Thanks everyone. Oh, and as for Tammy's comment, I should have been clearer, I had nothing to do with convening the tumor board, that was my RO's doing. He's the one with the arsenal. He felt that the edema issue had not been fully explored since until me, nobody else at this CCC had ever had this much radiation over the maximum. So there was no true comparisons for the radiologist to consider. That's why the language was so scary:

[quote]Impression: Persisting abnormal soft tissue in the left parapharyngeal space with extension along the left/middle hyoid bone compatible with known recurrent tumor. These areas were hyper-metabolic on prior Pet study.

Findings: There continues ill-defined soft tissue prominence with loss of myofscial planes in the left parapharyngeal space which was hypermetabolic on PET study, likely presenting a combintion of tumor and post treatment changes. There is persisting abnormal soft tissue, extending along the left/central hyoid bone which demonstrated bony erosion and hyper-metabolic activity on prior PET compatible with neoplasm

After going over the MRI with the tumor board, the radiologist reconsidered and felt that post radiation edema was more likely than a tumor combo. They did schedule another MRI in mid April plus a 6 month post TX PETscan that same week in April.
But I will worry about those in April.
Boy, did I give Dr. Google a workout yesterday looking up all those medical terms and then articles to put them into context.
