Ground-glass opacification/opacity (GGO) is a descriptive term referring to an area of increased attenuation in the lung on computed tomography (CT) with preserved bronchial and vascular markings. It is a non-specific sign with a wide etiology including infection, chronic interstitial disease and acute alveolar disease Fibrous dysplasia (FD) is a rare bony disorder in which normal bone is replaced by abnormal fibro-osseous tissue. In general, FD is found in teenagers, and it usually becomes static after adulthood. FD involves the maxilla almost 2 times more often than the mandible Fibrous dysplasia (FD) is a rare bone disorder. Bone affected by this disorder is replaced by abnormal scar-like (fibrous) connective tissue. This abnormal fibrous tissue weakens the bone, making it abnormally fragile and prone to fracture. Pain may occur in the affected areas

Most fibrous dysplasia cases were not obvious boundary but ground glass type. The X-image classification of fibrous dysplasia showed that there were 44 cases of ground glass (61.1%), 10 cases of nodular sclerosis type (13.9%), 3 cases of cystic type (4.2%) and 15 cases of mixed type (20.8%) The primary tool for diagnosis of fibrous dysplasia is an X-ray. While bone appears solid in an X-ray, a fibrous dysplasia lesion has a relative distinct appearance often described as ground glass. The condition may be diagnosed, therefore, even in a person with no symptoms who is getting an X-ray for other reasons Fibrous dysplasia (FD) is a rare condition commonly involving the jaws. While FD has a typical clinical and histological presentation, considerable variation exists. Moreover, overlap of features with other disorders is possible. This study serves to characterize the features of a large case series of FD of the jaws. With IRB approval, the University of Florida Oral Pathology Biopsy Service.

The most common appearance of fibrous dysplasia on CT is an expanded bone showing a ground-glass appearance (Fig. 1A, 1B, 1C, 1D, 1E).The diagnosis of fibrous dysplasia on CT is usually straightforward [2, 3].However, localized fibrous dysplasia on MR imaging often mimics a tumor because fibrous tissue can enhance brilliantly after the injection of contrast material Fibrous dysplasia (FD) is a type of hamartoma, wherein the medullary bone is replaced by immature and poorly calci- fied bone.1,2FD comprises 2-5% of all bone tumors and 7% of benign tumors.3,4FD is caused by an imbalance betwee It is termed as craniofacial fibrous dysplasia, when it involves, though rarely, adjacent craniofacial bones.

Panoramic radiography revealed ground-glass ill-defined lesions in the three different regions of the maxilla and mandible ground glass appearance: A descriptor for a homogenous translucency in radiology, microbiology, or histology, which may obscure cellular detail, equivalent to German milchglassartig Bacteriology The ground glass appearance (GGA) refers to a shadowy pattern seen on culture plates that is midway between the greenish hue of alpha haemolysis, and. A characteristic milky, ground glass aspect was also detectable in the space between the lateral lamina and medial medulla of the ala major (Figure 6). In the lower jaw, a bony hyperplasia with a central osteolytic and a ground glass-like internal structure was found in the angulus area

Fibrous dysplasia is an uncommon bone disorder in which scar-like (fibrous) tissue develops in place of normal bone. This irregular tissue can weaken the affected bone and cause it to deform or fracture. In most cases, fibrous dysplasia occurs at a single site in one bone, but can occur at multiple sites in multiple bones D , Axial computed tomogram shows extensive craniofacial fibrous dysplasia exhibiting the characteristic ground-glass appearance with multiple areas of radiolucency. Note the left maxilla and alveolar ridge with extensive fibrous dysplasia involvement encasing the left maxillary first and second molars ( arrow ; American Dental.

In 1938, Lichtenstein first coined the term fibrous dysplasia (FD).FD is a rare, nonmalignant condition in which normal bone and marrow are replaced by fibrous tissue and randomly distributed woven bone, usually with pain, bony deformity, and pathologic fractures.In general, FD presents in three forms - monostotic, polyostotic, and polyostotic with endocrinopathies, which can be. The radiopaque areas had homogenous ground glass appearance. There is a loss of bone trabeculation, thinning of the cortical boundaries but still intact, and a loss of the lamina dura around the right posterior permanent teeth. The radiographical features of the lesion were indicative of fibrous dysplasia in the maxilla

Fibrous dysplasia/McCune-Albright syndrome (FD/MAS; OMIM#174800) is a rare disorder characterized by skeletal lesions, skin hyperpigmentation, and hyper-functioning endocrinopathies [1, 2].It arises from post-zygotic gain-of-function mutations in the GNAS gene, which encodes the α-subunit of the G s signalling protein [].These mutations disrupt the intrinsic GTPase activity of G s α, leading.

Although endosteal scalloping may be present, a smooth cortical contour is always maintained. Lesions show varying degrees of hazy density with a ground-glass quality, although some may appear almost completely radiolucent or sclerotic Fibrous Dysplasia is a benign, slowly progressive disease of the bone, and usually presents in children and young adolescents. In this disease, normal cancellous bone is replaced by fibrous tissue and immature woven bone.

Fibrous dysplasia of the maxillary sinus might initially become apparent because of facial asymmetry. It can be differentiated from other osseo-odontogenic dysplasias radiographically by its occupancy of the affected sinus and by its diffuse, ground-glass, radiopaque appearance; it can be further confirmed with histologic findings Introduction Fibrous dysplasia is a formative tumor-like Etiology, genetics, and molecular Biology condition that is portrayed by substitution of ordinary The basic reason for FD is not completely caught on. bone by an excessive expansion of fibrous connective Scientists trust that the lesions are created by a mutation tissue intermixed with.

Fibrous dysplasia Radiology Reference Article

Fibrous Dysplasia. Fibrous dysplasia is a benign (noncancerous) bone condition in which abnormal fibrous tissue develops in place of normal bone. As these areas of fibrous tissue grow and expand over time, they can weaken the bone—causing it to fracture or become deformed. Some patients with fibrous dysplasia experience few or no symptoms Radiographically, fibrous dysplasia appears as a well circumscribed lesion in a long bone with a ground glass (ground-glass appearance) or hazy appearance of the matrix. On imaging studies, the lesion is usually well defined, although the rim is not usually sclerotic, and the tissue often has a ground-glass appearance owing to the finely.

Fibrous dysplasia can be picked up on x-rays (ground glass appearance) and contrast CT/ MRI Scans (hypointense expansile bone). 2. The parotid salivary gland is covered by a thick parotid fascia and hence swelling of the parotid gland causes intense pain. The parotid region will also be tense and taut Fibrous dysplasia (FD) is a benign fibro-osseous pathologic condition characterized by the replacement of bone with fibrous tissue [1,2]. The lesion is firstly described by Lichtenstein [3] in 1938. In 1937, Albright et al. [4] described a syndrome characterized by polyostotic fibrous dysplasia that included: areas of pigmentation, skeletal change Fibrous dysplasia clinically presents as a painless swelling of the bone involved. Usually, fibrous dysplasia is a self-limiting disease. Therefore, treatment is only required if there are problems due to local increase in size of the affected bone. Sometimes, an osteosarcoma may arise in fibrous dysplasia. Caused by mutation in the GNAS-1 gene
