case_images: Sagittal plane MRI shows a small hypoplastic adenohypophysis measured at 3.3 mm of height. There is an absent pituitary stalk. There is likely an ectopic posterior pituitary gland at the medial eminence with loss of its normal spontaneous hyperintense T1 signal.

case_images: Axial plane MRI T2 fluid-attenuated inversion recovery shows one heterotopic grey matter-lined cleft measuring around 2 cm extending from the right parietal lobe toward the right lateral ventricle. There is diminished white matter volume noted at this level.

case_images: Moreover, a large area of markedly increased cortical thickness in the right parietal region, centred at the cortex of the Sylvian fissure and most pronounced in the posterior aspect, was highly suggestive of FCD (figures2  3).
case_images: Axial plane T2 shows multiple nodular heterotopic grey matter lesions, with small gyri noted within the white matter of the right insular area (frontal, parietal and temporal operculum) extending to the right supramarginal gyrus.
