Atretic Cephalocele: Report of Two Cases

ABSTRACT

In cases of meningoencephalocele, brain tissue, which is enveloped by the meninges and cerebrospinal fluid, herniates through the skull defect. Atretic cephalocele, on the other hand, is a congenital malformation in which small meningeal and vestigial glial tissue herniates through this defect; a benign nodular lesion is found near the midline of the scalp. Atretic cephalocele can occur in the parietal or occipital area; in cases involving the latter, the prognosis is poor. We report the radiologic findings of two cases of atretic cephalocele confirmed by surgery and pathologic findings.
