Accurate and reliable staging of disease extent in patients with malignant MM is essential to ensure appropriate treatment planning. The detection of recurrent or residual malignancy after primary treatment is important to allow for early intervention and to optimise patient survival. 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG) PET or PET computed tomography (PET/CT) is indicated for surveillance of malignant MM due to its high sensitivity and specificity for soft-tissue or nodal recurrences and metastases. It has been claimed that including lower extremities and skull in addition to 'eyes to thigh' images in PET/CT evaluation of metastatic MM routinely is warranted. We have studied retrospectively the reports of whole-body PET/CT scans in all patients with MM scanned in our Department from April 2005 to December 2010. ⋯ In conclusion, whole body PET/CT scan showed about 1% unexpected primary or metastatic MM lesions involving the head or lower extremities, which seldom offered significant additional clinical benefit and were unlikely to change clinical management. No clinically significant change in staging would have occurred. Routine 'eyes to thighs' images were adequate for this subset of patients.
