A patient with Streptococcus pneumoniae aortitis is
presented. Because of nonspecific symptoms (fever and
back pain) there was a long diagnostic delay. In addition,
the aortitis was located near the renal arteries which
severely hampered early surgical treatment. Although
emergency surgery was performed when aortic rupture
occurred, the patient did not survive. Infectious arteritis of large vessels is a diagnosis often made late and associated with high mortality.
