Post tumor resection follow-up Previously recognized left frontal lobe opercula intra-axial mass has been resected. Local postoperative changes are seen including resection area high signal intensities on FLAIR imaging and extra axial fluid collections.On gradient echo images, there are nodular and linear signal voids indicate local resection site blood products.High signal intensities on the resection site on FLAIR and T2 images which suggest post resection changes most likely. However, possibilities of residual mass can be completely excluded.Minimal extra cranial fluid collections are seen overlying craniotomy site, again not unusual postoperative changes. The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Post left frontal opercular tumor resection status. No unusual finding.2. High signal intensities around tumor resection site may indicate postoperative changes but cannot completely exclude possibility of residual tumor.
