Polyarteritis nodosa

Presentations

Appropriate Tests

 

Systemic necrotising vasculitis involving medium sized muscular arteries and associated with aneurysm formation.

The diagnosis is made on the basis of clinical assessment, diagnostic imaging procedures and/or biopsy of an appropriate site.

Creatinine, Electrolytes to assess extent of disease; C-Reactive protein or Erythrocyte sedimentation rate to assess activity of disease. Antineutrophil cytoplasmic Ab (ANCA) contribute to the clinical assessment in the differentiation of PAN from ANCA positive vasculitides - (eg microscopic polyangiitis and granulomatosis with polyangiitis) which have a broader range of vessels.
