“…The recurrence rate after microsurgical procedures was one (1.1%) of 93, with follow up from 1 month to 25 years (mean 3 years 8 months). 5) In contrast, the recurrence rate of aspiration procedures was seven (43.8%) of 16 after long-term follow up . 17) This high recurrence rate is due to the residual cyst wall which secretes the colloid material.…”

A 60-year-old man presented with a left frontal mass lesion incidentally detected at a health check without apparent symptoms. Computed tomography revealed the lesion as homogeneous high density and magnetic resonance (MR) imaging showed the lesion as hyperintense on T 1 -weighted images, isointense on T 2 -weighted images, and hypointense on diffusion-weighted images. T 1 -weighted MR images with gadolinium showed no enhancement of the mass lesion. Cerebral angiography revealed an avascular area around the left frontal lesion. Total removal of the lesion was achieved through a craniotomy without complications. Histological, immunohistochemical, and electron microscopy examinations established the definite diagnosis of colloid cyst.

“…Several studies have demonstrated the safety of the technique and its insignificant cognitive repercussions. [2][3][4]7,8,15,21,22,28,30 Gaffan and Gaffan performed an extensive review of this topic and concluded that bilateral sectioning of the fornix causes memory deficits; however, there is no consistent evidence that unilateral sectioning of the fornix can affect memory.…”

“…30,38 There is evidence that a unilateral lesion of the fornix column has little or no impact on memory. 2,4,8,15,22,25,28,30,43 Various regions and structures participate in the memory circuit, and the fornix is just one of these structures. Changes to other parts of this circuit would therefore be necessary to establish a permanent memory deficit.…”

OBJECTIVE Access to the third ventricle is a veritable challenge to neurosurgeons. In this context, anatomical and morphometric studies are useful for establishing the limitations and advantages of a particular surgical approach. The transchoroidal approach is versatile and provides adequate exposure of the middle and posterior regions of the third ventricle. However, the fornix column limits the exposure of the anterior region of the third ventricle. There is evidence that the unilateral section of the fornix column has little effect on cognitive function. This study compared the anatomical exposure afforded by the transforniceal-transchoroidal approach with that of the transchoroidal approach. In addition, a morphometric evaluation of structures that are relevant to and common in the 2 approaches was performed. METHODS The anatomical exposure provided by the transcallosal-transchoroidal and transcallosal-transfornicealtranschoroidal approaches was compared in 8 fresh cadavers, using a neuronavigation system. The working area, microsurgical exposure area, and angular exposure on the longitudinal and transversal planes of 2 anatomical targets (tuber cinereum and cerebral aqueduct) were compared. Additionally, the thickness of the right frontal lobe parenchyma, thickness of the corpus callosum trunk, and longitudinal diameter of the interventricular foramen were measured. The values obtained were submitted to statistical analysis using the Wilcoxon test. RESULTS In the quantitative evaluation, compared with the transchoroidal approach, the transforniceal-transchoroidal approach provided a greater mean working area (transforniceal-transchoroidal 150 ± 11 mm 2 ; transchoroidal 121 ± 8 mm 2 ; p < 0.05), larger mean microsurgical exposure area (transforniceal-transchoroidal 101 ± 9 mm 2 ; transchoroidal 80 ± 5 mm 2 ; p < 0.05), larger mean angular exposure area on the longitudinal plane for the tuber cinereum (transfornicealtranschoroidal 71° ± 7°; transchoroidal 64° ± 6°; p < 0.05), and larger mean angular exposure area on the longitudinal plane for the cerebral aqueduct (transforniceal-transchoroidal 62° ± 6°; transchoroidal 55° ± 5°; p < 0.05). No differences were observed in angular exposure along the transverse axis for either anatomical target (tuber cinereum and cerebral aqueduct; p > 0.05). The mean thickness of the right frontal lobe parenchyma was 35 ± 3 mm, the mean thickness of the corpus callosum trunk was 10 ± 1 mm, and the mean longitudinal diameter of the interventricular foramen was 4.6 ± 0.4 mm. In the qualitative assessment, it was noted that the transforniceal-transchoroidal approach led to greater exposure of the third ventricle anterior region structures. There was no difference between approaches in the exposure of the structures of the middle and posterior region. CONCLUSIONS The transforniceal-transchoroidal approach provides greater surgical exposure of the third ventricle anterior region than that offered by the transchoroidal approach. In the population studied, morphometric analysis estab...

“…However, microsurgical resection is associated with significant morbidity and prolonged post-operative hospital stays. 2,[20][21][22][23][24][25][26][27][28] More recently, some authors have reported less invasive microsurgical techniques with endoscopic assistance, 22 neuronavigation 29 and approaches through cylindrical retractors using stereotactic frames. 30,31 Although potentially less invasive, stereotactic aspiration is associated with recurrence rates of 30-80% [32][33][34] with recurrences occurring as early as two months in half of these.…”

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.
