FDG-PET/CT was ordered in 10 out of 68 solid tumor patients with pathologically proven BMM. Of these 10 patients, 3 were female and 7 were male; mean age was 54.7 years (range 24 - 69). While FDG PET/CT showed bone and BMM in 4 of 10 patients (40%), the rest of the patients had BMM without bone involvement. In other words BMMs were detected in all of our patients. There was a wide variation of tumor types. The characteristics of the patients are presented in Table 1. Five patients (50%) who had probable bone marrow involvement on their FDG PET/CT scans had unsuspected complete blood counts with regard to BMM. Bone marrow biopsies showed 5 adenocarcinoma, 4 of which were mucinous in type, 1 sinonasal cancer, 1 rhabdomyosarcoma, 1 small cell lung cancer, 1 large cell lung cancer and 1 breast carcinoma.
