✓ A unique case is presented of a third ventricle germinoma developing 3 years after total removal of an intrasellar teratoma. The third ventricle germinoma was not considered to be a recurrence or dissemination of the mature intrasellar teratoma but to have been transformed from multicenter germ cells present in the midline of the brain with different temporal development. The relevant literature is reviewed and the problems of management of patients with germ-cell tumors are discussed.

✓ The therapeutic strategies employed in the management of anterior third-ventricular mass lesions remain controversial. Resection by conventional craniotomy, whether via a transcallosal or transcortical approach, carries well-known risks and limitations. Alternatively, in this region traditional stereotaxy has been relegated to use with biopsy only or cyst aspiration procedures. Combining aspects of both conventional and stereotaxic techniques has allowed total removal of 12 colloid cysts in six women and six men ranging in age from 25 to 71 years. No mortality and minimal morbidity have been associated with the procedures. There has been no evidence of recurrence in an average follow-up period of 19 months. By coupling the benefits of stereotaxic precision and localization to the microsurgical management of colloid cysts, several rewards have been realized: 1) only a limited cortical dissection is needed; 2) the hazards of callosal or forniceal injury can be avoided; 3) the lesion is easily localized regardless of ventricular size; 4) hemostasis can be readily achieved with bipolar cautery or defocused laser power; and 5) most importantly, a total resection is possible with little risk to the patient. Stereotaxic microsurgical laser craniotomy provides a new option for the management of colloid cysts and other anterior third-ventricular lesions.

✓ The case history of a patient with a xanthogranuloma of the third ventricle is presented. This type of lesion formed by desquamation of epithelium is usually noted as an incidental autopsy finding in the choroid plexus of the lateral ventricles. Total removal via a transcortical transventricular route led to complete recovery. These tumors should be suspected in the geriatric population. The computerized tomography findings and a review of the literature are included.

✓ Six cases of craniopharyngioma located wholly, or largely, within the third ventricle are described; these include four adults with tumors completely within the ventricular system and two children with recurrent tumors primarily within the third ventricle. Four of these patients were operated on by a transcallosal approach. Gross total removal was possible in all patients, but two have suffered recurrence and only one is alive and tumor-free. There were no signs or symptoms present preoperatively that allowed the intraventricular nature of the neoplasm to be correctly diagnosed. Air encephalography provided definitive tumor localization in each case. Three patients died of massive gastrointestinal hemorrhage in the immediate postoperative period. The surgical technique of transcallosal approach for removal of these neoplasms is described in detail.

✓ 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.

✓ Two patients with a history of progressive unilateral neurological symptoms and signs, and evidence of obstructive hydrocephalus from a mass lesion adjacent to the third ventricle as demonstrated by pneumography, were each found to have an intracerebral hematoma secondary to remote hemorrhage from a small vascular malformation. One patient died shortly after surgical exploration and the other after ventriculography. The pathophysiology of hydrocephalus associated with a vascular malformation is discussed and the need for considering a benign cause for obstructive hydrocephalus from a mass deep in the brain substance is emphasized.

✓ Since its description by Dandy in 1922, several techniques have been used to perform third ventriculostomy under endoscopic control. Except for the blunt technique, in which the endoscope is used by itself to create the opening in the floor of the third ventricle, the other techniques require more than one instrument to perforate the floor of the ventricle and enlarge the ventriculostomy. The new device described is a sterilizable modified forceps that allows both the opening of the floor and the enlargement of the ventriculostomy in a simple and effective way.The new device has the following characteristics: 1) the tip of the forceps is thin enough to allow the easy perforation of the floor of the ventricle; 2) the inner surface of the jaws is smooth to avoid catching vessels of the basal cistern; and 3) the outer surface of the jaws has indentations that catch the edges of the opening to prevent them from slipping along the instrument's jaws. The ventricle floor is opened by gentle pressure of the forceps, which is slowly opened so that the edges of the aperture are caught by the distal outer indentation of the jaws, leading to an approximately 4-mm opening of the floor. This device has been used successfully in 10 consecutive patients.This new device allows surgeons to perform third ventriculostomy under endoscopic control in a very simple, quick, and effective way, avoiding the need for additional single-use instruments.
