All patients with known or suspected McCune–Albright syndrome should undergo a screening evaluation for fibrous dysplasia. [18] Nuclear medicine tests such as technetium-99 scintigraphy are the most sensitive way to detect fibrous dysplasia lesions. [19] CT scan of the skull is the most useful test to evaluate craniofacial fibrous dysplasia ...
Fibrous dysplasia is a mosaic disease resulting from post-zygotic activating mutations of the GNAS locus at 20q13.2-q13.3, which codes for the α subunit of the G s G protein-coupled receptor. [13] In bone, constitutive G s α signaling results in impaired differentiation and proliferation of bone marrow stromal cells . [ 14 ]
Fibrous dysplasia is a rare congenital disease of the bone that often affects the cranial facial structures, Dr. Netanel Ben-Shalom, a nuerosurgeon, at Northwell Lenox Hill Hospital, tells TODAY ...
In neurofibromatosis type 1, the spots tend to be described as ovoid, with smooth borders. In other disorders, the spots can be less ovoid, with jagged borders. In neurofibromatosis type 1, the spots tend to resemble the "coast of California" rather than the "coast of Maine", meaning the edges are smoother and more linear. [2]
Polyostotic fibrous dysplasia is a form of fibrous dysplasia affecting more than one bone. [2] Fibrous dysplasia is a disorder where bone is replaced by fibrous tissue, leading to weak bones, uneven growth, and deformity. [3] McCune–Albright syndrome includes polyostotic fibrous dysplasia as part of its presentation. [4]
Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
It comprises a majority of the cases of fibrous dysplasia (approximately 70–80%). [2] It is a rare bone disease characterized by the replacement of normal elements of the bone by fibrous connective tissue, [3] which can cause very painful swellings and bone deformities, and make bone abnormally fragile and prone to fracture.
