Insights
A 5-year-old boy with craniofacial fibrous dysplasia (FD) showed swelling. Imaging, including CT and MRI, helped diagnose the condition, distinguishing it from other possibilities like mucocele.
Area of Science:
- Radiology
- Pediatric Imaging
- Craniofacial Abnormalities
Background:
- Fibrous dysplasia (FD) is a benign bone disorder.
- Craniofacial FD can present with cosmetic and functional issues.
- Early diagnosis is crucial for appropriate management.
Observation:
- A 5-year-old boy presented with progressive right frontal swelling.
- Imaging revealed a ground-glass pattern consistent with craniofacial fibrous dysplasia.
- Differential diagnosis included inspissated mucocele.
Findings:
- Computed tomography (CT) showed hypo dense fibrous tissue.
- Magnetic resonance imaging (MRI) with contrast enhancement was key for diagnosis.
- Characteristic imaging features aided in differentiating FD from mucocele.
Implications:
- Accurate diagnosis of craniofacial FD is essential for treatment planning.
- Advanced imaging techniques like MRI are vital for characterizing craniofacial lesions.
- Understanding imaging nuances aids in distinguishing FD from other conditions like mucocele.
Abstract:
The case of a 5-year-old boy with ground-glass pattern craniofacial fibrous dysplasia (FD) presenting with progressive swelling in the right frontal region is reported. The imaging findings with computed tomography and magnetic resonance imaging (MRI) findings are presented. The differential diagnosis with inspissated mucocele is discussed as well. Fibrous tissue could be hypo dense on CT. Post-contrast enhancement of the lesion on MRI is the key for diagnosis.

01:03Structural Joints: Fibrous Joints
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
