 This exam is degraded by motion artifact.There are unchanged postoperative findings with residual pneumocephalus related to placement of a right frontal approach catheter within a right basal ganglia hematoma. The overall cavity size is unchanged, as is the acute hematoma, currently measuring 52 x 37 mm. There is grossly unchanged surrounding edema. There is again blood layering within both lateral ventricles as well as minimal left parietal subarachnoid hemorrhage. There is unchanged 10 mm leftward midline shift. The ventricles are unchanged in size with questionable mild dilatation of the left lateral ventricle. There is susceptibility effect compatible with chronic microhemorrhage in the left basal ganglia and thalamus. There is no evidence of acute infarct. There are scattered patchy foci of T2 hyperintensity throughout the supratentorial and infratentorial white matter that are most compatible with chronic small vessel ischemic disease. Mild asymmetric T2 hyperintensity within left dentate nucleus is nonspecific but may also represent chronic small vessel ischemic disease. There is mild ectasia of the distal right internal carotid artery. The major cerebral flow voids are intact. There is minimal fluid within the mastoid air cells.
1.Essentially unchanged postoperative findings related to placement of a catheter within a right basal ganglia acute hematoma with surrounding edema and intraventricular extension. The size of the hematoma and the associated midline shift is unchanged. 2.The ventricles are unchanged in size with questionable mild dilatation of the left lateral ventricle.3.Unchanged mild left parietal subarachnoid hemorrhage.
