Bone scan shows uptakes at ribs
My mother was just diagnosed with ILC. Biopsied tumor is on the left side. Skin and chest wall are involved so the oncologist is trying to determine metastases now. He ordered a bone scan and chest/abdomen/pelvis CT. Bone scan shows 2 focal mild to moderate uptakes on 2 of the right ribs. Without CT correlate. Impression is "cannot exclude osteoblastic metastases to the right ribs. Consider follow-up bone scan in 3 months, or radiographs earlier if either side becomes symptomatic". She feels chest pain both sides from time to time.
Is this any further imaging exam to confirm this? I read that PET-CT is most accurate but she just took a CT (allergic to CT contrast dye, used Prednisone / Benadryl protocol), so that's a lot of radiation in a short period of time. Is chest MRI a good next step? She had a breast MRI coming up but does it do the same as a chest MRI?
Also how accurate is the CT in regards to bones and organs? It says a few low density lesions on liver and kidney are too small to definitively characterize, and also notes nodular thickening of adrental gland and thickening bladder wall. I read that ILC can have uncommon metastatic sites. What could be the next step to investigate these further? Does MRI work well for abdomen and pelvis areas?
Any suggestions are welcome. Thank you! And wish everyone a happy and healthy new year!
