Apert's syndrome (AS) is a rare congenital malformation characterized by distinctive clinical manifestations such as syndactyly of the extremities and midface retrusion, which set it apart from other syndromes. This condition often presents with craniosynostosis and, less commonly, central nervous system abnormalities like encephalocele. In this report, we present a typical case of Apert syndrome with an occipital encephalocele. The infant had plagio-brachycephaly due to craniosynostosis and required urgent repair of the occipital encephalocele. At 1 month of age, we performed both the encephalocele repair and early cranioplasty for autologous bone grafting. This case underscores the importance of early diagnosis and surgical interventions in Apert's syndrome cases with encephalocele.
