Monostotic fibrous dysplasia of the vertebra is a rare entity. A case of a 53-year-old lady who presented with an 8 months history of pain in the thoracic spine region with paraparesis is discussed. She had a history of papillary thyroid carcinoma and had undergone total thyroidectomy one year prior to her current problem. Magnetic resonance imaging revealed isolated osteolytic lesion over the posterior element of the T12 vertebra with narrowing of the spinal canal causing compression of the cord. The diagnosis of fibrous dysplasia was made histologically. Fibrous dysplasia rarely occurs in axial bones compared with peripheral bones. This case illustrates that osteolytic lesion of the vertebrae should be evaluated with detailed radiological and histopathological examination before an empirical diagnosis of spinal metastasis is made in an adult with a background history of primary malignancy well-known to spread to the bone.

Fibrous dysplasia is a developmental disease of the bone, characterized by the replacement of normal spongiosa and filling of the medullary cavity of affected bones by an abnormal fibrous tissue. Fibrous dysplasia arising in the paranasal sinus is rare and usually secondary to the extension of diseases from adjacent bones, and is rarely limited to the sinuses. Two patterns are predominant: he monostotic type, in which only one bone is affected; and the polyostotic type, in which multiple bones are affected. Recently, we experienced a case of monostotic fibrous dysplasia which was confined to the maxillary sinus and approached by the Caldwell-Luc method. Hence, we report a case of fibrous dysplasia of the maxillary sinus with a review of literature.

Fibrous dysplasia of bone is a condition affecting one or more bones, usually not disabling, of slow progress, and showing a tendency to become arrested. The etiology of fibrous dysplaia is unknown but it is now believed to be a developmental error in which primitive fibrous tissue proliferates within the bony medulIa and encroaches upon the cortex from within, often producing expansion. The process may be localized to a small segment or may involve almost the entire shaft of the bone, and it may be monostotic, monomelic or polyostotic. In the latter form some patients exhibit a remarkable combination of skin pigmentation and endocrine disturbances. This paper reports the one case of polyostic and three cases of monostotic fibrous dysplasia. The disgnosis was made by clinical, radiological and histological findings.

Fibrous dysplasia is a common benign skeletal lesion that may involve a single bone or multiple bones. Although fibrous dysplasia can affect any bone, monostotic fibrous dysplasia of the long bone typically occurs in the diaphysis or metaphysis. We report a very rare case of monostotic fibrous dysplasia involving the epiphysis of the distal femur in a young man.

Fibrous dysplasia is a slowly progressive, benign disorder characterized by fibrous tissue replacement of skeleton and may affect solitary or multiple bones. Monostotic fibrous dysplasia mainly occurrs in the rib, femur and tibia, however, rarely in the hand. We report a case of monostotic fibrous dysplasia confined to the 2nd metacarpal bone with findings of plain radiographs and MR imaging.

Fibrous dysplasia (FD) is an uncommon skeletal disorder in which normal bone is replaced by abnormal fibro-osseous tissue. Mainly, FD is found in children, and by adulthood it usually becomes quiescent. Our case showed FD of more than 14-year duration in the left maxilla. Our evaluation was that growth ceased in adulthood and had achieved the static stage. Because FD cases in elderly patients are rarely reported, we hereby present a monostotic FD case in a 65-year-old female. We presented sequential radiographic images and scintigraphic images of this case, and combined them with a literature review that emphasized the progression of the disease.

Fibrous dysplasia is a rare fibro-osseous lesion characterized by replacing the skeletal structure. Its main feature is the involvement of one or several bones of the skeletal and extra-skeletal systems. Fibrous dysplasia arising in the paranasal sinus is rare, especially in the ethmoid and sphenoid sinuses. Only one case of fibrous dysplasia originating in the sphenoid sinus have been reported in the regional and international literature. Recently we experienced a case of monostotic fibrous dysplasia which derived from the sphenoid sinus in a 33-year-old female. So the case will be discussed with literature review.

OBJECTIVE: To study the etiopathogenesis, clinical features, diagnosis and treatments of monostotic fibrous dysplasia of the sphenoid sinus. METHOD: Two cases of monostotic fibrous dysplasia of the sphenoid sinus without any symptoms was reported with relevant literature review. RESULT: No aggravation was found after 6 months-follow-up. CONCLUSION The cranial fibrous dysplasia has low incidence rate with non-specific symptoms and high rate of misdiagnosis. The monostotic fibrous dysplasia of the sphenoid sinus without any symptom is rarely seen clinically. Imagiological examination, for example, CT and MRI, is valuable for the diagnosis of this disease. The histopathological evidence is absolutely necessary to make definite diagnosis. The conservative treatment may be chosen for the asymptomatic cases. Nasal Endoscopic surgery can not only remove the diseased region but also make diagnosis. The long-term follow-up should be carried out in all of these patients.

Fibrous dysplasis is a condition characterized by the metastatic replacement of the medullary component of predominantly long bone with fibrous tissues. This change is responsible for the characteristic features, including bony abnormalities, pathologic fractures and pain. The monostotic form of the fibrous dysplasia occurs more freguent than the polyostotic form. The monostotic fibrous dysplasia does not exhibit the laboratory abnormality, extra-skeletal manifestation or the endocrinopathies associated writh polyostotic disease. Monostotic fibrous dysplasia occurs most frequently in the metaphysis of long bones and the ribs. Only the seven previous cases of vertebral involvement (three cervical, one thoracic, three lumbar spine) in monostotic fibrous dysplsia have been reported. Authors experienced a case of monosotic fibrous dysplasia of the seventh cervical vertebrate, so we report a case with the review of the seven previous reported cases of the monosotic fibrous dysplasia of the spine.

Fibrous dysplasia is a benign fibro-osseous lesion originally described by Lichtenstein in 1938. Currently, three general subtypes of disease are recognized: monostotic, polyostotic, and McCune-Albright syndrome. Fibrous dysplasia is not rare, with the incidence report being about 5% to 7%. Common sites of fibrous dysplasia are the skeletal system including long bones, ribs, craniofacial bones, and the pelvis. However, fibrous dysplasia is rare in the nasal cavity, especially involving the turbinate. In the review of literature over the past 50 years, we were able to discover only 4 cases in which the fibrous dysplasia involved inferior turbinate, with all of them being the polyostotic form found around the sinuses. There were only 4 cases in which monostotic fibrous dysplasia involved the middle turbinate, but none the inferior turbinate. We present this case, with a review of the relevant literature, as the first report on monostotic fibrous dysplasia of the inferior turbinate.
