A patient with tongue cancer undergoing restaging PET/CT scan incidentally found a foreign body in the colon. The foreign body was successfully removed via colonoscopy, highlighting an unexpected finding during cancer follow-up.
Area of Science:
- Oncology
- Gastroenterology
- Nuclear Medicine
Background:
- A 78-year-old woman presented with unresectable tongue cancer.
- The patient received radiation therapy and experienced dysphagia requiring prolonged enteral nutrition.
Purpose of the Study:
- To perform restaging of tongue cancer using 18F-FDG PET/CT.
- To investigate incidental findings during the PET/CT scan.
Main Methods:
- 18F-FDG PET/CT imaging for cancer restaging.
- Colonoscopy for removal of detected foreign body.
Main Results:
- PET/CT revealed a left cervical node uptake, indicative of cancer recurrence.
- An unexpected focal uptake in the descending colon was identified, corresponding to a foreign body.
- The foreign body was successfully removed by colonoscopy.
Conclusions:
- 18F-FDG PET/CT can identify unexpected findings beyond the primary cancer.
- Incidental colonic foreign bodies can be detected and managed endoscopically.
- This case highlights the importance of thorough image interpretation in cancer patients.
