Q01.0

Clinical Causes: Genetic mutations or chromosomal abnormalities Environmental factors during pregnancy, such as exposure to teratogens Disruptions in neural tube development early in fetal growth Family history of neural tube defects Insufficient maternal folic acid intake during pregnancy

Key Symptoms: Visible protrusion or swelling on the forehead or scalp Partial or complete protrusion of brain tissue and membranes through the skull opening Possible associated anomalies like cleft lip or palate Hydrocephalus (accumulation of fluid in the brain) Developmental delays or neurological impairments depending on severity Seizures in some cases Signs of increased intracranial pressure, such as vomiting or irritability

Diagnosis Path: Diagnosis of frontal encephalocele is primarily made through detailed imaging studies. An ultrasound may detect skull defects during pregnancy. Postnatally, magnetic resonance imaging (MRI) and computed tomography (CT) scans provide detailed visualization of the brain and skull, confirming the presence and extent of the encephalocele. Physical examination of the newborn, noting the location and size of any protrusion, is also critical. Delivery in a specialized center is often recommended for immediate assessment and planning for surgical intervention.

Treatment Protocols: The mainstay of treatment for frontal encephalocele is surgical repair. The procedure involves repositioning or removal of herniated brain tissue and closure of the skull defect to prevent infections and further neurological damage. Preoperative evaluations include detailed imaging to guide surgical planning. Additional supportive therapies may be necessary, especially if associated conditions like hydrocephalus are present, which may require ventriculoperitoneal shunt placement. Postoperative care involves monitoring for complications, managing neurological function, and involving multidisciplinary teams including neurosurgeons, neurologists, and developmental specialists. Long-term follow-up helps address developmental delays or disabilities that may arise.
