Acute noncrescentic poststreptococcal glomerulonephritis presenting with pulmonary hemorrhage

We report a child with acute poststreptococcal noncrescentic glomerulonephritis and pulmonary hemorrhage. This patient demonstrates that: (1) poststreptococcal noncrescentic glomerulonephritis in children can be associated with pulmonary hemorrhage, (2) an expeditious renal biopsy in patients with acute or rapidly progressive glomerulonephritis and pulmonary hemorrhage can establish an early diagnosis and provide timely guidance for treatment, and (3) although not proven by controlled studies, the intravenous administration of methylprednisolone in our patient may have been effective in the treatment of pulmonary hemorrhage.
