Fourth ventriculoceles with extracranial extension
Insights
This study reviews cystic suboccipital masses in infants, finding surgical treatment leads to better long-term outcomes than occipital encephalocele. Early diagnosis and intervention are crucial for these rare congenital brain lesions.
Area of Science:
- Pediatric Neurosurgery
- Developmental Neuroscience
- Radiology
Background:
- Cystic suboccipital masses communicating with the fourth ventricle are rare congenital brain malformations.
- These lesions can be misdiagnosed as occipital encephaloceles, a more common condition.
- Understanding their unique characteristics is crucial for appropriate management.
Abstract:
The radiographic features and long-term clinical outcome in three patients who presented at birth with a cystic suboccipital mass in direct communication with the fourth ventricle are reviewed. The pathological findings in a fourth infant who died are also discussed. All surviving infants were treated with cyst excision and diversion of cerebrospinal fluid. The prognosis in these children, followed from 6 to 20 years, surpasses that of the more common occipital encephalocele, for which this entity could be mistaken. The morphogenetic implications relative to more common congenital lesions in this location are discussed.
