Meningiomas are the most diagnosed primary central nervous system tumor. Currently, 15 different subtypes of meningioma exist with various characteristics. One extremely rare subtype is myxoid meningioma, which is a World Health Organization grade 1 benign meningioma. These specific meningiomas have only been reported 12 times in the literature. In this representative case, we present a 46-year-old female patient with a left frontal myxoid meningioma, describe the findings on imaging, and provide the histopathological features that are needed for diagnosis. Furthermore, this report discusses the other existing myxoid meningioma case reports found throughout the literature.
