This case report describes a traumatic pseudoaneurysm arising from the right V4 segment of the vertebral artery, near the origin of the posterior inferior cerebellar artery. Post-traumatic vertebral artery pseudoaneurysm is rare, but associated with a high mortality rate. We report on an extremely rare case of post-traumatic pseudoaneurysm of the vertebral artery with delayed manifestation. A 9-year-old child was admitted to the emergency room after a pedestrian car accident. A computed tomography (CT) scan showed subarachnoid hemorrhage with intraventricular hemorrhage (IVH), multiple facial bones, and temporal bone fracture. External ventricular drainage and decompressive suboccipital craniectomy were performed for acute hydrocephalus and posterior fossa swelling. The patient's clinical condition became suddenly aggravated on the 15th hospital day, and brain CT confirmed appearance of a new 4th ventricle IVH. Digital subtraction angiography revealed a ruptured pseudoaneurysm arising from the right V4 segment of the vertebral artery. Parent artery occlusion using detachable coils was achieved. Despite intensive care, the patient's clinical condition showed continuous deterioration and the patient died of respiratory complications on the 52nd hospital day.
