Background
The prevalence of encephalocele is estimated to be 0.8–5.0 per 10,000 live births. The most frequent encephalocele is the occipital encephalocele. It is a congenital neural tube defect characterized by the protrusion or herniation of intracranial contents through a cranial defect. The term “giant/massive/large encephalocele” is used to describe an encephalocele that is significantly larger than the size of the head.
Case description
A 2-month-old male infant presented in the neurosurgery outpatient department with one of the largest head masses over the posterior aspect since birth. The swelling was gradually progressive and developed ulceration over the swelling with intermittent cerebrospinal fluid (CSF) discharge but no associated weakness in limbs. Magnetic Resonance Imaging (MRI) brain showed a large occipital meningoencephalocele containing predominantly cyst with part of the cerebellar and occipital lobe. The surgery was planned. The sac contained CSF with the gliotic occipital lobe. The sac and gliotic brain tissue was excised. He had an uneventful postoperative course.
Conclusion
Surgery serves several functions, including reducing the torque and weight of the head to allow for more normal motor development, removal of the thin, leaking scalp and dural closure to prevent CSF leak and subsequent infection, and improving the cosmetic and social issues that the child and family may have to endure.
