Congenital brain malformations comprise a spectrum of disorders that result from a variety of causes, including genetic abnormalities, ischemia, infections, and toxic exposures. Although most cases are discovered in infancy or childhood, clinically occult abnormalities may prove to be confounding, especially if first encountered later in life on imaging examinations obtained for other indications or in the context of superimposed pathology. This review article provides an overview of congenital brain malformations because they may be encountered at all ages for general radiologists.

The recovery process following ischemic stroke is a complex undertaking involving intricate cellular and molecular interactions. Cellular dysfunction or aberrant pathways can lead to complications such as brain edema, hemorrhagic transformation, and glial scar hyperplasia, hindering angiogenesis and nerve regeneration. These abnormalities may contribute to long-term disability post-stroke, imposing significant burdens on both families and society.

In order to study this gene and its association with these phenotypes, our lab recently created a heterozygous mutant mouse inspired by a clinically relevant mutation. This model recapitulates several of the physical and neurologic abnormalities seen in humans with MYT1L syndrome, such as weight gain, microcephaly, and behavioral disruptions.

Germline genetic variants have been identified in congenital disorders of glycosylation and somatic variants have been linked to intractable epilepsy associated with malformations of cortical development. However, the functional consequences of these pathogenic variants on brain development and network integrity remain elusive.

These compartments exhibit distinct anatomical, neurochemical, and pharmacological characteristics and have separable roles in motor and mood functions. Little is known about the functions of these compartments in humans.
