PET scan since treatment

Hello ladies, just wondering if anyone had the aortocaval lymph node come up on a PET scan and it was nothing??

I had my hysterectomy for stage 1 almost a year ago. Pathology came back with a node that was impacted and put me in stage 3C1.

Had cisplatin and pelvic radiation which I finished almost 9 months ago. I’m also on immunotherapy with Keytruda until June 2027.

My latest pet scan came back with a new FDG avid aortocaval lymph node (SUV max 2.0) and I’m freaking out!!!

Just curious if any of you experienced this and it was nothing to worry about, just inflammation.

Thank you 🙏🏼
