Fig. 3From: The usefulness of 18F-FDG PET/CT for assessing methotrexate-associated lymphoproliferative disorder (MTX-LPD)Representative case of non-complete response group. Maximum intensity projection images of 18F-FDG PET/CT at initial examination (a), and second examination at 6Â months after MTX withdrawal (b) were shown. At the initial examination, an 18F-FDG-avid lesion was found at left neck (c; SUVmax 7.3, WBMTV 8.6Â ml, WBTLG 42.7Â ml). It was disappeared at the second examination after MTX withdrawal. However, at the second scan a recurrent lesion was found at left supraclavicular fossa (d) and radiotherapy was enforced. 18F-FDG uptake was confirmed at bilateral wrist joints, reflecting the reactivation of RA due to withdrawal of MTXBack to article page
