Abstract:
Neuronal migration anomalies form a spectrum of congenital brain malformations with a variety of clinical manifestations. The widespread use of MRI in the investigation of neurological symptoms, and particularly in the imaging of epilepsy, has made the correct recognition and interpretation of these disorders important. This pictorial summary describes the typical clinical features and the MR appearances of this group of conditions. For a more detailed review which includes pathological correlation, the reader should refer to an excellent article by Barkovitch and colleagues (Barkovitch A.J., Gressens P, Evrard P. Formation, maturation and disorders of brain neocortex.
Insights
Neuronal migration anomalies are congenital brain malformations with diverse symptoms. Understanding their MRI features is crucial for diagnosing neurological disorders, especially epilepsy.
Area of Science:
- Neuroscience
- Radiology
- Developmental Biology
Background:
- Neuronal migration anomalies encompass a range of congenital brain malformations.
- These conditions present with varied clinical manifestations.
- Accurate recognition is vital due to the increasing use of MRI in neurological assessments, particularly for epilepsy.
Purpose of the Study:
- To describe the typical clinical features of neuronal migration anomalies.
- To illustrate the characteristic magnetic resonance (MR) imaging appearances of these disorders.
Main Methods:
- This is a pictorial review.
- It focuses on the MR imaging findings associated with neuronal migration anomalies.
Main Results:
- The abstract outlines the key clinical presentations.
- It details the expected MR imaging characteristics for this group of conditions.
Conclusions:
