Male 37 years old with history of anaplastic astrocytoma four weeks post RT/TMZ Evolution of post-surgical changes related to a recent frontal craniotomy for tumor resection with mildly increased T2/FLAIR hyperintensity along the posterior aspect of the superior frontal gyrus, which extends to the left frontal horn. Ex-vacuo dilatation of the left frontal horn appears unchanged. Increased extra-axial enhancement beneath the craniotomy is compatible with expected evolution of post-surgical changes. Previously described nodular enhancement along the anterolateral aspect of the resection cavity has decreased in prominence (series 1302 image 85). No new or enlarging suspicious pattern of enhancement identified.The basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. Evolution of postsurgical changes related to recent re-resection of recurrent left frontal lobe tumor. No clear evidence of tumor progression. Mild interval increase in T2/FLAIR hyperintensity along the left superior frontal gyrus extending to the left frontal horn may represent post-treatment change given recent irradiation.2. Previously described nodular enhancement along the anterolateral aspect of the resection cavity is less conspicuous. No new or enlarging suspicious pattern of enhancement identified.
