This is meningioma because its in the interhemispheric fissure its not infiltrating the brain. All the other ones are within the brain tissue

meningiomas count as enhancing lesions? (this comment needs to be more than 50 characters apparently.)

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! +  
pipter  the only reason I got this right was because they described the tumour as being near the falx cerebri. +1  
fcambridge  Other hints include being described as round and seen in a female. Both indicative of Meningioma +2  
niboonsh  also meningiomas typically present with seizures or focal neurological signs +

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."
