A 31 year-old male patient received the following vaccines on 17 June 2009: a percutaneous injection of ACAM2000 (lot number VV04-003) and YF-VAX (lot number UF434AA). The sites of administration were not reported. It was reported that the patient was well on the day of and prior to vaccination. He developed new onset daily headaches 1-2 days later, rated 5 out of 10 on a pain scale and self-treated with TYLENOL as needed. The patient reported no visual disturbance or any other neurologic, systemic or constitutional symptoms, except a single isolated brief episode of mental lapse described as "forgetting to make planned left turn" at a usual familiar intersection. The patient had normal take at his smallpox vaccination site. It was also reported that the patient received a first dose of Anthrax vaccine and MGC vaccine on 11 June 2009 (6 days prior to smallpox vaccination).

A head CT on 24 June 2009 revealed small left occipital condyle fracture with subarachnoid hemorrhage and small falx subdural hematoma; also had right clavicular comminuted fracture. Brain MRI on 26 June 2009 revealed grade II diffuse axonal injury involving splenium of corpus callosum and white lobar matter; FLAIR sequences demonstrated residual blood byproducts in falx; electroencephalogram on 28 June 2009 was normal.
