Abstract

The morphological findings in 12 cases of Arnold-Chiari and 3 cases of Dandy-Walker malformations are described and compared to those in 2 cases of congenital hydrocephalus of unknown origin, 1 case of isolated meningo-myelocele and 2 cases of normal newborn brains. Lesions common to both types of malformation indicate a same time-related embryogenetic defect of the roofplate of the rhombencephalon, that does not allow the inferior vermis and the choroid plexus to turn inward into the fourth ventricle.

Ventriculography with positive contrast medium in early infancy.

42 ventriculographies (PV) were carried out in infants between 10 days and 10 months of age using positive contrast medium. Indications, technique of PV and complications are discussed; PV is compared with CT and it is concluded that PV is a simple method of clarifying the causes of a macrocephalus in infancy without great technical effort and that the roles of CT and PV are valuable diagnostic modalities which are complementary.

Arnold-Chiari malformation--some otoneurological features.

Arnold-Chiari malformation was diagnosed in five patients with vertigo. Four were of anatomical type I. A case report is given of one patient who presented features of a unilateral cerebellopontine angle lesion. Downward beating vertical nystagmus was an important finding in three of the five patients. Other clinical and radiological features of the condition are discussed.

Ganglioglioma of the medulla oblongata.

A patient with signs and symptoms suggestive of symptomatic Arnold-Chiari malformation was encountered. Neuroradiologic investigation revealed the presence of a medullary tumor, which later proved to be a ganglioglioma. A review of the literature suggests that this presentation is typical of medullary gangliogliomas. It is proposed that the pathophysiology of this lesion renders it amenable to decompressive therapy via suboccipital craniotomy.
