I had an MRI for significant increasing pain in my back and across by left side of chest for 3-4 months. The MRI resulted in a differential diagnosis of metastatic process or multiple myeloma. A bone scan "lit up" my sternum/clavicle, T5 vertebrae and left knee (also had sudden onset of pain there with no prior injury). The CT showed cortical scalloping at the T5 and nodules on my lungs (they are not worried about those). The sternum was not viewed on CT. The PET showed hypermetabolic activity at the sternoclavicular joint. The T5 did not show up on PET. My primary doc, who has had conversations with the MRI and bone scan radiologist told me that they were adamant that it was not inflammation. Now I'm being told by my onc that the PET said it is typical of inflammation since it's in the joint (but the report also said that the area correlated with areas of abnormalities on the MRI) so we are not going to do anything. I know that spinal metastatic processes are often not noted on PET, so now I'm wondering if I'm going to be told 6 months from now that it was not inflammation after all. I have been told for a month that the radiologists for the bone scan and MRI told my primary care that they should be "looking for a primary tumor" and now I'm told it's inflammation. Has anyone else experienced this and what was the outcome??? THANKS
