Summary
Congenital brain malformations are birth abnormalities. This study offers a streamlined approach combining imaging and genetic testing for accurate diagnosis and management.
Area of Science:
- Neuroscience
- Developmental Biology
- Medical Imaging
Background:
- Congenital brain malformations are present at birth, stemming from embryonic or fetal developmental disruptions.
- Clinical signs are nonspecific, including developmental delay, hypotonia, and epilepsy.
- Early diagnosis and management planning are crucial.
Purpose of the Study:
- To present a streamlined workflow for radiologic phenotyping and genetic evaluation of brain malformations.
- To correlate neuroimaging findings with embryology and molecular pathogenesis.
- To provide up-to-date ontologies and literature references for clinical practice.
Main Methods:
- Review of clinical workflow for brain imaging and genetic testing.
- Development of an imaging-based etiologic classification (malformative, destructive, migrational).
- Detailed discussion of specific radiologic ontologies.
Main Results:
- A structured approach to classifying brain malformations based on imaging features.
- Correlation of imaging findings with underlying embryological and molecular mechanisms.
- Integration of imaging and genetic data for diagnosis.
Conclusions:
- A combined imaging and genetic approach facilitates early and accurate diagnosis of congenital brain malformations.
- Radiologic phenotyping and genetic evaluation are essential for effective management planning.
- This framework aids in understanding the pathogenesis of diverse brain abnormalities.
