Pain after prosthesis implant is a common clinical problem which requires distinction of septic from aseptic causes since the treatment differs. Non-invasive imaging methods play an important role in the diagnosis. Radiolabelled ubiquicidin can be used for imaging infection by binding directly to bacterial cell wall. We describe a case of a 24-year-old man with right lower limb megaprosthesis which did not show any loosening on computed tomography (CT) but was accurately diagnosed as infected prosthesis with 68Ga-NOTA-ubiquicidin(29-41) acetate scan.
