Direct Inspection with Dual Endoscope Technique via Bilateral Transforaminal Approach Leading to Complete Resection of Recurrent Colloid Cyst of the Third Ventricle

Colloid cysts are histologically benign lesions whose primary goal of treatment should be complete resection to avoid recurrence and sudden death. Open surgery is traditionally considered the standard approach, but, recently, the endoscopic technique has been recognized as a viable and safe alternative to microsurgery. The endoscopic approach to colloid cysts of the third ventricle is usually performed through the foramen of Monro. However, this route does not provide adequate visualization of the cyst attachment on the tela choroidea. The combined endoscopic transforaminal-transchoroidal approach (ETTA), providing exposure of the entire cyst and a better visualization of the tela choroidea, could increase the chances of achieving a complete cyst resection. Between April 2005 and February 2011, 19 patients with symptomatic colloid cyst of the third ventricle underwent an endoscopic transfrontal-transforaminal approach. Five of these patients, harboring a cyst firmly adherent to the tela choroidea or attached to the middle/posterior roof of the third ventricle, required a combined ETTA. Postoperative MRI documented a gross-total resection in all 5 cases. There were no major complications and only 1 patient experienced a transient worsening of the memory deficit. To date, no cyst recurrence has been observed. An ETTA is a minimally invasive procedure that can allow for a safe and complete resection of third ventricle colloid cysts, even in cases in which the lesions are firmly attached to the tela choroidea or located in the middle/posterior roof of the third ventricle.

Colloid Cysts

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.

Background. Third ventricle tumors are uncommon and account for only 0.6 - 0.9% of all the brain tumors7. In 1921, Dandy was the first neurosurgeon who successfully removed a colloid cyst from the third ventricle through a posterior transcallosal approach. Despite their unfavourable locations, these tumours can be removed successfully by proper knowledge of anatomical landmarks and by choosing the appropriate approach. Methods. We performed a retrospective analysis of all patients (17 patients) who underwent surgery for anterior third ventricular masses between March 2018 to March 2020 in the Dr Ram Manohar Lohia Institute of Medical Science Lucknow, Uttar Pradesh. Results: The most common symptom in our cases was headache, which was present in all (100%) patients, nausea/vomiting in 7 (41%), history of recurrent episodes of drop attacks in 4 (23%), h/o seizure in 2 (11.7%), visual disturbance in 1 (5.4%), memory disturbance in 1 (5.4%) and urinary incontinence in 1 (5.4%) patient. 6 patients were operated with transcallosal-transforaminal approach, 1 patient was operated with transcallosal interforniceal approach, 3 patients were operated with transcortical-transforaminal approach, 1 patient was operated with subfrontal translamina terminalis approach, 1 patient was operated with transcallosal-transchoroidal approach, 5 patients were operated with endoscopically. Gross total excision was achieved in 15 (88%) patients while in 2 (11.7%) patients subtotal resection was done due to their adherence to choroid plexus and optic chiasm. The most common post-operative complication was endocrine dysfunction in the form of diabetes insipidus. Conclusions. Anterior Third ventricular tumours are mostly benign and best treatment modality is surgical resection. When we analyzed the results of various approaches, we found that despite their unfavourable location, the results were satisfactory for different tumours of different location in the anterior third ventricle, when treated with the carefully planned microsurgical or endoscopic approach with proper knowledge of anatomical landmarks.

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.
