The definite diagnosis of vasculitis is established after a biopsy of involved organ or tissue, such as skin, sinuses, lung, nerve, brain, and kidney. The biopsy elucidates the pattern of blood vessel inflammation. Some types of vasculitis display leukocytoclasis, which is vascular damage caused by nuclear debris from infiltrating neutrophils. [37]
The disease spectrum varies from failure of multiple organs to involvement of a single organ. Almost any organ could be impacted; however, polyarteritis nodosa rarely affects the lungs for unknown reasons. [10] Kawasaki disease (KD) is a type of systemic vasculitis of medium-sized vessels with an acute onset that primarily affects young children.
It is an autoimmune disease and a form of vasculitis that affects small- and medium-sized vessels in many organs, but most commonly affects the upper respiratory tract, lungs, and kidneys. [6] The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels.
These vasculitis diseases typically affect a wide range of muscular arteries that supply organs, which gives the conditions a wide range of possible symptoms. The most common type of all vasculitides is Kawasaki disease, and we’ve got a separate video on Kawasaki disease, but for now it’s important to note that it affects the coronary ...
The most frequent presenting signs and symptoms of primary CNS vasculitis were focal neurological defecits (seen in 63% of cases), headaches (51%) and cognitive impairment (41%). [4] Other presenting symptoms include aphasia or other difficulties with speech (35-43%), ataxia , visual field deficits, acute or subacute encephalopathy (which may ...
Small vessel cutaneous vasculitis is a diagnosis of exclusion and requires ruling out systemic causes of the skin findings. [14] Skin biopsy (punch or excisional) is the most definitive diagnostic test and should be performed with 48 hours of appearance of the vasculitis. [ 6 ]

Retinal vasculitis is inflammation of the vascular branches of the retinal artery, caused either by primary ocular disease processes, or as a specific presentation of any systemic form of vasculitis such as Behçet's disease, sarcoidosis, multiple sclerosis, or any form of systemic necrotizing vasculitis such as temporal arteritis, polyarteritis nodosa, and granulomatosis with polyangiitis, or ...
