A 61-year-old woman with painful left knee prosthesis was investigated for septic loosening. In addition to prosthetic infection which presented as diffusely increased uptake surrounding left knee, a focally increased uptake below the medial side of right knee was noticed on 99mTc-HIG images. Although background and vascular activity were diminished at 24 hours after injection, the area of activity below the right knee was more apparent. We assumed this finding was due to soft tissue infection, however, a superficial varicose vein was shown by Doppler ultrasound. We conclude that varicose veins may be misinterpreted as a site of infection and thus may cause false positive results on 99mTc-HIG scintigraphy.en10.5336/medsci.2010-21640info:eu-repo/semantics/openAccessProsthesis failureradionuclide imagingvaricose veinssoft tissue infectionsArticle313763765WOS:000293108900041Q4Q4
