A Case Report of Postoperative Cystic Hydrocephalus Following Duroplasty and Scalp Reconstruction in Neonatal With Aplasia Cutis Congenita and Extensive Craniodural Defect.

In severe cases, the defect may extend to the skull and dura mater, exposing intracranial structures and increasing the risk of infection, hemorrhage, and venous sinus injury.

Extensive aplasia cutis congenita with both cranial and dural defects remains exceedingly rare, and optimal management strategies are not well established.

The lesion was covered by a thin membranous tissue with visible brain pulsation and exposure of the superior sagittal sinus (sagittal sinus).

At 24-month follow-up, the patient achieved normal developmental milestones with a good cosmetic outcome.
