 There is redemonstration of a resection cavity involving the right anterior temporal lobe, a portion of the right insula, the frontal operculum, and a portion of the right inferior frontal lobe. The size and morphology of the resection cavity are unchanged. The degree of the T2 signal abnormality surrounding the resection cavity and extending into the right frontal white matter has not significantly changed. There is enhancement along the ependyma of the right frontal horn, which appears significantly more prominent than on the previous studies of 8/28/2015 and 7/10/2015. There is also a new focus of nodular enhancement along the ependyma of the left frontal horn. Enhancement in the midline along the septum pellucidum remains the same. Enhancement along the ependyma of the lateral aspect of the body of the right lateral ventricle is unchanged.There is enhancement along the medial aspect of the resection cavity, which is contiguous with the ependymal enhancement, which is not significantly changed. There is no evidence of restricted diffusion. There is susceptibility effect along the resection cavity, due to old blood products.There is fluid in the right mastoid and in the left maxillary sinus, unchanged.
1. Redemonstration of findings related to tumor resection and treatment. 2. Progressive ependymal enhancement is seen along the right frontal horn, with a new area of ependymal enhancement along the left frontal horn. 3. Stable appearance of the resection cavity.
