History of grade II oligodendroglioma status post resection, radiation and chemotherapy, now with progression. This is a limited MRI of the brain for presurgical planning. There are postoperative findings related to right craniotomy with confluent high T2 signal surrounding the resection cavity. In particular, there is interval enlargement of an ovoid T2 hyperintense lesion in the anterior right frontal lobe, which measures 24 x 16 mm, previously 15 x 9 mm. In addition, there is an associated cluster of ring enhancing components. The ventricles are unchanged in size and configuration. There are skin-based fiducial markers.
Pre-treatment planning MRI for an enlarging right frontal lobe lesion.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
