AI Article Synopsis

  • Diagnosing prosthetic joint infections is challenging due to limitations in clinical signs, lab tests, and imaging techniques.
  • A patient with fever and hip prosthesis pain underwent Tc-sulesomab and F-FDG-PET/CT scans, which revealed high uptake and a fistula near the right hip.
  • Fistulography confirmed the presence of the fistula, leading to a successful fistulotomy for the patient.

Article Abstract

Diagnosing prosthetic joint infection is difficult; clinical signs and symptoms, laboratory tests, radiography, and joint aspiration are less sensitive and specific. We report a patient with fever and painful bilateral hip prosthesis, who underwent Tc-sulesomab scan showing moderate tracer uptake at the lateral surface of the right thigh and no signs of prosthesis infection. The F-FDG-PET/CT showed high uptake at the soft tissue of the right hip prosthesis and detected a fistula. Moreover PET/CT discovered an initial bone marrow involvement at the right femur. The subsequent fistulography confirmed the fistula, and the patient underwent definitive fistulotomy successfully.
