47 years, Male, questionable focus of increased activity in the right thalamus on PET. Newly diagnosed tonsil cancer. Multiple sequences are motion degraded. There is however no evidence of intracranial metastatic disease or signal abnormality in the thalamus. No restricted diffusion to suggest acute ischemia. No intracranial hemorrhage. No intracranial mass or mass-effect. The ventricles are within normal limits in size and configuration. Few scattered foci of T2/FLAIR hyperintensity are seen in the bilateral subcortical and periventricular white matter, which are nonspecific, but compatible with minimal chronic small vessel ischemic changes. Brain parenchyma is otherwise unremarkable for age. No abnormal parenchymal or meningeal enhancement. Major flow-voids are preserved.Sella and orbits are grossly within normal limits. Paranasal sinuses and mastoid cells are clear. Bone marrow signal is within normal limits. Right tonsillar mass and right cervical lymphadenopathy is partially imaged.
Brain parenchyma appears within normal limits for age. Specifically, no evidence of intracranial metastatic disease or signal abnormality in the right thalamus.
