Distribution of femoral metastases; potential role for extended FDG PET/CT scanning.

This study investigates the distribution of femoral metastases in cancer patients, specifically addressing the incidence of distal femoral metastases. PET/CT examinations routinely extend only to mid-thigh level, precluding detection of distal metastases. We found a total of 208 femoral metastases in 112 patients. 30% had distal femoral metastases in addition to other areas of involvement. 7% of patients with femoral metastases had only distal femur disease. 6 patients had distal pathologic fractures. Exclusion of the distal femur during PET/CT may result in a missed or delayed diagnosis that could contribute to the development of a pathologic fracture with increased morbidity.
