title: Enchondroma of clivus: appearance on 18F-FDG PET-CT in contrast with MRI.
abstract: A 55-year-old man underwent MRI for right hemifacial pain, which demonstrated a heterogeneously enhancing lesion in right clivus. The lesion was characterized as enchondroma on CT images, which demonstrated increased tracer uptake on PET-CT images. The chondroid matrix showed increased glucose metabolism with no significant enhancement on MRI, suggesting a perfusion-metabolism mismatch.
