MRI of a family with focal abnormalities of gyration.

Focal abnormalities of gyration (FAG) are developmental disorders that may occur in isolated patients or, as in the case being reported, as part of a familial disorder. Analysis of individuals in a family spanning three generations was carried out using MRI. Abnormalities, present in all members of generations II and III, included focal cortical dysplasia (three patients), focal cortical infolding (two patients) and schizencephaly (one patient); associated minor anomalies, such as white matter abnormalities, were seen in the remaining three members of generations II and III. MRI recognition of FAG in the family being reported proved useful in defining their phenotypical expression and providing proper counselling for individual family members.

Spontaneous hematomas caused by microangiomatosis of the basal ganglia. Presentation of two cases in the newborn period.

We present 2 cases of tumors of the gray basal nuclei with intraventricular hemorrhage and secondary hydrocephalus. Because of the patients' ages, the absence of traumatic antecedents and the angiographic characteristics, the findings were diagnosed as gliomas. In both cases, the existence of hematomas provoked by microangiomatosis was proved after the operation. The differential diagnostic between these two entities is discussed.

Clivus ependymoma.

A 8-month-old girl had an ependymoma in the clivus, 2 X 6 cm in size, connected with the fourth ventricle by a cord of tissue 0.5 cm thick. There were no indications to make us suspect the origin of the tumour in the fourth ventricle, or that it was a case of ependymoma.

Successful surgical treatment of an odontogenic ossified craniopharyngioma. Case report.

A large, highly ossified craniopharyngioma was diagnosed and surgically treated in a 2-year-old girl. About 20 teeth were macroscopically identified in the operative specimen, some of them totally developed, complete with crown and root. Pathological study established the diagnosis of craniopharyngioma with formation of teeth. Only five cases have been reported previously, and only one patient survived the operation. The patient is alive 3 years after surgical treatment. Radiotherapy was not used.

Radiological Diagnosis of Periventricular and Subcortical Leukomalacia.

Nine newborn infants with histories of perinatal asphyxia are presented. The pneumoencephalographic findings which led to the diagnosis are typical and constant. They include marked subcortical atrophy with rounded, dilated, and undisplaced lateral ventricles. Cystography with 3 cc of air demonstrated multiple subcortical and pareventricular cavities, without communication with the ventricular system, but with the typical honeycomb appearance of paraventricular and subcortical leukomalacia described in postmortem findings. The CT findings are typical, and provide the location of the cavities as well as their density.

Occlusion of the cerebral arteries in Recklinghausen's disease.

Two children, aged 18 months and 6 years, who had Recklinghausen's disease, had occlusion of cerebral arteries. One child had no motor deficit but the other had right hemiparesis and partial occlusion of the left posterior cerebral artery, a fact not found in the literature.

Congenital atresia of the foramen of Monro.

Two cases of congenital atresia of the foramen of Monro are described, one 8 days old and the other 2 months old. Both are associated with a parieto-occipital paraventricular diverticulum and spontaneous ventriculostomy with the passing of the cerebrospinal fluid to the posterior fossa and the formation of a cyst in the supracerebella region which compressed and displaced the structures of the posterior fossa.

Spontaneous ventriculostomy and ventricular diverticulum.

Four cases of ventricular diverticulum are presented, 2 with spontaneous ventriculostomy. In 2 patients, the cause was monoventricular hydrocephalus through congenital stenosis of the foramen of Monro, with paraventricular diverticula and spontaneous ventriculostomy. Both patients had a cystic space in the quadrigeminal and supracerebellar cistern. In one patient during pneumoencephalography, the ventricular diverticulum filled via the ventriculostomy. The other 2 patients had congenital stenosis of the Sylvian aqueduct with the formation of a large supratentoria cyst connecting with the posterior part of the third ventricule.
