Atretic Meningocele: Etiopathogenesis, Frequency, Anomaly Associations and Imaging Findings

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.
