Summary
Fibrous dysplasia (FD) imaging on CT/MRI varies. This case study shows monostotic FD in a boy’s maxilla evolving from an "onion peel" to "egg-shell" then "ground-glass" appearance over five years.
Area of Science:
- Radiology
- Oncology
- Pathology
Background:
- Fibrous dysplasia (FD) is a bone disorder where normal bone is replaced by fibrous tissue.
- Imaging findings for FD on computed tomography (CT) and magnetic resonance imaging (MRI) are variable.
- Previous literature suggests radiographic changes may indicate FD progression.
Observation:
- A 12-year-old boy presented with monostotic FD in the right maxilla.
- Initial CT scans revealed a lamellar, "onion peel"-like structure.
- Over five years, the lesion evolved to an "egg-shell lesion" and finally a "ground-glass lesion" appearance.
Findings:
- This case illustrates the dynamic evolution of monostotic fibrous dysplasia imaging characteristics.
- The observed changes correlate with potential progression of the condition.
- The transition from "onion peel" to "ground-glass" signifies distinct stages of FD development.
Implications:
- Understanding these imaging transitions can aid in diagnosing and monitoring FD.
- This case highlights the importance of serial imaging in assessing FD progression.
- Further research into the correlation between imaging features and clinical outcomes is warranted.
