Male, 37 years old, with history of grade 2 oligodendroglioma status post radiation therapy, now on PCV. Findings are redemonstrated compatible with prior left frontal biopsy. A region of T2 hyperintensity involving predominantly the left frontal lobe white matter, but with some evidence of cortical thickening as well, is again seen showing no significant interval change in size or morphology. As on the prior examination, the anterior central portion of this lesion demonstrates bubbly FLAIR suppressing signal characteristics which may reflect cystic change. On postcontrast images, there is no convincing pathologic enhancement apart from some subtle vascularity which enters the lesion.No significant mass effect is detected. No evidence of any new parenchymal signal abnormality or pathologic enhancement is seen. The ventricular system is stable and within normal limits for size.Again seen is thickening and enhancement of the right orbital roof which on prior CT demonstrates a morphology most suggestive of fibrous dysplasia.
Stable lesion in the left frontal lobe with no findings to suggest progressive disease.
