Summary

Bone infarcts can show increased F-18 fluorodeoxyglucose (FDG) uptake on PET scans, mimicking bone metastases. This case highlights the importance of considering benign causes like bone infarct in diagnostic imaging.

Area of Science:

  • Nuclear Medicine
  • Oncology Imaging
  • Pathology

Background:

  • Positron emission tomography (PET) with F-18 fluorodeoxyglucose (FDG) is crucial for detecting metastatic disease.
  • Differentiating benign conditions from malignant lesions is essential in cancer follow-up.

Observation:

  • A patient with a history of breast cancer presented with rib pain and suspicious findings on bone scan.
  • FDG PET imaging revealed increased uptake in the ribs, initially concerning for metastases.

Findings:

  • Histopathological examination of the resected rib segment confirmed bone infarct, not metastatic cancer.
  • The increased FDG uptake was attributed to an inflammatory process within the bone infarct.

Implications:

  • Bone infarcts can exhibit FDG avidity, potentially leading to false-positive findings for metastasis on PET scans.
  • This underscores the need for careful interpretation of FDG PET findings in the context of clinical and pathological data.
