Summary

F-18 FDG PET imaging can show increased uptake in the colon due to enterocolitis, not just cancer. This highlights the importance of considering non-neoplastic causes for hypermetabolic colonic lesions.

Area of Science:

  • Nuclear Medicine
  • Gastroenterology
  • Radiology

Background:

  • Positron Emission Tomography (PET) with F-18 FDG is utilized for detecting metabolic activity.
  • Colonic lesions with increased F-18 FDG uptake are often investigated for malignancy.
  • A history of colon carcinoma can influence diagnostic considerations.

Observation:

  • A 60-year-old female patient presented with acute toxigenic enterocolitis.
  • F-18 FDG PET imaging revealed marked, diffuse colonic uptake.
  • Contrast CT confirmed colonic edema and thickening.

Findings:

  • Intensely hypermetabolic colonic lesions were observed on F-18 FDG PET.
  • The observed uptake corresponded to acute enterocolitis, a non-neoplastic condition.

  • Distinguishing inflammatory from neoplastic processes is crucial.

    • Implications:

    • F-18 FDG PET findings in the colon require careful interpretation.
    • Non-neoplastic conditions like enterocolitis should be included in the differential diagnosis.
    • This case underscores the need to consider benign causes of hypermetabolism in the colon.
