Clinical question: History of ovary and cancer with brain metastases. Status post resection and cavity SRS. Interval evaluation. Signs and symptoms: As above. Pre-and post-enhanced brain MRI: No diffusion weighted abnormalities.Significant interval improvement in postoperative changes of left parietal tumor resection.There is also decrease in edema surrounding the surgical cavity since prior exam. A collapsed surgical cavity containing blood product and minimal fluid measures at approximately 6.6 x 18-mm. It demonstrate thin linear loculated internal enhancement. The measurements of the enhancement are at 12 times 22.6-mm. The measurements of the enhancing lesion on sagittal post enhanced (series 1203) on image 60 are at 19 x 22 mm.There is no detectable new foci of parenchymal signal abnormality or abnormal enhancement or parenchymal/leptomeninges.New since prior exam is a small left frontal and parietal subdural collection measuring approximately 5.9 mm in the frontal and approximately 3 mm in parietal region.
1.Significant interval improvement of postoperative changes of tumor resection of left parietal lobe.2.Interval significant decreased size of the surgical cavity which demonstrate thin linear loculated enhancement as detailed/measured above.3.New since prior exam is a thin left frontal and parietal subdural collection measuring approximately 5.9 mm in frontal and 3mm in parietal.
