 As seen on the recent MRI neck, there is enhancing mass in the left posterior cerebellum, measuring 1.4 x 1.6 cm in greatest axial dimensions, with prominent surrounding T2/FLAIR hyperintensity and effacement of the cerebellar sulci, due to localized mass effect from the vasogenic edema. No other enhancing lesion is identified. There is a nonspecific focus of T2/FLAIR hyperintensity in the left parietal centrum semiovale without enhancement.The ventricles and sulci are within normal limits. The cisterns remain patent. There is no midline shift. There is no diffusion abnormality. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. Marrow signal within the clivus and inferior occipital bone appears fatty, relative to other areas which may be related to post radiation changes in the field of prior treatment.
1. Redemonstration of left cerebellar metastasis with prominent surrounding vasogenic edema and minimal localized mass effect. No other definite intracranial metastatic disease identified.2. Single punctate focus of nonenhancing T2/FLAIR hyperintensity in the left parietal centrum semiovale which is nonspecific.
