title: An unusual cause of hemoptysis.
abstract: Xanthogranulomatous pyelonephritis is a renal inflammatory process associated with chronic obstruction and renal calculi. A patient with xanthogranulomatous pyelonephritis presented with the acute onset of hemoptysis and a lung mass. At thoracotomy the mass was resected and found to be a renal calculus embedded within inflammatory tissue.
