follow up of right tentorial lesion, likely to be meningioma. There is again 8.9mm x 11.4mm x 10mm sized right tentorial based extra axial mass likely representing meningioma.The size, signal characteristics do not show any significant interval change since prior exam.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
No change of right tentorial based extra axial mass in terms of size (8.9mm x 11.4mm x 10mm), configuration and MR signal characteristics since prior exam.No evidence of acute ischemic or hemorrhagic lesion.
