This is a vasculitis of the small- and medium-sized arteries and is more common in males.
Fever, malaise and weight loss are almost always present, due to ischaemic complications.
Most (80%) have renal involvement.
The gastrointestinal (GI) tract is affected in about 60%.

CT/INTERVENTION
• 1-5-mm microaneurysms, typically peripheral and intra-renal.
• Aneurysms tend to occur where vessels bifurcate.
• Stenoses also occur.
• Vasculitis causes distal ischaemia (renal infarcts, gut ischaemia, etc.).
• May present with haemorrhage.
