Patient Data

Age: 60
Gender: Male

note the cortical thickening in right frontal lobe and insula.

nodular heterotopia are also seen. the entire cortical mantle is involved upto periventricular region

Case Discussion

focal transmantle dysplasia (FTD) is also known as Taylor's dysplasia

It is a distinct entity as it involves not only the cortex but also the underlying white matter upto periventricular region. Frontal location is most common, on HPE they usually show balloon cells.

this is in contrast to non balloon cell dysplasia that are more common in temporal lobe.
