Summary
This study reports hereditary nodular heterotopia with mega cisterna magna, a rare brain malformation. The condition appears to be inherited as a dominant trait, affecting multiple family members.
Area of Science:
- Neurology
- Genetics
- Radiology
Background:
- Hereditary nodular heterotopia is a rare congenital brain malformation.
- Mega cisterna magna is an enlargement of the cisterna magna, a space at the back of the brain.
- The co-occurrence of these two conditions has not been previously reported.
Purpose of the Study:
- To report the first case of hereditary nodular heterotopia accompanied by mega cisterna magna.
- To describe the neuroimaging findings in this unique presentation.
- To investigate the potential genetic inheritance pattern.
Main Methods:
- Magnetic resonance imaging (MRI) was used to visualize brain structures.
- Clinical data from affected family members were reviewed.
- Family history was analyzed to determine the mode of inheritance.
Main Results:
- Multiple bilateral subependymal nodules were identified on MRI, isointense to gray matter.
- The cisterna magna was significantly enlarged (mega cisterna magna).
- The condition affected a mother and her two daughters, suggesting a dominant inheritance pattern.
Conclusions:
- Hereditary nodular heterotopia can co-occur with mega cisterna magna.
- This combined presentation may represent a distinct genetic syndrome.
- Further research is needed to elucidate the genetic basis and clinical spectrum of this disorder.
