[Brain stem infarction, temporal headache, and elevated inflammatory parameters in a 74-year-old man].

We report the case of a 74 year old man with a brain stem infarction, temporal headache and elevated inflammatory parameters. Giant cell arteritis with involvement of the temporal and vertebral arteries was proven by histology, duplex sonography and MRI. Although intensive immunosuppressive therapy was started, the patient developed two brain infarcts within 6 months. Initially, C‑reactive protein and erythrocyte sedimentation rate were significantly elevated, but normalized over time. Involvement of the vertebral artery in giant cell arteritis is thought to be rare; steroid refractory courses are very rare. Brain stem infarction might be the consequence.
