Question: Diffuse Large B Cell Lymphoma – Primary Mediastima : abnormal non mass like circumferential mucosal hyperdensity present

Hi, my 17 year old son was diagnosed with Diffuse Large B Cell Lymphoma – Primary Mediastima last August. He went through a 6 cycle regimen of r-chop and completed in Jan. He had a PET/CT scan done in Feb which showed the cancer had decreased enough to claim success (went from 9.5 X 5.9 cm and nodes in lung, neck & armpit to 3.9 X 2.8 cm with nodes gone). He went back in for a CT scan in May and they found no real difference in the mass measurement but they did find in the mediastinum an “abnormal non mass like circumferential mucosal hyperdensity present in the esophagus throughout the thorax, most conspicuously in the region of the thoraci inlet and upper mediastinum, significantly increased compared to prior scan”. My question is, would this concern you? Would you want to do any follow up tests? Do you believe it is heartburn (my son has no symptoms of heartburn)? Given his history of cancer is there a chance this is related to cancer or even cancer again?
