Abstract

Whole body imaging is commonly performed in patients with fibrous dysplasia (FD) to screen for additional lesions. However, the frequency of newly-detected lesions in patients presenting with isolated craniofacial FD is unclear. The purpose of this study was to evaluate the frequency of newly-detected FD lesions on whole body imaging in patients with craniofacial FD and no known extracraniofacial lesions or symptoms. This was a retrospective observational cohort study at a tertiary children's hospital in an urban setting. The study population consisted of patients with craniofacial FD who underwent whole body imaging with technetium-99m (Tc-99m) bone scintigraphy or fluorine-18 sodium fluoride positron emission tomography/computed tomography (F-18 NaF PET/CT). Patients with previously identified extracraniofacial lesions, symptoms, or McCune-Albright syndrome were excluded. The primary outcome was the frequency of newly-detected extracraniofacial FD lesions. Fifteen subjects were included (80% female). Mean age at FD diagnosis was 9.6±4.3 years, and mean age at imaging was 10.4±4.2 years. Tc-99m bone scintigraphy was the most common imaging modality (86.7%). Newly-detected extracraniofacial FD lesions were observed in 1 of 15 subjects (6.7%). Two additional subjects (13.3%) had incidental skeletal findings related to recent traumatic injuries. In patients presumed to have isolated craniofacial FD, whole body imaging identified a low frequency of extracraniofacial skeletal lesions. These findings suggest that routine screening may be considered selectively based on clinical history and physical examination. Further investigation is required to develop evidence-based screening guidelines.
