large vessel vasculitides
Combined
modality PET/MR for the detection of severe large vessel vasculitis. PET, MR, and PET/MR images. The MR, PET, and combined PET/MR findings in a patient with severe LVV (top row) presenting with a multi-year history of aching in bilateral legs and a stabbing pain in bilateral calves, and in a patient with non-severe LVV (bottom row), presenting with arthralgia and chronic constipation. Arrows point to an example vessel-of-interest in a severe LVV patient with positive PET and MR findings (at the ascending thoracic aorta) and in a non-severe LVV patient with positive MR findings (at the descending thoracic aorta). Positive MR findings more effectively ruled-in severe disease compared to PET, while negative PET findings more effectively ruled-out severe disease compared to MR

The term large vessel vasculitis (LVV) usually denotes the spectrum of primary vasculitides that causes chronic granulomatous inflammation predominantly involving the aorta and its major branches.
Pathology
The two major entities in this group are
- giant cell arteritis (GCA): affects older individuals (typically over 50)
- Takayasu arteritis (TA): affects younger individuals (typically under 50)
There are, however, many other conditions that can potentially involve large caliber vessels. These include:
- Hughes-Stovin syndrome
- Kawasaki disease
- Behcet syndrome
- rheumatoid arthritis
- syphilis
- tuberculosis
- isolated angiitis of the central nervous system
