Encephalocele is a rare disorder where the skull bones do not fully close, creating an opening. Brain tissue, fluid, and membranes protrude out in a sac. It is usually diagnosed prenatally at 8 weeks and is visible on the head. Surgery is required to close the opening and prevent complications like hydrocephalus. After surgery, patients require monitoring and rehabilitation as they may experience issues like developmental delays, seizures, or paralysis.
