A 65-year-old man comes to the emergency department due to sudden onset headache. The patient has not had any recent falls or head trauma. His past medical history includes hypertension and lung adenocarcinoma with abdominal metastasis. His initial noncontrast head CT reveals a small temporal lobe hemorrhage. Over the next 24 hours, he becomes progressively obtunded and develops generalized tonic-clonic seizures. His blood pressure is 190/96 mm Hg, pulse is 38/min, and respirations are 6/min with brief episodes of apnea. A repeat noncontrast head CT reveals acute hematoma expansion with brain herniation.
