Ruptured renal microaneurysms complicated with a retroperitoneal abscess for a patient with systemic lupus erythematosus.
Renal artery aneurysm is extremely rare among patients with systemic lupus erythematosus.(SLE). Herein, we report on a 22-year-old male lupus patient who presented with acute abdominal pain, anemia and subsequent hypertension. Abdominal computed tomography revealed a peri-renal hematoma over the right kidney. A renal angiography revealed bilateral renal microaneurysms. The patient subsequently developed a right-side retroperitoneal abscess 4 weeks after hematoma formation and received an emergent laparotomy with drainage. Subsequent culture ofthe abscess-derived fluid revealed the presence of Proteus mirabilis and Escherichia coli. Following appropriate antipyretic and immunosuppressive drugs therapy, the patient recovered successfully. To the best of our knowledge, this is the first report of SLE associated with a retro-peritoneal abscess probably secondary to a ruptured renal microaneurysm.
