Suture granuloma formation can cause abnormal radiotracer uptake of 2-deoxy-2-[18F] fluoro-D glucose (FDG) in positron emission tracing/computed tomography (PET/CT) scan. It can be formed secondary to usage of silk suture during surgery as part of delayed host inflammatory reaction to a foreign body. Here, we report a case of a 61-year-old woman diagnosed with endometrial cancer who underwent tumor debulking surgery secondary to abnormal radiotracer uptake in PET/CT suspected as tumor recurrence which on histology revealed suture granuloma.
