Case report reveals imaging findings and successful management of neonatal Arnold-Chiari Malformation Type II, indicating the need for early intervention.
Arnold‐Chiari Malformation Type II (CM‐II) is a serious congenital hindbrain disorder marked by the displacement of the cerebellum and brainstem downwards through the foramen magnum. CM‐II is frequently linked with myelomeningocele and hydrocephalus. We present a case of a male neonate delivered through C‐section with myelomeningocele, hydrocephalus, and paralysis of the lower limbs. MRI revealed the presence of Arnold‐Chiari Malformation Type II along with dysgenesis of the corpus callosum, absent septum pellucidum, scaphocephaly, and the presence of a small syrinx. Surgical management, including ventriculoperitoneal (VP) shunt placement, was successful. This case underlines the significance of MRI in diagnosis and the necessity of the early multidisciplinary management for the improvement of neonatal outcomes.
