Iinfiltrating grade 3 astrocytoma status post radiation and chemotherapy. Evaluate for interval change. There is a mildly expansile and infiltrative T1 hypointense and T2 hyperintense lesion within the left pons, mid brain, extending into the left thalamus, with no evidence of enhancement or diffusion restriction, which is unchanged. The nonspecific trace T2 hyperintensity in the right pons appears unchanged. Likewise, other scattered areas of nonspecific cerebral white matter T2 hyperintensity appear to be unchanged. There is postoperative findings within the right cerebellum with focal tissue loss, but no discernible mass lesions. There are several nonspecific punctate foci of susceptibility scattered throughout the brain parenchyma, which are unchanged. There is no evidence of acute ischemia. The ventricles are within normal limits in size and configuration. The major cerebral flow voids are intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unchanged.
1.Unchanged appearance of the astrocytoma, with involvement of the left pons, midbrain and left thalamus and possible additional site within the right ventral pons.2.Postoperative findings within the right cerebellum without evidence of tumor progression.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
