Intracranial hemorrhage from undiagnosed metastatic brain tumor during general anesthesia.

A patient with endometrial cancer presented with intracranial hemorrhage from an undiagnosed metastatic brain tumor during abdominal radical hysterectomy. Since she was neurologically intact, a systematic examination for brain metastasis had not been performed preoperatively. After the surgery, she had delayed recovery from general anesthesia with right hemiplegia and aphasia. Computed tomography and magnetic resonance imaging showed left putaminal hemorrhage from brain metastasis.
