RESUMEN

Encephalocele is a congenital malformation caused by a neural tube defect during embryonic development. We report a case of posterior encephalocele in a 7-month-old infant with a painful occipital mass known since birth. Pathological examination of the mass showed different mature tissues derived from the brain and its coverings (e.g., neuroglia, ependymal canals and clusters of meningothelial cells). A diagnosis of encephalocele was made. The different forms of neural tube defect will be briefly discussed, especially the "aborted" forms (e.g., non-specific midline mass lesion or angioma) that the pathologist may encounter in his/her daily practice.
