Metastatic prostate cancer. There is redemonstration of findings related to right posterior parietal craniotomy with a small amount of fluid in presumably blood products at the operative site. The cystic mass overlying the right parietal lobe has been grossly resected. A punctate enhancing focus in the right lateral margin of the section cavity may represent granulation tissue or a focally dilated vein. There is otherwise minimal residual edema in the brain parenchyma surrounding to the surgical bed. There is unchanged diffuse dural thickening and enhancement particularly along the bilateral cerebral convexities, measuring up to 10 mm in maximal thickness on the right side. There has been interval decease in the edema adjacent to the left inferior frontal lobe lesion. There is leftward midline shift of approximately 5 mm. The basal cisterns remain patent. There is no evidence of new mass or acute infarct. The major cerebral flow voids are intact. There is persistent fluid in the mastoid air cells bilaterally. There is a small retention cyst in the right maxillary sinus. The orbits and scalp soft tissues are grossly unremarkable.
1.Postoperative findings related to right posterior parietal craniotomy and resection of an right parietal dural metastasis with markedly decreased surrounding right parietal lobe edema.2. No significant change in size of the extensive remaining bilateral dural based metastatic disease, although left inferior frontal lobe edema has subsided.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
