Images obtained in a 75-year-old woman who fell at home and presented with nausea, vomiting, and lethargy. On neurologic examination, she was lethargic but arousable, opening her eyes, responding to voice, and following simple commands. She had a right-sided Babinski sign and a GCS score of 14. Her medical history was significant for atrial fibrillation, for which she was receiving coumadin. Nonenhanced CT scan shows a right cerebellar hemorrhage that extends into the fourth ventricle (arrow). The patient’s coagulation status was reversed with vitamin K and fresh frozen plasma. A few days later, she developed hydrocephalus, which responded to treatment with a ventriculostomy tube. Her condition improved, and she was discharged to a skilled nursing facility.
