Subcortical band heterotopia (DCX), seizures, developmental delay, ADHD. New choreiform-like movements and dystonia. There is extensive band-like subcortical grey-matter signal intensity bilaterally with associated mildly anomalous and simplified cerebral gyration pattern and enlarged ventricles, particularly the posterior lateral ventricles. There is also a prominent retrocerebellar space and diminutive appearance of the inferior cerebellum, particularly the vermis. There is a cystic pineal gland that measures up to 11 mm. The corpus callosum and pituitary gland are intact. There is no herniation or midline shift. The major cerebral flow voids appear to be grossly intact. The orbits are unremarkable. There is mild diffuse paranasal sinus mucosal thickening.
