp masses or cysts variably described as atretic cephaloceles, atypical meningoceles, rudimentary meningoceles, meningeal heterotopias, or meningocele manque. These rare lesions generally occur within a few centimeters of the lambda, which in adults is the occipital rounded angle that corresponds to the point of meeting of the sagittal suture with the lamboide suture (Figure 1). In fetal life it corresponds to the posterior fontanel. These lesions contain meninges and neural rests, with approximately half of the reported cases are parietal in location.
