Eosinophilic Fasciitis Illustrated by 18F-FDG PET/CT

Abstract

Eosinophilic fasciitis is a rare sclerodermiform disease characterized by upper and lower limb edema. We present the case of a 71-year-old woman currently hospitalized for painful lower limb edema. Laboratory tests reveal moderate eosinophilia (0.8 g/L) and an inflammatory syndrome. Abdominopelvic ultrasound reveals no abnormalities. In light of the unexplained inflammatory syndrome, a 18F-FDG PET/CT scan currently shows intense hypermetabolism of the fasciae in the lower and upper limbs. Following an MRI, a biopsy is performed, and the anatomopathology currently confirms eosinophilic fasciitis.
