Staphylococcus Aureus is a Gram-positive cocci bacteria
which had been found to be the causative organism in over
88% of patients with primary iliopsoas abscess. We report
the case of a 53-year-old diabetic woman with end-stage
renal failure diagnosed with left iliopsoas abscess with a
catheter-related infection. Computed tomogram (CT) of
abdomen and pelvis revealed hypodense lesions of left
psoas, iliacus and quadratus lumborum suggestive of psoas
abscesses. In addition, osteomyelitis changes at left
sacroiliac and hip joint were seen. At surgery, she was found
to have abscess at the posterior psoas muscle where she
underwent open surgery drainage and percutaneous drain
was inserted. A high index of suspicion of iliopsoas abscess
should be maintained among haemodialysis patients
presenting with intradialytic pelvic and hip pain and treated
with optimal antibiotics therapy with appropriate surgical
intervention.
