Clinical question: Status post tumor resection. Signs and symptoms: Status post craniotomy. Pre-and post-enhanced brain MRI:Examination demonstrates extensive postoperative changes of a right frontal/parietal craniotomy for removal of tumor. A small surgical cavity measuring approximately 9 x 14 mm in transaxial dimension with extensive surrounding residual vasogenic edema is present. Post-enhanced images demonstrate no convincing evidence of residual enhancement within or surrounding the surgical cavity to suggest residual tumor. Further follow-up however is needed. Constellation of findings results in regional mass-effect and without evidence of mass effect on the lateral ventricle or midline shift.The ventricular system remain within normal size similar to prior exam.Previously noted small enhancing metastatic lesions in the left hemisphere are again identified and without change. A tiny left frontal lobe developmental venous anomaly is again identified.
1.Post operative changes of right hemispheric tumor resection without detectable residual tumor on this initial study.2.Demonstration of tiny additional metastatic lesions and a small left frontal developmental venous anomaly.3.Stable normal size of ventricular system and with maintained midline.4.
