one important aspect not mentioned: the " long " 1 year "benign" history of the symptoms... not likely for malginant lymphomas, astros or metastasis to stay that calm

of course in addition to all other mentioned here "not brain infiltrating etc."

goldenwakosu I think it’s because meningiomas are able to calcify (aka sometimes they have psamomma bodies). I got this question wrong too but I totally did not completely register that the tumor was in the dura (interhemispheric fissure + central sulcus). Hope that helps! +2
