15*20*25 mm intradural extramedullary solid mass at the craniocervical junction, posterior to clivus and C1 causing right posterolateral displacement of cervicomedullary junction. The mass shows iso to slightly hyperintense on T2W and isointense on T1W images. No evidence of local invasion on adjacent bone structures.
High signal foci in T2 and FLAIR sequences in the subcortical and periventricular white matter of both cerebral hemispheres depicts microvascular ischemic events.
Regarding the imaging findings (dural based mass isointense to grey matter on both T1 and T2 weighted sequences), craniocervical junction meningioma is the final diagnosis.
