Iliopsoas abscess as a complication of tunneled jugular vein catheterization in a hemodialysis patient.

Iliopsoas abscess is a rare complication in hemodialysis patients that is mainly due to adjacent catheterization, local acupuncture, discitis, and bacteremia. Herein, we report a 47-year-old woman undergoing regular hemodialysis via a catheter in the internal jugular vein who presented with low back pain and dyspnea. A heart murmur suggested the presence of catheter-related endocarditis, and this was confirmed by an echocardiogram and a blood culture of methicillin-resistant Staphylococcus aureus. A computed tomography indicated a pulmonary embolism and an incidental finding of iliopsoas abscess. Following surgical intervention and intravenous daptomycin, the patient experienced full recovery and a return to usual activities. This case indicates that an iliopsoas abscess can be related to a jugular vein catheter, which is apparently facilitated by infective endocarditis. The possibility of iliopsoas abscess should be considered when a hemodialysis patient presents with severe low back pain, even when there is no history of adjacent mechanical intervention.
