    Notes: Summary A comparative study of intracranial imaging and brain pathology in cases of trisomy 18 and 13 was performed. Computed tomography (CT) and ultrasonography (US) revealed disproportional dilatation of the lateral ventricles, a wide Sylvian fissure and a large extracerebellar space with a small cerebellum in each case. In addition, it was characteristic that the occipital poles of the cerebrum protruded in the infero-posterior direction in trisomy 18, and the pontine basis was relatively wide in trisomy 13. The brain pathology in trisomy 18 and 13 demonstrated that the large extracerebellar space is due to the cerebellar dysplasia and protruding occipital poles, the wide Sylvian fissures due to the temporal lobes or external capsular dysplasia, and the relatively wide pontine basis due to meningeal glioneuronal heterotopia. Thus, the characteristic intracranial image in trisomy 18 and 13 suggest microdysgenesis of the brain and might be useful for understanding the pathological structure of the central nervous system in these conditions.

    Notes: Abstract The carbohydrate-deficient glycoprotein syndrome is a newly recognised genetic disorder characterised by mental retardation, liver disfunction during infancy, cerebellar ataxia and atrophy, polyneuropathy, growth retardation, stroke-like episodes, and the appearance of carbohydrate-deficient fractions of multiple glycoproteins in the serum. The neuroradiological findings have been known as features of olivopontocerebellar atrophy. However, whether the abnormalities in the cerebellum and brain stem progress after birth is not known. We have carried out serial CT and MRI on three Japanese patients with this syndrome at different ages. A small cerebellum, with peculiar enlargement of the cisterna magna, and a small brain stem are present in infancy and atrophy of the anterior vermis and from before backwards in the cerebellar hemispheres seem to progress throughout early childhood.
