 There is a small collection posterior to the right paramedian cerebellum/sinus confluence which is relatively mid intensity on T1, hyperintense on T2, without enhancement, demonstrating no significant mass effect or susceptibility abnormality. This correlates with the previously identified hypodense fluid collection on the prior CT. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for acute cerebral, brainstem or cerebellar infarction. Flow voids are present within the major vessels indicating patency. The mastoid air cells are clear. There is no abnormal enhancement within the brain.

This is most suggestive of evolving subdural hemorrhage mixed with CSF.
