44 year old female with known diagnosis of anaplastic astrocytoma. Redemonstrated is increased FLAIR/T2 signal intensity in the left parietal lobe precuneus extending through the left caudate nucleus to the left lateral ventricle wall appearing similar to prior study. There is persistent internal enhancement which overall appears stable or slightly decreased extent of enhancement especially along the anterior aspect of the tumor. There is some stable intrinsic T1 signal within the region of enhancement. There are some internal foci of low signal on susceptibility weighted imaging which appear similar to the prior study. No new intraparenchymal lesion, new enhancement or new signal abnormality is identified elsewhere in the brain. There is mild expansion of the trigone of the left lateral ventricle similar to prior exam with no mass effect or midline shift. The ventricles are otherwise unchanged. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
Stable or slightly decreased extent of enhancement of the left parietal lobe precuneus located infiltrative lesion compatible with anaplastic astrocytoma. Subsequent follow-up exams should include dedicated perfusion imaging sequences.
