“…Patient outcomes were classified as excellent (IV), good (III), poor (II), or dead (I), according to the method used by Nitta and Symon. 51 Endoscopically treated patients had a 97.5% favorable outcome; whereas microsurgically treated patients had a 91.0% favorable outcome (p=0.006). Importantly, there was a 3.0% peri-operative mortality associated with microsurgical resection, compared to no deaths in the endoscopic group.…”

Colloid cysts of the third ventricle represent about 0.5-2 percent of intracranial tumors.1,2 Although uncommon, they are an important clinical entity because of their ability to cause cerebrospinal fluid (CSF) obstruction and sudden death. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] In one population-based study, one third of patients with symptomatic colloid cysts presented with acute neurological deterioration, underscoring the need for their treatment. There has been some debate over the optimal management of colloid cysts over the past few decades. Management options include CSF diversion procedures (e.g. ventriculo-peritoneal ABSTRACT: Objective: Endoscopic resection of colloid cysts has been performed as an alternative to microsurgical resection and stereotactic aspiration since 1982. To date, there are limited published studies comparing these procedures. In this study, we present the largest series of endoscopic resections published to date and compare outcomes to a cohort of microsurgical resections performed at the same institution. Methods: A retrospective chart review was conducted for all patients in the Calgary Health Region undergoing resection of a colloid cyst between 1991 and 2004. Comparison was made between patients treated with endoscopic resection versus microsurgical resection. Results: Twenty-five endoscopic and nine microsurgical procedures were performed. Complete resection was achieved in 24 of 25 procedures in the Endoscopic group, compared with all 9 procedures in the Microsurgical group. Patients in the Endoscopic group had a reduced operative time (mean 104 minutes versus 217 minutes) and reduced length of stay (3.8 days versus 8.4 days) compared to the Microsurgical group. One patient in the Endoscopic group had a complication (hemiparesis/pulmonary embolus). By contrast, 3 patients in the Microsurgical group had complications (seizure, ventriculitis/bone flap infection, and transient memory deficit). There was one recurrence in each group which both occurred at 5 years follow-up. The mean length of follow-up is 38 months in the Endoscopic group and 33 months in the Microsurgical group. Conclusion: Endoscopic resection of colloid cysts can be performed with significantly lower risk of complication than microsurgical resection and with equivalent surgical success. Operative time and length of hospital stay are both significantly reduced with endoscopic resection.

Colloid cysts of the third ventricle of brain comprise 1-2% of all intracranial tumonrs [1]. They-are increasingly being discovered incidentally, often in patients complaining of headache [2]. We came across two such cases in a large tertiary care service hospital in the past 20 years. Second case also had associated visual disturbances and seizures. Both met 'with fatal outcome. Autopsy revealed presence of colloid cyst in the third ventricle in both cases. It is proposed that to avoid fatal outcome in a patient reporting with frequent attacks of headache, the presence of colloid cyst in the third ventricle should be considered in differential diagnosis. In such cases,~T scan or MRI study of brain becomes an essential diagnostic tool.

Object. An optimal entry point and trajectory for endoscopic colloid cyst (ECC) resection helps to protect important neurovascular structures. There is a large discrepancy in the entry point and trajectory in the neuroendoscopic literature.Methods. Trajectory views from MRI or CT scans used for cranial image guidance in 39 patients who had undergone ECC resection between July 2004 and July 2010 were retrospectively evaluated. A target point of the colloid cyst was extended out to the scalp through a trajectory carefully observed in a 3D model to ensure that important anatomical structures were not violated. The relation of the entry point to the midline and coronal sutures was established. Entry point and trajectory were correlated with the ventricular size.Results. The optimal entry point was situated 42.3 ± 11.7 mm away from the sagittal suture, ranging from 19.1 to 66.9 mm (median 41.4 mm) and 46.9 ± 5.7 mm anterior to the coronal suture, ranging from 36.4 to 60.5 mm (median 45.9 mm). The distance from the entry point to the target on the colloid cyst varied from 56.5 to 78.0 mm, with a mean value of 67.9 ± 4.8 mm (median 68.5 mm). Approximately 90% of the optimal entry points are located 40-60 mm in front of the coronal suture, whereas their perpendicular distance from the midline ranges from 19.1 to 66.9 mm. The location of the "ideal" entry points changes laterally from the midline as the ventricles change in size.Conclusions. The results suggest that the optimal entry for ECC excision be located at 42.3 ± 11.7 mm perpendicular to the midline, and 46.9 ± 5.7 mm anterior to the coronal suture, but also that this point differs with the size of the ventricles. Intraoperative stereotactic navigation should be considered for all ECC procedures whenever it is available. The entry point should be estimated from the patient's own preoperative imaging studies if intraoperative neuronavigation is not available. An estimated entry point of 4 cm perpendicular to the midline and 4.5 cm anterior to the coronal suture is an acceptable alternative that can be used in patients with ventriculomegaly.
