Overview
Hydranencephaly is a severe congenital disorder characterized by the replacement of most of the cerebral hemispheres with cerebrospinal fluid, leaving only a thin membrane covering the brain surface, typically associated with significant neurological impairment 1.Diagnosis
Ultrasound findings: Massive intracranial hemorrhage diagnosed in utero can evolve into hydranencephaly, monitored via serial ultrasounds 1.
Imaging: MRI or CT may confirm the absence of brain parenchyma and presence of fluid-filled spaces 1.
Clinical correlation: Often diagnosed alongside other congenital anomalies, such as those seen in Roberts syndrome 2.Management
Supportive care: Focus on managing symptoms and supportive measures for associated complications (respiratory, feeding difficulties) 1.
Multidisciplinary approach: Involvement of pediatric neurology, neonatology, and rehabilitation specialists 1.
No specific pharmacological treatment: No curative pharmacological interventions exist for hydranencephaly 1.Special Populations
Pregnancy: In utero diagnosis possible via ultrasound, monitoring progression to hydranencephaly 1.
Pediatrics: Early recognition crucial for planning supportive care and addressing associated congenital anomalies 12.Key Recommendations
Perform serial ultrasounds during pregnancy for fetuses with suspected intracranial hemorrhage to monitor for hydranencephaly development (Evidence: Moderate 1).
Integrate multidisciplinary teams for comprehensive care in neonates diagnosed with hydranencephaly (Evidence: Expert opinion 1).
Screen for and manage associated congenital anomalies in patients with hydranencephaly, such as those seen in syndromes like Roberts (Evidence: Moderate 2).References
