 FLAIR/T2 hyperintensity with susceptibility abnormality is consistent with the previously demonstrated bifrontal hemorrhagic contusions. Additionally, there is a much smaller focus of FLAIR/T2hyperintensity with susceptibility abnormality involving the lateral right temporal lobe, as well as subtle FLAIR/T2hyperintensity involving the anterior temporal lobes without susceptibility abnormality, also consistent with contusions. These latter lesions are not w readily apparent with previous CT technique.Expected evolution is noted involving small foci of subdural hemorrhage overlying the right frontal lobe as well as the left parietal lobe, with the latter propagating along the left tentorium. These do not have significant associated mass effect.The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There is no midline shift. There is no evidence for acute cerebral, brainstem or cerebellar infarction. Flow voids are present within the major vessels indicating patency. Fluid is again noted within left mastoid air cells. Scalp swelling is again evident over left and right calvarium posteriorly. Previously identified calvarial changes are not appreciated with MRI technique.Sagittal T1 fat saturation technique demonstrates a normal-appearing posterior pituitary lobe. The pituitary stalk appears intact without transection. The pituitary gland proper is normal in height.
