Male, 62 years old, with brain metastasis status post resection. MRI from postoperative serous treatment planning. Redemonstrated is evidence of right anterior temporal tumor resection. The surgical cavity is similar in size to that seen on the prior examination. Thin enhancement is evident around a majority of the resection cavity. Enhancement measuring up to 10 mm in thickness is, however, seen along the posterior margin of the cavity, along with a subcentimeter focus of enhancement medially along the cavernous sinus margin. No enhancement was evident in these areas on the immediate postoperative examination, but rather, there was restricted diffusion correlating to both sites.Generalized right cerebral mass effect has significantly improved from the prior examination. No additional enhancing intracranial lesions are seen. Ventricular caliber is within normal limits.
1.Demonstration of findings related to resection of tumor from the right anterior temporal lobe.2.Enhancement along the posterior margin of the resection cavity measuring up to 10 mm in thickness is new from the prior examination. However, given that it correlates with cytotoxic edema on the prior examination, it is favored to represent postsurgical change.
