Female, 59 years old, status post craniotomy. A small left convexity craniotomy is seen through which the previously demonstrated enhancing mass in the left posterior frontal lobe has been resected. The surgical cavity contains fluid and a small heme level. Thin diffusion restriction around the cavity margins is compatible with procedural cytotoxic edema. No evidence of residual tumor is seen. Vasogenic edema surrounding the operative bed is similar to that seen preoperatively.Elsewhere, no additional pathologic enhancement or suspicious signal abnormality is seen. Scattered foci of T2 hyperintensity within the white matter are unchanged and nonspecific. Ventricular size and morphology are within normal limits. Partial opacification the right mastoid air cells is seen.
Expected findings are seen status post resection of a tumor from the high left posterior frontal lobe. No residual tumor is identified.
