Ulegyria refers to a shrunken and flattened cortex usually due to global hypoxic ischemic injury in term infants, centering on the deepest portion of gyri, usually in the parasagittal region. It is here that perfusion is most tenuous and, therefore, most susceptible to ischemic damage 1.
Clinical presentation
It is one of the leading causes of posterior cortex epilepsy 2.
Radiographic features
MRI
A mushroom-shaped morphology of gyri is the characteristic appearance of ulegyria 2.
