Secondary malignant neoplasm of brain and spinal cord [198.3], Reason for Study: ^Reason: eval post surgical resection History: brain lesion There is evidence of right fronto-parietal craniotomy with biopsy of the right frontal pre central gyrus lesion.In fact, the size of the lesion appears to be slightly smaller and shows central unenhancing portion with peripheral enhancement.There are multiple enhancing lesions which are similar to prior scan performed on Sep 14 2015. However, there are new enhancing and/or more conspicuous lesions on Gad enhanced images including left middle frontal gyrus (series 501, image 145), left inferior frontal gyrus (series 501, image 126), and right cingulate gyrus (series 501, image 113).Other scattered lesions including right posterior temporal lobe, right cerebellar hemisphere and left cerebellar small hemorrhagic lesion appear to be stable.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. The mild mucosal thickening of bilateral maxillary sinus and opacification of the mastoid air cell (right greater than left) do not show any significant interval change.
1. Post surgical resection status of the right pre central gyrus lesion.2. There are lesions which are either new or more conspicuous on today's scan than prior exam as described above.3. Most of other scattered enhancing lesions including right posterior temporal and right cerebellar hemisphere appear to be stable.
