Introduction:
Fibrous dysplasia is a benign, idiopathic, fibro-osseous disease.
Clinical Case:
A 17-year-old girl had presented with left proptosis for the previous two years, associated to homolateral hemicranial pain. Clinical examination was normal except for non-reducible axile exophthalmia. Computed tomography and magnetic resonance imaging of the head revealed an extensive cystic tumor of the left fronto-ethmoido-sphenoidal region, with compression of the left frontal lobe and medial orbital wall. The radiological appearance suggested a mucocele but histological examination, after surgery, proved a fibrous dysplasia.
Discussion:
Fibrous dysplasia with fronto-sphenoido-ethmoidal localization may be misdiagnosed as mucocele. Histology proves the diagnosis.

Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
Sutures 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...
Structural 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...
Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
