Abstract

PET & PET/CT are increasingly being used for oncologic imaging. In lung cancers, FDG PET/CT is performed to stage the disease at initial presentation, assess response to conservative therapy and to detect recurrence following treatment. A 53 year old male, operated for resectable carcinoma lung, underwent a follow up PET/CT scan, six months after the surgery. PET/CT images were highly suggestive of a malignant lesion in the chest wall. Excision biopsy revealed a suture granuloma. The case highlights an uncommon but potential cause for false positive on FDG PET/CT, in cancer patients evaluated following a surgical intervention.
