Male, 48 years old, with grade 2 oligodendroglioma. The left superior frontal resection cavity is redemonstrated showing no significant change in size or confirmation. Nodular enhancement projecting into the cavity from the midline falx, and linear enhancement along the posterior inferior cavity margin, are unchanged and nonspecific. A rim of T2 hyperintensity around the cavity margins is seen which coalesces to a more bandlike area of hyperintensity along the roof of the left lateral ventricle. The extent of this signal abnormality shows very slight interval progression over the last two exams.Elsewhere in the brain, a few scattered small foci of nonspecific T2 hyperintensity are seen without significant change. No additional areas of pathologic parenchymal or extra-axial enhancement are seen. No significant generalized mass effect is detected. The ventricles are normal in size and morphology.
No definite concerning interval changes are seen. A very mild slow progression of T2 hyperintensity is seen over recent prior exams along the resection cavity margin and below the resection cavity which is nonspecific but may very well represent a treatment related effect. Continued follow-up is advised.
