Dynamic CT perfusion was performed in two patients with newly developed fixed dilated pupils and similar CT findings of multiple intracranial haematomas and impending transtentorial herniation. CT perfusion in case 1 showed severely reduced supratentorial and mesencephalic haemodynamic parameters. The patient died at the same day. CT perfusion in case 2 revealed physiologic perfusion parameters. Emergency bifrontal decompressive craniectomy was performed through which intracranial pressure was successfully lowered. This patient took a satisfactory clinical course. These results demonstrate that besides stroke as its main field of application, dynamic CT perfusion can also be performed in patients with critically raised intracranial pressure to obtain quick information's about tissue viability.
