Alternative Names

Midline granulomatosis

Definition of Wegener's granulomatosis:

Wegener's granulomatosis is a rare disorder in which blood vessels become inflamed, making it hard for blood to flow.

Causes, incidence, and risk factors:

Wegener's granulomatosis mainly affects blood vessels in the nose, sinuses, ears, lungs, and kidneys, although other areas may be involved.

The cause is unknown. It is thought to be an autoimmune disorder.

Wegener's granulomatosis is most common in middle-aged adults. It is rare in children, but has been seen in infants as young as 3 months old.
