Comparison has been made to previous imaging. All the large previously demonstrated lesions have a least somewhat reduced in size. The largest lesion, adjacent to the lateral ventricle on the left, beneath the motor strip remains by far the largest, and has only marginally reduced in size, but has reduced significantly in contrast enhancement.
Immediately posterior to this lesion, too small focal regions of high T2 signal measuring 4mm and 7mm respectively have increased when compared to previous scan, although both were previously visible also. These demonstrate restricted diffusion, and the more posterior of the two, contrast enhancement which has also increased.
MRS demonstrated increased Choline, decreased NAA, with increased lipids and lactate.
