Obstructive Colloid Cyst of the Third Ventricle

BACKGROUND : Colloid cysts are one of the rare brain tumours and are mostly located in the anterosuperior portion of the third ventricle, between the fornix and surround of Foramen of Monroe. OBJECTIVES: Ÿ 1.To review the demographic information & analyse clinical manifestations of patients presenting with colloid cyst of third ventricle. Ÿ 2.To analyze the advantages and disadvantages of various surgical approaches Ÿ 3.To assess the surgical outcome in colloid cyst patients operated by any method. MATERIALS AND METHODS: A retrospective study was performed on 16 patients who presented with a colloid cyst and underwent surgery at the Department of Neurosurgery, King George Hospital, Andhra Medical College between 2013-2018. They were evaluated based on clinical ndings and imaging features, surgical approaches used for resection and their outcomes. RESULTS: Sixteen cases of colloid cyst of the third ventricle were operated upon between 2013-2018. There were seven male and nine female patients with their ages varying between 9 and 62 years old. Nine patients were operated on by using a transcortical trans-ventricular approach, four using the anterior trans-callosal approach and, three patients by using an endoscopic approach. In all patients, complete excision of the lesions was achieved. CONCLUSION: Colloid cysts, though benign, present surgical challenges because of its deep midline location. Complete excision of the colloid cyst carries an excellent prognosis. Surgery is a safe and effective treatment option for this benign lesion.

Microsurgical Resection

Objectives: Cerebrospinal fluid shunting or microsurgical resection of the colloid cysts of the third ventricle have long been a standard treatment. The emergence of neuroendoscopy has lead to its application in various neurosurgical problems. Colloid cyst of the third ventricle is one such pathology where endoscopic treatment has been performed with great clinical success during the past decade. We now Although considered less efficacious than microsurgical excision endoscopic excision is less invasive and much simpler.Objectives: (1) to assess the extent of excision (2) to assess the morbid anatomy of the colloid cyst (3) to assess the risk of complications (4) to assess the functional outcome. Period: Eight years (Jul 2001-June 2009) Materials and Methods: Endoscopic resections of 15 colloid cysts of the third ventricle with obstruction of Foramina of Monroe in all cases. Results: Total removal was achieved in 10 (66.7%) cases. In 5 (33.3%) patients the colloid material was evacuated completely while the remnant of the capsule adherent to its origin was left behind. Two (13.3%) patients developed meningitis one week postoperatively and one diedsubsequently. Nine (60%) patients had excellent recovery as the symptoms were relieved during a period of 3 to 24 months. Five (33.3%) of the total patients required ventriculoperitoneal shunt for obstructivey drocephalus which developed with in 2 weeks after surgery. One out of the total number of patients deteriorated postoperatively on the existing neurological deficit. There has not been any recurrence until now with subtotal excision of the capsule. Conclusions: Keyhole surgery under endoscopic visual control offers an alternative, very effective minimally invasive approach for the excision of colloid cyst of the third ventricle and is likely to replace microsurgical resection as a standard procedure.

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.

ABSTRACTIntracranial dermoid cyst and colloid cysts of the third ventricle are rare benign congenital lesions of early adulthood. Both lesions are thought to be congenital in origin however association is rare. Only one case of this association has been reported. We report a 22-year-old male with suprasellar dermoid cyst and colloid cyst of the third ventricle presenting simultaneously. Embryogenesis of this association has been discussed.

Study Support

Abstract Objective: To further assess the safety and long-term efficacy of endoscopic resection of colloid cysts of the third ventricle. Methods: A retrospective review of a series of 35 consecutive patients (18 male, 17 female) with colloid cysts treated by endoscopic surgery was undertaken. Results: The mean patient age was 32.4 years (range, 11–54 yr). Headache was the most common presenting symptom (22 patients). The average tumor size was 18 mm (range, 3–50 mm). The endoscopic technique could not be completed in six patients, necessitating conversion to an open craniotomy and a transcortical approach to the colloid cyst. All patients had histologically confirmed colloid cysts of the third ventricle, and complete resection of the lesion was confirmed macroscopically and radiologically in all patients. There were no deaths. Two patients developed aseptic meningitis without any permanent sequelae. One patient developed unilateral hydrocephalus attributable to obstruction of the foramen of Monro, which was treated with endoscopic septum pellucidotomy. The median follow-up period was 88 months (range, 10–132 mo). There was one asymptomatic radiological recurrence. No seizures occurred after surgery. Conclusion: The results of this study support the role of endoscopic resection in the treatment of patients with colloid cysts as a safe and effective modality. In some cases, conversion to an open procedure may be required. Additional follow-up will be required to continue to address the duration of lesion-free survival.
