NF1 with history of MPNST. Question of change in size of the sacral root lesion. An enhancing lesion at right S3 nerve root measures approximately 16 x 16 mm and is not significantly changed in size since the prior study. Numerous tiny scattered subcutaneous superficial nodules are noted, compatible with neurofibromas.There is increased signal intensity within the right anterior femoral head/neck junction which was not seen on the prior study and likely represents a focus of bone marrow edema.
No significant change in size of the sacral nerve root lesion.
