Comparison of the Performance of 18F-FDG PET/CT With That of Labeled Leukocyte Scintigraphy in the Follow-up of Malignant Otitis Externa.

Brief Summary

Detailed Description

The management of malignant otitis externa (MEO) is a major issue in patients who are often polypathological and fragile. Appropriate antibiotic therapy must be started quickly after the diagnosis is made and followed for a period of at least 6 weeks. Imaging plays a major role in assessing the extent of the infection and especially healing, after 6 weeks of antibiotic therapy. The persistence of an infection at the end of the treatment, observed in imaging, will allow a change of antibiotic line. This study consists in studying in a population affected by an OEM, the performance of PET/CT with 18F-FDG compared to scintigraphy with labeled leukocytes. The usefulness of the latter in the follow-up of the pathology after antibiotic therapy has already been proven in the literature. The study will aim to show that there is a superiority of 18F-FDG PET/CT compared to labeled leukocyte scintigraphy.
