A case of Dandy-Walker malformation associated with occipital meningocele, microphthalmia, and cleft palate
1Department of Neonatology, Japanese Red Cross Medical Center, Tokyo.
Abstract:
We present a case of Dandy-Walker malformation associated with occipital meningocele, microphthalmia, and cleft palate. Small numbers of cases of Dandy-Walker malformation with occipital meningocele have been described in the literature, but to our knowledge, non of these also had microphthalmia or cleft palate. This association suggests that time of intrauterine origin of Dandy-Walker syndrome was in the sixth or seventh embryonic week. In the diagnosis, both CT cisternography and direct neurosonography over the occipital meningocele was useful for the demonstration of a posterior fossa cyst which communicated with the fourth ventricle and the occipital meningocele.
Insights
This case study details Dandy-Walker malformation with occipital meningocele, microphthalmia, and cleft palate. The rare combination suggests an early embryonic origin, aiding diagnostic insights.
Area of Science:
- Neuroscience
- Developmental Biology
- Medical Case Reports
Background:
- Dandy-Walker malformation is a congenital brain defect.
- Occipital meningocele is a rare neural tube defect.
- Previous reports rarely associate Dandy-Walker malformation with occipital meningocele.
Observation:
- A unique case presented Dandy-Walker malformation concurrently with occipital meningocele, microphthalmia, and cleft palate.
- This specific combination has not been previously documented in medical literature.
- The co-occurrence suggests a critical developmental window during the sixth or seventh embryonic week.
Findings:
- CT cisternography and direct neurosonography proved effective diagnostic tools.
- These imaging techniques visualized the posterior fossa cyst communicating with the fourth ventricle and the occipital meningocele.
- Confirmed the complex structural abnormalities in the developing fetal brain.
Implications:
- The findings refine the understanding of Dandy-Walker malformation's developmental timeline.
- Highlights the importance of comprehensive evaluation for associated congenital anomalies.
- Suggests potential genetic or environmental factors influencing early neurodevelopment.
