Surgical Experience with Lateral Ventricular Choroid Plexus Papilloma in Children

Abstract Background: Surgical experience with lateral ventricular choroid plexus papilloma in children introduction choroid plexus papilloma is the most common lateral ventricular tumor in the children with frequent location in the atrium surgical access to the lateral ventricle remains one of the challenging procedures in the neurosurgery because of the deep location and relation to vital structures especially eloquent area of the brain. In this study, the transcortical microscopic surgery was used to reach the tumor and identify it’s vascular and structural relation with minimal cortical incision. Endoscopic assisted microscopic surgery was done in the last two cases. Aim of Study: To understand and learn more about one of the most challenging brain tumors (lateral ventricular choroid plexus papilloma) in children and to overcome the difficulties and complications in treating such as these kind of brain tumors to improve the quality of life in these children. Patients and Methods: The seven cases of trigonal location were operated using posterior parietal lobule incision in the dominant side or small tumors in nondominant side and parietotemporal junction incision in large tumors stretching the cortex in nondominant side. The case located in the frontal horn of lateral ventricle was operated by transcortical frontal incision Endoscopic access to the ventricle and navigation of the tumor were done through small incision which was followed by microscopic removal were done in the last two cases. Results: Total removal was done in six cases and in the remaining two another surgical setting were needed to achieve total removal two cases had postoperative visual deficit and one case transient motor deficit and one case had transient sensory aphasia, endoscopic assisted approach provide short and safe way to the atrium with excellent identification of tumor extension, vascular pedicle and relation and also can help and check total removal. Conclusion: Choroid plexus papilloma is uncommon tumor that need special surgical plane and knowledge. Endo-scopic assisted access to the lateral ventricle enhances safe and total microscopic removal of this vascular tumor through small cortical.
