Hyperviscosity syndrome with pulmonary involvement.

ABSTRACT

A 44-year-old male presented with dizziness, blurring of vision, unproductive cough, dyspnoea, heaviness of head, fever and hepatosplenomegaly along with reticulonodular infiltration in chest x-ray. His serum showed monoclonal IgM gammopathy. Peripheral blood smear, bone marrow examination and serum protein electrophoresis suggested it was a case of Waldenstrom's macroglobulinaemia. Chest x-ray and CT scan of thorax were suggestive of pulmonary involvement in the form of interstitial lung disease.
