47 years, Male, evaluate for tumor resection, word finding difficulty. There are postsurgical changes of left-sided craniotomy for resection of left temporal mass. There is a rind of restricted diffusion surrounding the resection cavity compatible with cytotoxic edema. No large infarct is evident. There are blood products within the resection cavity. There appears to be near total resection of the enhancing tumor with small residual enhancement suspected along the superior aspect of the resection cavity abutting the left temporal horn.Extensive surrounding T2/FLAIR hyperintensity in the left temporal lobe extending medially into the left thalamus and basal ganglia region as well as superiorly into the left parietal white matter is again seen. Mass effect including effacement of the left lateral ventricle is slightly improved. Uncal herniation with deformity of the midbrain and rightward displacement of the brainstem is slightly improved. Rightward midline shift measured at the foramen of Monro measures approximately 6 mm compared to 8 mm on the preoperative study. No hydrocephalus. Major flow-voids are maintained. There is diffuse opacification of the left mastoid air cell. Remainder of the brain parenchyma demonstrates few scattered nonspecific T2/FLAIR hyperintense foci but otherwise unremarkable.
Expected postsurgical changes of left temporal tumor resection. There is near total resection of the enhancing tumor with minimal residual enhancement suspected along the superior aspect of the resection cavity along the left temporal horn.
