History of prostate cancer. Right temporal mass. Assess extent of resection. There are findings related to the recent right temporal craniotomy for resection of a left temporal mass. There is residual abnormal enhancement along the posterior and medial surgical margins, measuring up to 8 mm in thickness. The surgical cavity contains filled with heterogeneous fluid and gas. The associated extensive surrounding vasogenic edema with associated partial ventricular effacement and 6 mm midline shift are unchanged. There is mild diffusion restriction along the surgical margin. Otherwise, there is no acute territorial infarct. There is an area of susceptibility effect within the right temporal lobe posterior to the surgical cavity that measures up to approximately 25 mm. The 10 mm enhancing focus in the anterior right temporal lobe is unchanged. There are bilateral lens implants.
1. Recent right temporal craniotomy for resection of a left temporal mass, with residual tumor along the posterior and medial surgical margins, measuring up to 8 mm in thickness, and extensive surrounding tumor infiltration and/or edema. 2. A smaller lesion in the anterior right temporal lobe likely represents additional tumor.3. Intraparenchymal hemorrhage within the right temporal lobe posterior to the surgical cavity that measures up to approximately 25 mm appears unchanged, accounting for differences in technique.
