Answer

Imaging study findings are as follows:

  • Sacroiliitis may be observed on a radiograph, magnetic resonance imaging (MRI) scan, or computed tomography (CT) scan
  • Radiographs of peripheral joints may show soft-tissue swelling and/or effusions
  • Brain CT scanning may identify areas of acute ischemia
  • Brain MRI/magnetic resonance angiography (MRA) can identify cerebral vasculopathy and areas of acute/subacute ischemia (see the images below)
  • Single-photon emission computed tomography (SPECT) has been used to identify areas of cerebral hypoperfusion.
  • Angiography may be used to evaluate for aneurysms
