          Abstract

          Although cognitive impairment is one of the major symptoms of ventricular tumors, few studies have reported the details of cognitive impairment before and after their surgical removal. The expected effects on cognitive function should also be considered when choosing a surgical approach. We report the case of a large lateral ventricle meningioma in which cognitive impairment was detected on detailed neuropsychological examinations. The tumor was totally removed through the right superior temporal gyrus. Postoperative neuropsychological assessment revealed the reversal of cognitive impairment. As cognitive impairment is complex and easily overlooked, it is important to precisely assess neuropsychological function in patients with large brain tumors.

          Morbidity of transcallosal and transcortical approaches to lesions in and around the lateral and third ventricles: a single-institution experience.

          Karolin F Meyer, Daniel B. Milligan (2010)
          Resection of an intraventricular mass can result in life-altering complications. Many advocate transcallosal rather than transcortical approaches to these lesions, citing differential postoperative seizure risk. To test the hypothesis that the complication rates and patient outcomes are no different between these ventricular approaches. The medical records of 127 patients (93 adults and 34 children) operated on for intraventricular lesions between 1996 and 2007 were retrospectively analyzed. Risk factors for specific postoperative complications and outcome were assessed by multivariate analysis. The transcallosal (59%) or transcortical (41%) approach was used. Gross or nearly total resection was achieved in 87% of cases. The permanent neurological complication rate determined by a staff neurologist was 23.6%. Seizure attributable to surgery occurred after 8% of transcortical and 25% of transcallosal operations (P=.01). After controlling for a variety of factors, the transcallosal approach carried a 4.4-fold increased risk of seizure (95% confidence interval, 1.3-18.9). The operative approach was not a risk factor for any other postoperative complication. One year after surgery, 72% of patients had excellent functional outcome (Karnofsky Performance Score≥70 and Glasgow Outcome Score=5). High tumor grade and impaired preoperative Karnofsky Performance Score predicted poor outcome. More than 90% of patients operated on for symptomatic colloid cysts (n=34) had an excellent outcome. Although the 2 traditional approaches to the ventricular system had similar major complication rates, the transcallosal approach was associated with significantly increased seizure risk. Accordingly, the chosen operative corridor should optimize tumor access and the protection of vulnerable neurovascular structures.

            MR tractography predicts visual field defects following temporal lobe resection.

            J. Parker, Fred G Barker, Roger Alexander … (2005)
            A superior homonymous quadrantanopia is a well recognized complication of anterior temporal lobe resection and occurs because of disruption of the Meyer loop, the anterior part of the optic radiation. The authors used diffusion tensor imaging tractography to visualize the optic radiation before and after surgery, demonstrating the disruption of Meyer loop in a patient who developed a quadrantanopia. Preoperative imaging of the optic radiation will be useful in predicting visual field defects following temporal lobe resection.

              Meningiomas of the lateral ventricles. Clinical, neuroradiologic, and surgical considerations in 19 cases.

              R. Delfini, F. GAGLIARDI, B Guidetti … (1985)
              The clinical and neuroradiologic findings and surgical results in a series of 19 patients with lateral ventricle meningioma, operated on during a 33-year period, are described. This experience is compared with that of previous workers and the following conclusions are drawn: these tumors have no characteristic symptoms; preoperative diagnosis requires both computed tomography scans and carotid and vertebral angiography; the safest surgical approach is through a sagittal or oblique parietooccipital cortical incision to avoid damage to motor, visual, and speech areas of the cortex.
