Status post craniotomy for sphenoid/cavernous sinus meningioma in July 2012. There are changes of previous resection of the right frontal and paraclinoid meningioma resection. There is a surgical tract in the right frontal lobe at the depth of which there is punctate diffusion restriction, most likely reflecting blood products. Otherwise, there is no acute infarct. The lobulated T1/T2-hypointense signal along the inferior half of the craniotomy flap remains unchanged, representing bone cement. Cavernous sinuses enhance symmetrically. The ventricles and sulci are unchanged. There is mild ethmoid mucosal thickening.
Postoperative findings without evidence of tumor recurrence.
