technetium-tc-99m-medronate and Thymus-Neoplasms

We present a case of thymic carcinoid, in which primary and metastatic lesions of lymph nodes and bones could be detected by [(18)F]fluoro-2-deoxy-D-glucose (FDG)-PET, but not by (123)I-meta-iodobenzylguanidine ((123)I-MIBG) SPECT, or by (99m)Tc-methylene diphosphonate ((99m)Tc-MDP) bone scintigraphy. FDG-PET may be a useful tool for managing thymic carcinoids in patients with negative results on (123)I-MIBG SPECT or (99m)Tc-MDP imaging.
