Behget disease is a multi-systemic immune-mediated vasculitis affecting both arteries and veins, more common (by four- to five-fold) in young Men.
The classic presentation is with a triad of oral ulceration, genital ulceration and ocular inflammation.
CT
• Cardiovascular system involved in up to 30%. Look for aortic pseudoaneurysms and occlusion/stenosis of distal vessels.
• Pulmonary artery aneurysms and haemorrhage.
MRI
• Central nervous system (CNS) involved in up to 20%.
• The best indicator is a brainstem/basal ganglia lesion (bright on T2) in the right clinical context.
