Polyarteritis Nodosa (PAN) can be associated with chronic myelomonocytic leukaemia (CMML).
Spontaneous bilateral renal haemorrhage as the initial manifestation of PAN in association with CMML is a rare condition.
Early diagnosis and treatment is vital for patient’s survival.
Normal renal function can be regained with early artery embolization, steroids and cyclophosphamide treatment.
