title: Ventricular diverticulum at the posterior horn of the lateral ventricle presenting as aplasia cutis congenita.
abstract: Non-communicating hydrocephalus can cause rupture of the lateral or third ventricle, generally in the medial wall of the trigone or the posterior wall of the third ventricle, resulting in a cystic lesion known as ventricular diverticulum. In this paper, we describe a rare case of ventricular diverticulum located in the posterior horn of the lateral ventricle and expanding to bulge with a convexity reaching into the subdural space in a neonate. Aplasia cutis congenita and a bone defect were also present in the same neonate. Early surgical repair of the scalp defect and ventriculoperitoneal shunting were performed. In addition to illustrating the rare co-existence of a ventricular diverticulum at the posterior horn of the lateral ventricle and aplasia cutis congenita in a neonate, this case also offers new insights into the pathogenesis of these congenital anomalies.
