 There is a 6 mm solitary, focal, ovoid T2 hyperintensity within the mid right temporal lobe without associated mass effect, restricted diffusion, or susceptibility abnormality (best seen series 801, image 16/25). This was not present on the 2009 brain MRI.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear.
There is a 6 mm solitary, focal, ovoid T2 hyperintensity within the mid right temporal lobe without associated mass effect, restricted diffusion, or susceptibility abnormality. This was not present on the 2009 brain MRI. This is nonspecific in appearance, and given its solitary nature is of uncertain etiology or significance and would be an unusual appearance of neuroblastoma metastasis. Recommendations are made to repeat MRI, with contrast, in 3 months to assess for stability.
