Childhood meningiomas are rare and display important differences from adult forms. We report the first case of an intraventricular metaplastic meningioma arising in a child. A 7-year-old female underwent resection of an enhancing tumor arising within the left lateral ventricle. It was composed of monomorphic cells embedded within an abundant myxoid stroma. The cells demonstrated epithelial membrane antigen and vimentin immunoreactivity. Ultrastructural analysis demonstrated intermediate filaments, complex intercellular interdigitations and desmosomes, and a diagnosis of myxoid (metaplastic) meningioma was rendered. This case reflects the higher incidence of intraventricular meningiomas in childhood and greater incidence of intraventricular meningiomas in the left lateral ventricle. Recognition of the grade I myxoid meningioma in this case is paramount since chordoid meningiomas, which share similar histologic features, are of a higher grade and worse prognosis.
Many first‐year medical students find imaging studies to be an abstract and difficult topic to learn. Understanding and interpreting imaging studies such as Magnetic Resonance (MR), Computed Tomography (CT) and ultrasound requires proficient knowledge of cross‐sectional anatomy of the human body. Our study aims to evaluate the use of an online module, which utilizes cadaveric gross cross‐sectional anatomical photographs of the thigh and correlates such viewpoints with the respective MR, CT and ultrasound images. Medical students at Oakland University William Beaumont School of Medicine were given access to the online module. We designed this module to consist of a pre‐module quiz, the module itself, and a post‐module quiz. The module contains cadaveric cross‐sectional photos of the thigh at three different levels as well as corresponding imaging studies of the thigh. Each eight‐question pre‐module and post‐module quiz contains two MR, two CT, two ultrasound, and two cross‐sectional anatomy questions. Comparison of students’ pre‐ and post‐ module scores as well as student scores on exam questions relevant to the module content will be used to evaluate whether the module has successfully aided students in learning the various imaging modalities. A survey will be sent to students to seek their feedback on the module in order to improve it for future medical students. This research uses a novel approach by correlating anatomical photographs with the imaging modalities; other studies exclude the ultrasound or use of clay models rather than imaging. Medical students have received the online module, and we are awaiting the results of this study, which could contribute to the future of medical education and the ease of learning MR, CT, and ultrasound via cross‐sectional anatomy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
