Abstract
Purpose
The aim of our study was to assess the feasibility and usefulness of 2-[18F]-fluoro-2-deoxy-d-glucose positron emission tomography computed tomography ([18F]FDG-PET/CT) in patients affected by retroperitoneal fibrosis.
Materials and methods
We retrospectively evaluated 25 patients studied in two centers: 18 underwent [18F]FDG-PET/CT as initial evaluation, three during follow-up, three during steroid therapy, and one to re-evaluate the disease. Among the group who underwent initial evaluation, ten underwent a second [18F]FDG-PET/CT after steroid therapy.
Results
[18F]FDG-PET/CT was positive in 18 patients and negative in seven. Among the ten patients who underwent a second study after steroid therapy, six showed complete metabolic response, three partial response, and one no significant maximum standardized uptake value (SUVmax) reduction.
Conclusion
Our preliminary results show that [18F]FDG-PET/CT is feasible and suitable for evaluating retroperitoneal fibrosis and is useful in assessing therapy response. Larger studies are desirable to confirm these findings and to determine the appropriate position of [18F]FDG-PET/CT in the diagnostic flow chart for this disease.
