Pak J Med Health Sci Jan ;13(1):188-9.

A young man presented with chest pain was found to have Myocardial Infarction (MI). Patient already had two episodes of MI in last 3 months. Examination showed findings consistent with Bilateral pleural effusion. Investigations showed hematuria, proteinuia along with deranged renal function tests and segmental wall motion abnormalities along with reduced ejection fraction on coronary angiography. Further investigations revealed positive MPO-ANCA. These features were suggestive of Microscopic polyangiitis, one of the renopulmonary syndrome. Patient showed dramatic improvement on steroid therapy with marked improvement in pleural effusion and renal function tests on follow up.
