Psoas abscess in a female diabetic patient. Case presentation

Abstract

The abscess of the iliac psoas muscle uses to be the infrequent cause of unknown origin fever in healthy patients. Nevertheless, its incidence increases in patients who carry debilitating diseases as diabetes mellitus. The case presented deals with a female diabetic patient showing fiver of unknown origin already for six months, with final diagnosis of psoas abscess. The patient, aged 57 years, has type I diabetes mellitus, complicated with bilateral obstructive lithiasic uropathy and reiterative urinary infections. At the age of 33, she was operated of pyonephrosis and right renal abscess secondary to ascendant urinary infection by Klebsiella pneumoniae. She was operated again for recidivist abscess to Klebsiella, acquired through the urinary tract, but this time it was an abscess contiguous to left iliac psoas muscle, after a six-month evolution period of unknown origin fever. The unusualness of this case consists in the recidivism of deep retroperitoneal abscesses by Klebsiella and the insidious presentation form of the current psoas abscess.
