Paraventricular meningioma revealed by mental disorder

Abstract

Background:Ventricular meningioma constitutes 2% of intracranial meningioma, representing a challenging disease for neurosurgeons. 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.Case Descriptions:We report the case of a large lateral ventricle meningioma revealed by cognitive dysfunction and moderate intellectual disability. The patient underwent subtotal resection of the tumor which had partial improvement in cognitive disorders. It is important to precisely assess neuropsychological function in patients with large brain tumors, and judicious preoperative plan, adequate knowledge of anatomy, and use of correct microsurgical techniques are fundamental in achieving complete resection of paraventricular meningioma with low morbidity.Conclusion:Pre and postoperative precise neuropsychological examinations may identify the potential cognitive impairment and beneficial effects of surgery in patients with large lateral ventricle meningiomas.

Functional Ultrasound (fUS) During Awake Brain Surgery: The Clinical Potential of Intra-Operative Functional and Vascular Brain Mapping

“…For those tumors with vessels of origin, for example, fUS-guided targeted tumor therapies would be an interesting approach. What is more, using our fUS-data in real-time during tumor removal could possibly allow for vascularity-guided tumor resection, in parallel to the treatment of meningiomas with so called 'pedicles, ' where early access to the vascular origin facilitates safe and effective tumor resection (Dowd et al, 2008;Watts et al, 2014;Hilmani et al, 2016). It would be worthwhile to focus future efforts on imaging heterogeneous groups of brain tumors and comparing and contrasting vascular structure across histopathological gradings, not only in awake but also in anesthetized patients.…”

Parasagittal meningiomas – literature review and a case report

“…Current tendency 41 nowadays is resection of the meningioma outside the walls of the sinus with coagulation of the tumor remnant, followed if needed by an "en bloc" removal of the residual tumor when complete sinus occlusion occurs (6,7,10). …”
