 An extra-axial homogenously enhancing mass lesion located in the left cerebellum along the tentorium has minimally increased in size, currently measuring 1.8cm (AP) x 1.8 cm (ML) x 2.0cm (CC), previously 1.6 x 1.7 x 2.0 cm with MRI 7/30/2015, respectively. There is no significant adjacent parenchymal edema. This lesion is adjacent to the left transverse sinus which is focally narrowed but patent proximally and distally, similar to the prior exam. There is an additional extra-axial enhancing lesion in the left frontal high convexity which is calcified on prior CTs measuring 7 mm in thickness and is also unchanged in size. No new enhancing lesions are present. There is no evidence of intracranial hemorrhage.There is a new T2/FLAIR hyperintense focus at the right temporoparietal occipital junction, which is nonspecific and may relate to ischemia or other injury. Otherwise scattered punctate foci of T2 and FLAIR hyperintensity within the white matter are nonspecific and may reflect minimal small vessel ischemic changes similar to prior. Ventricles are normal in size. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1.Minimal gradual increase in size of a left posterior fossa meningioma compared to prior studies from 7/30/2015 and 8/7/2014.2.Stable appearance of a subcentimeter enhancing extra-axial lesion along the left high convexity, consistent with an additional meningioma.3.Again seen are minimal scattered foci of T2/FLAIR hyperintensity which are nonspecific but compatible with mild chronic small vessel ischemic changes. There is however a new focus at the right temporo-occipital junction, which is nonspecific and may relate to interval ischemia, inflammation, or other injury. No evidence of acute infarct.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
