A 74 year-old man presented with new onset atrial fibrillation and the acute loss of vision on the right side. CT scan of the brain was normal on admission. Two days later, he developed a headache, nausea and vomiting accompanied by a decreased level of alertness. |
| Hemorrhagic Transformation of an Ischemic Infarction. Axial CT scans two days after presentation. Note the large hemorrhage in the left occipital lobe, surrounded by some vasogenic edema. In this case, the patient presumably had an embolic infarction due to atrial fibrillation, with the embolus occluding the left posterior cerebral artery. In this case, the ischemic infarct turned hemorrhagic two days after presentation. In some cases, ischemic infarcts may turn hemorrhagic, with or without anticoagulation. |
