Subdural hematoma. This 69-year-old woman with Parkinson disease underwent bilateral subthalamic nucleus DBS placement. Intraoperative MR imaging revealed a right 8-mm subdural hematoma characterized as isointense (arrows) on both T2* GRE (A) and T1 MPRAGE (B) sequences. The lesion displayed high signal intensity (arrow) on FLAIR imaging (C). Computed tomography confirmed the presence of a subdural hematoma (arrow, D).
