Background Meningiomas are the most common benign intracranial tumors, and commonly comprise high-vascularizing but slow-growing tumors. On the other hand, meningiomas arising from the ventricular system are of rare occurrence, and spontaneous hemorrhage is an infrequent event. Case presentation We describe here the rare clinical manifestations of a 28-year-old female with acute intracranial hemorrhage located in the trigone of the lateral ventricle who was initially thought to have suffered an acute cerebrovascular accident, but was subsequently confirmed to have a benign intraventricular meningioma. To clarify the clinical features of such a rare course of meningioma, we also present a short literature review of acute intracranial hemorrhage caused by intraventricular meningioma. Conclusions Ventricular meningioma presenting with hemorrhage such as acute stroke is a rare event, but recognition of such a pathogenesis is important. Although further accumulation of clinical data is needed, we suggest that early surgery should be undertaken in patients with lateral ventricular meningioma, even if it is not so large or asymptomatic.
The coronavirus disease 2019 (COVID-19) epidemic has had a major impact on stroke treatment. The acute ischemic stroke (AIS) treatment protocol at our hospital now requires a rapid antigen test on arrival to prevent the spread of COVID-19 infection, so the initiation of treatment may be delayed. We compared AIS treatment before (October 2018 to March 2020) and after the epidemic started (April 2020 to September 2021) to investigate the effect of COVID-19. The number of AIS emergency transports was 73 before and 102 after the epidemic. The time from door to image time was significantly extended ( p < 0.05). However, door-to-puncture time and puncture-to-recanalization time showed no significant changes. Possibly our revision of the protocol, such as omitting some imaging examinations, including magnetic resonance imaging, enabled more rapid interventions.
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.
