Summary
Two cases of chronic tonsillitis showed high fluorodeoxyglucose-positron emission tomography (FDG-PET) uptake in tonsils. This indicates increased glucose metabolism due to lymphocyte proliferation in active inflammation.
Area of Science:
- Nuclear Medicine
- Pathology
Background:
- Chronic tonsillitis is a common condition.
- Positron emission tomography (PET) with fluorodeoxyglucose (FDG) is used to assess metabolic activity.
Observation:
- Two patients with chronic tonsillitis underwent FDG-PET imaging.
- Symmetrical, increased FDG uptake was observed in both patients' tonsils.
Findings:
- Histopathology of resected tonsils revealed follicular hyperplasia and germinal center lymphocyte proliferation.
- The observed high FDG uptake correlates with increased glucose metabolism in inflamed tonsillar tissue.
Implications:
- FDG-PET may serve as a valuable tool for evaluating the inflammatory activity in chronic tonsillitis.
- Understanding the metabolic profile of tonsillar inflammation can aid in diagnosis and management.
