Parietal atretic cephalocele: Associated cerebral anomalies identified by CT and MR imaging

We describe a case of atretic cephalocele (AC) characterized by the presence of various cerebral anomalies of different midline structures. In our patient the presence of a parietal AC was associated with an embryonic position of the straight sinus, fenestration of the superior sagittal sinus, an abnormal insertion of the cerebellar tentorium with prominence of the superior cerebellar cistern and a septum pellucidum cyst. These findings, associated with AC, could lead to a worse prognosis with regard to neurodevelopmental milestones. This suggests that even if AC is a benign lesion, a complete evaluation of the brain structures should always be performed in these young patients.
