“…20,51 A review of 47 lateral ventricle tumors examined by radiologists at the Armed Forces Institute of Pathology was performed using CT and/or MR imaging studies, and the authors found that tumors seemed to occur in age-related groupings. 20 Tumors found in the lateral ventricle of children younger than 5 years of age were often choroid plexus tumors, whereas in older children they tended to be glioma. Choroid plexus tumors are often quite vascular and demonstrate a tumor blush on MR angiography and angiography.…”

Object Tumors of the lateral ventricle can be removed via two major approaches: the transcallosal or the transcortical route. The purpose of this study is to discuss the techniques and outcomes in transcortical surgery of tumors located in the lateral ventricle. Methods An experience with 29 consecutive lateral ventricular tumors resected via the transcortical route, over a 5-year period, is presented. The risks, complications, and outcomes of this surgical series, as well as those reported in the literature, are discussed. Surgical approaches to all five regions of the lateral ventricle are described. Neuropsychological, functional, and neurological outcomes are evaluated. Conclusions The transcortical technique makes it possible to resect lesions in each of the five regions of the lateral ventricle. It provides superior microsurgical working space and flexibility for maneuvering within the lateral ventricle. The key to a successful transcortical approach is an understanding of the functional anatomy of eloquent cortex to be broached, the location of the lesion, and its vascular supply. A clear understanding of the advantages and limitations of the transcortical approach makes performing this procedure for resection of large lesions in the ventricle both safe and effective. The majority of the patients in this series (86%) had a good outcome, returning to baseline functional status and suffering minimal morbidity. In the microsurgical era, transcortical surgery–related postoperative morbidity and outcome are dependent more on tumor histological type and site of origin than on approach.

“…Ependymoma, when supratentorial, can be intraventricular as well as intraparenchymal. 20 In this series, I report on ependymomas that originate in the ventricle. In adults older than 30 years of age, tumors in the atrium and trigone are most commonly meningiomas.…”

“…2,3 DiŠerential diagnoses of other lateral ventricular mass lesions include astrocytoma, meningioma, choroid plexus tumor, central neurocytoma, subependymal heterotopia, subependymal nodule, ependymoma, lymphoma, and metastasis. [4][5][6][7] Because subependymomas, subependymal heterotopias, and subependymal nodules are small lesions in the lateral ventricle, it is important to distinguish them from RSLVNs. Subependymal heterotopia and subependymal nodule can be diagnosed based on clinical history and radiologicalˆndings.…”

Purpose: We evaluated the prevalence and imaging characteristics of ring-shaped lateral ventricular nodules (RSLVNs) detected by postcontrast brain magnetic resonance (MR) imaging.Materials and Methods: We retrospectively reviewed cranial MR images of 1,241 patients who underwent contrast-enhanced brain imaging between January 1, 2008 and March 31, 2011, excluded images of inadequate quality of 130 patients, and ultimately analyzed images of 1,111 patients (544 male, 567 female). We assessed location, shape, and signal intensity of RSLVNs on T 1 -weighted (T 1 WIs), T 2 -weighted (T 2 WIs), ‰uid-attenuated inversion recovery (FLAIR), and diŠusion-weighted (DWIs) images and characteristics of contrast enhancement.Results: In 5 patients, we found 6 RSLVNs (0.45z), four in the frontal horn and two in the roof of the body. Three RSLVNs were round, two were oval, and one was lobular on axial images. All 6 RSLVNs were isointense with adjacent brain parenchyma on T 1 WI, T 2 WI, and DWI but slightly hyperintense on FLAIR images; none showed enhancement on postcontrast MR imaging. Five nodules serially examined (range, 8 to 24 months) showed no interval changes.Conclusions: Our MR imagingˆndings of a 0.45z prevalence of RSLVNs shows they are not so rare as previously reported. Except for conˆguration, all nodules had similar intensity, and none showed contrast enhancement. Absence of changes during the follow-up period seemed to indicate that the nodules have no clinical signiˆcance. However, their clear diŠerentiation avoids unnecessary surgery.

“…Intraventricular meningiomas account for 9.8-14% of all intraventricular tumors and for 20% of lateral ventricle tumors [1,2]. Meningiomas of the lateral ventricle constitute 0.5-4.5% of all intracranial meningiomas [3,4].…”
