A 59-year-old woman with chronic hepatitis C presented with abdominal pain. She received warfarin for portal vein and superior mesenteric vein thrombosis and developed a severe headache with nausea, vomiting, and right-sided weakness. CT of the brain showed left frontoparietal intracranial bleeding. Warfarin was discontinued. Routine abdominal ultrasonography for hepatoma surveillance found new infiltrative liver lesions. Biopsy revealed hepatocellular carcinoma. The patient was referred for tumor embolization. Before the start of treatment, the patient developed severe right-sided headache, nausea, and vomiting, with visual field defect. Emergency CT of the brain revealed a hemorrhagic lesion in the right superior parietal lobe cortex/subcortex. MRI of the brain revealed a right posterior parietal lobe hematoma.
