61 years Male (DOB:7/18/1954)Reason: ICH etiology History: cerebellar bleedPROVIDER/ATTENDING NAME: WENDY A. STOCK FERNANDO D. GOLDENBERG MRI of the brainThere is a 13 x 17 mm axial dimension hemorrhagic focus in the right cerebellar hemisphere associated with surrounding T2 and FLAIR signal hyperintensity compatible with vasogenic edema. Hemorrhagic focus is partially high signal on T1 and partially isointense to white matter on T1. It is heterogeneous signal on T2 imaging and has some susceptibility effect within it.There are is a punctate focus of susceptibility effect along the left frontal lobe subcortical white matter at the left middle frontal gyrus and another one at the subcortical white matter of the left orbital gyrusSmall amount of susceptibility effect is present along the posterior aspects of the trigones of the lateral ventricles.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate small mucous retention cysts.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact. The eyeball lenses are thin.MRA brain:The left posterior inferior cerebellar artery is partially visualized. The caudal tonsillar loop is obscured by lack of signal. It appears that the left posterior inferior cerebellar artery is dominant vessel which also supplies the vermis. The right anterior inferior cerebellar artery is also a dominant vessel and supplies part of the right posterior inferior cerebellar artery territory.No aneurysm or arteriovenous malformation is appreciated in connection with the patient's right cerebellar hemorrhage on this exam.Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified and is small to medium size. The posterior communicating arteries are small. The vertebral arteries are similar in size.
1.There is a right cerebellar hemorrhage present. There is no underlying lesion in the location identified on the prior MRI from 3/2/2016. There is a small amount of associated intraventricular blood identified.2.No evidence for intracranial aneurysm or arteriovenous malformation.3.There are couple microhemorrhages present in the left frontal lobe subcortical white matter, which in isolation would be difficult to considered to establish a specific pattern.
