58 years, Male, status post left parietal tumor resection. Post surgical findings consistent with left parieto-occipital craniotomy for left parietal lobe mass resection are redemonstrated. Minimal cytotoxic edema surrounds the resection cavity, which may transiently enhance on subsequent follow-up imaging. Given the relative lack of significant solid enhancing tumor on the preoperative study, evaluation for residual tumor is slightly limited. There is minimal linear enhancement along the periphery of the resection cavity, at least most of which appears to be related to vasculature. Blood products fill the resection cavity. There is redemonstration of left parietal lobe and left posterior temporal lobe increased T2 signal, which may again represent vasogenic edema and/or underlying infiltrating tumor, with effacement of the posterior horn of the left lateral ventricle and blunting of the parietal convexity sulci. Minimal rightward midline shift is not significantly changed. A small extra-axial fluid collection is again noted adjacent to the craniotomy site consistent with postoperative change.Minimal scattered foci of nonspecific T2/FLAIR hyperintensity are present in the subcortical white matter bilaterally, as on previous examination. There is no evidence of hydrocephalus. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear.
Gross total resection of the left parietal mass. No definite evidence of enhancing residual tumor.
