3rd Ventricle Mass, Anterior

SUMMARY During water diuresis in conscious goats, noradrenaline (NA), its antagonists phentolamine, phenoxybenzamine and propranolol and also atropine were administered into the 3rd ventricle. The subsequent effects on water diuresis and on the excretion rates of Na+, K+ and Cl− were investigated. Infusion of NA into the 3rd ventricle induced a strong and significant antidiuretic response and a decrease in the Na+: K+ excretion ratio; these effects were dose-dependent. High doses of NA produced a significant increase in urinary K+ excretion. Similar results were observed after i.v. administration of arginine-vasopressin. Pretreatment with phentolamine injected into the 3rd ventricle produced a dose-dependent inhibition of the NA-induced antidiuretic effects. Phenoxybenzamine also blocked the response to NA but a dose-response relationship was not apparent. Atropine and propranolol did not block the response to NA.

Abstract Eighteen patients with a colloid cyst of the 3rd ventricle presented to the Frenchay Hospital Neurosurgery Unit. The investigations included computed tomography (CT). Of these patients, 9 had radiographically isodense cysts that caused considerable diagnostic difficulties, being described only as an anterior 3rd ventricular space-occupying lesion and lateral ventricular dilatation in all but 2 cases. The clinical findings are described and the CT appearance is discussed. The new use of ventriculoscopy may resolve the problem rapidly; ventriculoscopy made the diagnosis in 5 cases and confirmed a CT diagnosis in 3 others. (It has also confirmed the diagnosis in 2 cases of hyperdense cysts.) Lately, it has been possible to aspirate the cyst contents endoscopically or, if the colloid is too viscous, to remove it with endoscopic rongeurs. After either of these procedures, the cyst wall can be coagulated with diathermy endoscopically. The method is described, and the advantages over other investigations and treatment are discussed.

Abstract The results of endoscopic biopsy in 21 cases of intraventricular tumor are presented. The details of the equipment are given. Of the 21 tumors biopsied, there were 9 in the lateral ventricle, 2 in the thalamus, 6 in the anterior portion of the 3rd ventricle, and 4 in the pineal region. A correct histological diagnosis was made in 11 cases (52.4%). No serious complications were noted. The value of the procedure is discussed.

Abstract Two patients with xanthogranuloma of the 3rd ventricle are described. In each instance the tumor obstructed the interventricular foramina and caused dilatation of the lateral ventricles and signs of increased intracranial pressure; computerized tomography demonstrated the dense, nonenhancing lesion in the anterior 3rd ventricle. The pathogenesis of these rare tumors is discussed. These cases affirm the need to consider xanthogranuloma in the differential diagnosis of anterior 3rd ventricle tumors in adults.

Abstract The authors review their experience with 21 cases of intraventricular cysticercosis, which corresponded to 28% of all cases of neurocysticercosis in their department during an 18-month period. The surgical approach depends on the cyst's location; one uses the transcortical microsurgical approach to reach the lateral ventricles, the transcortical or transcallosal approach to reach the 3rd ventricle, and direct exploration to reach the 4th ventricle. Cysticercus cysts should be removed because they may produce acute or chronic hydrocephalus and, if the parasite dies within the ventricles, it will generate an inflammatory reaction with local and generalized ventriculitis, which produces irreversible neurological damage.

Abstract Five adult patients with 3rd ventricle tumors underwent a transcallosal intraventricular parafornicial approach. Pre- and postoperative cognitive reviews were conducted on all patients. Each review consisted of: (a) a standardized neuropsychological battery, (b) mental status reviews, (c) specific tests for disconnection, and (d) a personality variable, where possible. Computed tomography and magnetic resonance imaging are also presented. The three patients with colloid cysts and the two with oligodendrogliomas showed no significant postoperative cognitive deficits compared to the preoperative review. These additional subtle neuropsychometric measures, along with the methodological advantage of preoperative review, support a parafornicial approach where indicated to preserve cognitive abilities.
