Description

Wegener’s granulomatosis (also known as granulomatosis with polyangiitis) is a type of vasculitis that affects small and medium blood vessels. Symptoms can include saddle nose deformity, chronic sinusitis, and collapsed trachea. Microscopic polyangiitis is similar to wegener’s granulomatosis except it only affects small blood vessels in the lungs or kidneys. Learn how the presence of granulomas and antibodies (cANCA and pANCA) differentiate these two conditions.

Vasculitis

Inflammation of the blood vessel wall is termed “vasculitis,” though the etiology of these diseases are rather nebulous. They present with nonspecific symptoms like fever, fatigue, weight loss. Large, medium, and small vessels can all be involved. We will explore the specific differences between the various vasculitides, which range from Takayasu arteritis to microscopic polyangitis.
