Falx cerebri tuberculoma mimicking en plaque meningioma – case report

Abstract

Abstract Background: The involvement of falx cerebri in tuberculosis is extremely rare, with only three cases reported so far in the literature. The diagnosis is most often difficult to establish, given the location of the lesion, making surgical intervention necessary for a definite histopathologic diagnosis. Methods: We present the case of a 49-year old female patient who was admitted for a right jacksonian seizure, followed by a right crural monoparesis, without a history of tuberculosis. The lesion mimicked a falx cerebri en plaque meningioma in the imaging tests. Results: A complete surgical excision was performed through a left fronto-parietal parasagittal approach. The histopathological examination revealed a case of cerebral tuberculosis. The surgical treatment was complemented postoperatively with antituberculous therapy. Conclusion: In this article, we emphasize the rarity of the lesion at this level and also presenting similar cases from the literature. Moreover, we also discuss epidemiological, clinical, imaging, therapeutic as well as pathological aspects of en-plaque dural tuberculoma.
