Interfrontal encephalocele: a rare feature of forehead in hydrocephalic myelomeningocele patients. Clinical feature, probable mechanisms, and management

Objective Myelomeningocele is a complex central nervous system malformation mostly associated with other neural and extraneural anomalies. A rare special feature of the forehead and skull was observed in myelomeningocele. Here, we present several patients with myelomeningocele, severe hydrocephalus, and interfrontal encephalocele accompanied by metopic suture widening and abnormally shaped frontal bones.
