2024年12月23日 · Fibrous dysplasia (FD) is a developmental benign medullary fibro-osseous process characterized by the failure to form mature lamellar bone and arrest as woven bone that can be multifocal. It can affect any bone and occur in a monostotic form involving only one bone or a polyostotic form involving multiple bones.

2024年11月16日 · Craniofacial fibrous dysplasia is one of four types of fibrous dysplasia and is characterized, as the name suggests, by involvement of the skull and facial bones. For a general discussion of the underlying pathology, refer to the parent article fibrous dysplasia.

Based on the fibro-osseous ground glass matrix, and CT/MR morphology, the lesion has been presumed to be fibrous Dysplasia. The patient remains stable, and thus no intervention has been planned.

The solitary osseous lesion in the proximal right tibia was favored to represent fibrous cortical dysplasia. The imaging features presented here are typical and may be referred to in the Radiopaedia article.

Fibrous dysplasia is an idiopathic skeletal developmental anomaly, which can affect one or multiple bones. Isolated sphenoid sinus fibrous dysplasia is a relatively uncommon entity. Fibrous dysplasia can have extreme heterogenicity on MR imaging and can be indistinguishable from malignant lesions.

Very prominent changes (bone expansion with intact cortex and ground glass matrix) consistent with known fibrous dysplasia are demonstrated throughout the facial skeleton most pronounced on the left in the frontal bone, bilaterally involving the base of skull, and right maxilla.

Fibrous dysplasia (FD) is a non-neoplastic tumor-like congenital process, manifested as a localized defect in osteoblastic differentiation and maturation, with replacement of normal bone with large fibrous stroma and islands of immature woven bone.

2024年7月27日 · Fibrous dysplasia affecting the cranial bones is a non-malignant disorder characterised by the replacement of normal bone with fibrous tissue and abnormal bone growth. The sclerotic lesions with a "ground glass" appearance on imaging are typical of fibrous dysplasia.

Features suggestive of an eccentric focal fibrous dysplasia at the level of the right frontal sinus ostium and recess. There is no obstruction to the right frontal sinus; however, this may yet develop should the lesion increase in size. The rest of …

Incidental finding of a sphenoid bone and base of skull fibrous dysplasia with the typical ground-glass matrix. The patient presents with a TIA rather than right orbital symptomatology and remains at risk for developing right orbital apex syndrome. The patient is yet to present for the MRI brain and orbital study for further assessment.
