History of breast cancer with newly diagnosed right parietal brain lesion, status post recent right tumor resection. There are recent postoperative findings related to right precuneus tumor resection, with blood products in the treatment bed region. There is enhancement along the margins of the resection cavity, particularly the superior and inferior margins, measuring up to 10 mm in thickness. There is also confluent T2 hyperintensity surrounding the resection cavity. There is an extradural fluid collection deep to the craniotomy flap that measures up to 5 mm in thickness. There is also overlying diffuse scalp swelling and fluid. There is no evidence of acute territorial infarct. There are mild scattered nonspecific foci of T2 hyperintensity. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits are grossly unremarkable.
Recent postoperative findings related to right parietal lobe tumor resection, with what likely represent residual tumor along portions of the surgical margins and persistent surrounding vasogenic edema.
