37 years, Male, Reason: Eval grade II astrocytoma. Pt has NOT had RT. Please compare to most recent scan as well as back to postop scan. History: grade 2 astrocytoma.. Again seen are postsurgical changes of left frontal craniotomy for tumor resection. Compared to examinations from 9/10/2014 and 5/24/2013, there is gradually progressive increase in T2 hyperintensity surrounding the left superior frontal gyrus resection cavity extending to the left frontal horn. There is also a new nodular focus of enhancement measuring approximately 6 x 6 x 11 mm along the lateral aspect of the resection cavity, not present on prior study from 9/10/2014.No significant intracranial mass effect. Remainder of the brain parenchyma is unremarkable. No new sites of tumor. There is unchanged ex vacuo dilatation of the left frontal horn. Ventricles are otherwise normal in size. No evidence of acute ischemia or hemorrhage. Calvarium and extracranial soft tissues are also unremarkable.
Compared to prior examinations from 9/10/2014 and 5/24/2013 there is evidence of gradual increase in T2 hyperintensity surrounding the left superior frontal gyrus resection cavity and extending to the left frontal horn. There is also interval development of a new 6 x 6 x 11 mm enhancing nodule along the lateral aspect of the resection cavity. These findings are concerning for gradual tumor progression, especially in the absence of radiation therapy.
