Status marmoratus
Status marmoratus is a congenital condition due to maldevelopment of the corpus striatum associated with choreoathetosis, in which the striate nuclei have a marble-like appearance caused by altered myelination in the putamen, caudate, and thalamus. This results from acute total asphyxia in the basal nucleus of full-term infants. It is associated with athetoid cerebral palsy and spastic quadriplegia.
