60-year-old male with a history of glial neural tumor status post resection, radiation therapy, biopsy. There are postoperative findings related to left frontal craniotomy for tumor resection. Although the postcontrast sequences are limited secondary to motion, the ovoid area of enhancement along the anterior margin of the right frontal horn is similar in appearance allowing for differences in technique, with persistent hemosiderin staining. There is also no significant interval change in the surrounding confluent areas of T2 hyperintensity in the bilateral frontal lobes, adjacent to the surgical cavity. There is a previous procedural tract in the right frontal lobe with resultant hemosiderin. There is also an associated small amount of hyperintense FLAIR signal in this same region indicating gliosis. There is also some curvilinear sulcal susceptibility abnormality located along the right lateral frontal sulci and along the paramedian frontoparietal sulci bilaterally indicating hemosiderin staining along the sulci, which is slightly decreased compared to previous exam. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. There is scattered paranasal sinus mucosal thickening. The left TMJ has a small amount of fluid in the joint, likely degenerative.
Unchanged post-treatment findings in the left greater than right frontal lobes without evidence of tumor progression.
