postop follow up after large bifrontal meningioma There is evidence of bifrontal craniotomy with debulking of tumor.The area of Gad enhancement are now see on bilateral anterior skull base and posterior aspect of the tumor which is just in front of left side basal ganglia. Tumor mass involving right anterior and posterior ethmoidal sinuses remains unchanged.Approximately 80-90% of tumor mass have been removed.Subtle peritumoral high signal intensities on FLAIR indicating peritumoral edema are seen but the degree of mass effects to surrounding brain parenchyme and bilateral ventricles frontal horns appear to be stable (not worse). The gray-white matter differentiation is normal. There is intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. The mastoid air cells are clear.
Postoperative status of bifrontal meningioma, about 90% of tumor mass has been removed.Postoperatively no unusual finding.
