Description
Erin A. Dean and co-authors described a single patient case in 2026 involving diffuse large B-cell lymphoma treated with the standard R-CHOP regimen. After six full cycles, scans showed growing tracer uptake in the woman's original abdominal mass, raising fears the lymphoma had resisted treatment.
Further imaging, biopsies, and sensitive blood tests for leftover disease found no active lymphoma. The bright scan signal came from fibrosis, scar-like tissue left by treatment, and it faded on later scans with no extra therapy. The case warns that scarring can imitate worsening disease on PET/CT scans, and checking before starting stronger treatment can spare patients needless harm.
