A Case of Pulmonary Hemorrhage Associated with IgA Nephropahty in Adult / 대한신장학회잡지

ABSTRACT

IgA nephropathy is the most common glomerulonephritis in all parts of the world. It presents as asymptomatic microscopic hematuria or proteinuria or as episodic gross hematuria after upper respiratory infection or excercise. Pulmonary hemorrhage is both a rare complication and presentation of IgA nephropathy. We report a case of pulmonary hemorrhage associated with IgA nephropathy in adult. A 29-year-old woman was transferred because of gross hematuria and hemoptysis after hysterectomy. Chest X-ray showed bilateral pulmonary infiltrates in lower lobes. Renal biopsy showed mesangial expansion by mesangial cellular proliferation with mesangial staining of IgA. Her repiratory symptom and pathcy opacities on the chest X-ray disappeared spontaneously. Normal renal function of the patient maintained but she had persistent hematuria.
