Basal encephalocele associated with morning glory syndrome: case report

ABSTRACT

The basal encephaloceles refer to rare entities and they correspond to herniation of brain tissue through defects of skull along the cribiform plate or the sphenoid bone. A rare morning glory syndrome, with characteristic retinal defect has been reported in association with basal encephaloceles. Hypophysis hormonal deficiencies may occur. We accounted for a pituitary dwarfism with delayed diagnosed transsphenoidal encephalocele associated with morning glory syndrome, showing the alterations found in retinography, computed tomography and magnetic resonance imaging.

RESUMO

As encefaloceles basais são entidades raras e correspondem a herniações do tecido cerebral através de um defeito do crânio, ao longo da lâmina crivosa etmoidal ou do osso esfenoidal. A rara síndrome morning glory, com alterações de fundo de olho características pode apresentar-se associada à encefalocele basal. Deficiências hormonais hipofisárias podem ocorrer. Relatamos caso de nanismo hipofisário com encefalocele transesfenoidal de diagnóstico tardio associada à síndrome de morning glory, mostrando as alterações na retinografia, tomografia computadorizada e ressonância magnética.
