• Diagnosis
• Hemorrhage from small aneurysms in the kidney
  due to Poly arteritis nodosa (PAN)
• Poly arteritis nodosa (PAN) is a systemic
  vasculitis with a male female ratio of 21 and a
  peak incidence in the fifth decade. Small to
  medium-sized arteries are involved by focal
  transmural inflammatory necrosis. Aneurysms with
  inflammatory destruction of the media also occur.
  The most frequently involved organs are the
  kidney, heart, lung, liver, and gastrointestinal
  tract.
• There is no place here for Interventional
  Radiology or embolisation unless the patient is
  in deep shock and a nefrectomy is planned, and
  the patient is too ill for surgery. Embolisation
  of the renal artery might then be a rare option.
  Usually the patient is treated with high-dose
  cyclophosphamide and steroids for 6 months and is
  than continued on low-dose cyclophosphamide until
  the vasculitis is cured.
