✓ Two cases of paraventricular cavernous angiomas are presented. In one, the cavernous angioma was found in the right wall of the fourth ventricle, and in the other in the right thalamus encroaching upon the third ventricle. Both patients had onset of symptoms suggesting a tumor. Good results were obtained by the microsurgical approach to these malformations. The computerized tomography findings typical of cavernous angiomas are reviewed.

✓ Two cases of cryptic vascular malformation that were not demonstrated by cerebral angiography were detected by computerized tomography. One of these patients had a cavernous angioma in the fourth ventricle with recurrent subarachnoid hemorrhages, and the other harbored a small arteriovenous malformation and intracerebral hematoma. The usefulness and limitations of computerized tomography in the identification of cryptic vascular malformations are discussed.

✓ A method for visualizing the third ventricle, aqueduct of Sylvius, and fourth ventricle with methylglucamine iothalamate 60% (Conray) in infantile hydrocephalus is described. Only a small amount of contrast medium is necessary to visualize these structures. This procedure has been performed in 47 infants from 7 days to 3 years of age, and has been proved simple, safe, and valuable in the diagnosis of lesions around the third and fourth ventricles.

Sodium And Potassium

ABSTRACT Two artificial cerebrospinal fluid mixtures, one having a higher than normal sodium, but lower than normal potassium content, the other having a lower than normal sodium, but higher than normal potassium content, were perfused alternately through the cerebral ventricular system of seven dogs, from the right lateral ventricle and down through the third ventricle, aqueduct and fourth ventricle. During this procedure blood was collected through the adrenal vein and the concentration of cortisol (11β, 17,12-trihydroxy-pregn-4-eme-3,20-dione), cortisone (17,21-dihydroxypregn-4-ene-3,11.20-trione), corticosterone (11β,21-dihydroxy-pregn-4-ene3,20-dione). compound S (11-dihydroxy-3,20-dioxo-pregn-4-en-18-al) and aldosterone (11β.21-dihydroxy-3,20-dioxo-pregn-4-en-18-al) determined. A gradual and marked increase in the secretion of all the cortical compounds was observed during the procedure. This pattern was not altered by changing from one of the artificial cerebrospinal fluid mixtures to the other.

✓ A 10-year-old boy presented with acute obstructive hydrocephalus caused by the impaction of a calculus on the cerebral aqueduct. The calculus migrated from the third ventricle to the fourth ventricle after ventricular drainage and right ventriculoperitoneal shunt placement had been performed. The nature and origin of the calculus could not be determined, although its release from the choroid plexus in the lateral ventricle is highly possible.

Neuroradiological Imaging

✓ Colloid cysts are rare intracerebral lesions that are preferentially encountered within the third ventricle. There are only a few reports in which colloid cysts are described in other locations such as the fourth ventricle.A symptomatic intracerebellar colloid cyst in a 45-year-old woman is described. The patient presented with headache, gait disturbance, and nausea. Neuroradiological imaging revealed compression of the fourth ventricle, hydrocephalus, and an intracerebellar cystic lesion measuring 4 × 5 cm that had a small peripheral solid portion. The cyst was successfully removed via a paramedian suboccipital approach. Postoperatively, the patient recovered quickly.The findings in the present report represent an additonal example of the broad spectrum of cystic lesions encountered in the cerebellum.

✓ Colloid cysts of the third ventricle are described in middle-aged twin brothers. One of them presented with recurrent attacks of headache. In this patient the cyst had reached a size large enough to obstruct the cerebrospinal fluid pathway, resulting in hydrocephalus. The twin brother, although asymptomatic, was suspected of the anomaly and investigated because of the similarity of his ocular signs. The diagnosis was confirmed by computerized tomography in both the patient and his brother. The latter proved to have a smaller colloid cyst situated anteriorly in the third ventricle with no obstructive hydrocephalus. The patient was successfully operated on, while the brother is still under observation. Both brothers have had bilateral cataracts, retinal detachments, and left lateral rectus palsies. The familial occurrence of colloid cysts and their association with these ocular findings have apparently not been described before.

✓ A case is presented of a solitary primary extracerebral mixed glioma occurring in the right suprasellar and parasellar region of a 49-year-old woman who had bilateral temporal hemianopsia for 3 months. At craniotomy, the well demarcated outline and extracerebral location of the tumor suggested that it was a meningioma. However, its gliomatous nature was confirmed by identification of glial fibrillary acidic protein (GFAP) in the tumor cells. Review of nine reported solitary primary intracranial extracerebral gliomas, including the present case, revealed that they tended to occur in the third to fifth decades of life, in patients with an average age of 42½ years, and without sexual predilection. All were supratentorial with a tendency to be situated in the vicinity of the Sylvian fissure. Only the glioma in the present case was at the cranial base. They were diagnosed as three astrocytomas, two glioblastomas, two oligodendrogliomas, one astroblastoma, and one mixed glioma. A suggestion is made that all these gliomas arose primarily from heterotopic neuroglia in the leptomeninges.
