Klebsiella pneumoniae-induced mycotic aneurysm of the abdominal aorta complicated by bloody pleural effusion--a case report.

Jpn Circ J 60(9):703-6 (1996) PMID 8902589

A 68-year-old diabetic male who suffered from recurrent severe lumbago and high fever was found to have mycotic abdominal aneurysm. His symptoms did not improve after maximum-dose antibiotic therapy. Bloody pleural effusion on the left side was noticed hours before he expired. Klebsiella pneumoniae alone was isolated from blood from cellulitis-related bacteremia, when aneurysm formation was complete and later from bloody pleural effusion. To our knowledge, this is the first report of mycotic abdominal aneurysm of solely Klebsiella pneumoniae complicated by bloody pleural effusion.
