섬유성 골이형성증은 비정상적인 섬유성 골조직으로 대체되며 느리게 진행하는 골병변이다. 섬유성 골이형성증과 부갑상선기능항진증은 흔하게 관찰되는 질환이나 McCune-Albright 증후군 없이 일차성 부갑상선기능항진증에 동반된 섬유성 골 이형성증은 거의 보고된바가 없다. Tc-99m MDP 골스캔이 섬유성 골이형성증의 진단에 유용하다고 알려져 있으나, Tc-99m MIBI 영상은 아직 보고된 바가 없다. 저자들은 McCune-Albright 증후군이 없이 부갑상선기능항진증에 동반된 섬유성 골 이형성증의 Tc-99m MIBI 스캔과 Tc-99m MDP 골스캔의 영상을 비교하였다. Tc-99m MDP 골스캔상 병변 부위에서 증가된 섭취 소견을 보였으며, Tc-99m MIBI 조기영상에서도 동일한 위치에서 섭취증가가 관찰되었다. 2시간 지연 Tc-99m MIBI 영상에서는 Tc-99m MIBI의 섭취가 배출되는 소견을 보였다. 섬유성 골이형성증 병변에서 Tc-99m MIBI 스캔이 유용할 것이라고 생각하며, 섬유성 골이형성증 병변에서 Tc-99m MIBI의 섭취를 증가시키는 인자에 대한 더 많은 연구가 필요할 것으로 생각한다.

Fibrous dysplasia (FD) is a rare, benign bone disease with abnormal bone maturation and fibroblastic proliferation. Optimal treatment of zone 1 craniofacial FD is radical resection and reconstruction. To achieve of structural, aesthetic, and functional goals, we use three-dimensionally designed calvarial bone graft for reconstruction of zygomatic defect after radical resection of FD. The authors used a rapid-prototyping model for simulation surgery for radical resection and immediate reconstruction. Donor site was selected from parietal bone reflect shape, contour, and size of defect. Then radical resection of lesion and immediate reconstruction was performed as planned. Outcomes were assessed using clinical photographs and computed tomography scans. Successful reconstruction after radical resection was achieved by three-dimensional calvarial bone graft without complications. After a 12-month follow-up, sufficient bone thickness and symmetric soft tissue contour was well-maintained. By considering three-dimensional configuration of zygomaticomaxillary complex, the authors achieved satisfactory structural, aesthetic and functional outcomes without complications.

Few cases of florid osseous dysplasia has been described as a condition that characteristically affects the jaws. It usually manifests as multiple radiopaque masses distributed throughout the jaws. Confusion exists about the relationship of florid osseous dysplasia, gigantiform cementoma, chronic sclersing osteomyelitis, sclerosing osteitis or multiple enostosis. Authors experienced a case of florid osseous dysplasia of the jaws in 52-year-old female on the basis of clinical, radiographic and histopathologic findings. The characteristic features are as follows : 1. In clinical examination, there was no clinical sign and symptoms except extracted area. And there was no facial asymmetry. 2. Radiograms show round or lobular dense radiopaque masses surrounded by radiolucent bands in lower molar teeth area bilaterally. And slight increased radiopacities in maxillary molar teeth area bilaterally. There was no expansion or thinning of buccal and lingual cortical bones. There is no displacement or resorption of involved teeth. In right side of mandible, mandibular canal is displaced inferiorly due to mass. 3. Photomicrograms show densely mineralized sclerotic acellular masses with empty lacunae. Pattern is suggestive of cementum, although it could be considered sclerotic bone. In the periphery, lesion consisting of moderately cellular fibrous tissue in which globular calcified products are deposited.

Cemento-ossifying fibroma (COF) is a benign fibro-osseous tumor with fibrous tissue, abnormal cement and bone, or a combination of such elements. These are slow-growing lesions and are more frequent in women. Here, we report the case of a 28-year-old Korean woman. The patient having no underlying disease complained about facial swelling and asymmetry. A firm mass with impacted molars and teeth deviation on the right maxilla was observed. A computed tomography scan was taken and an incisional biopsy was performed. Following this, COF was diagnosed. Complete surgical removal of the lesion was carried out. A post-operative follow-up was conducted and 3 months later the patient reported no discomfort or any sign of recurrence in regards to the lesion. Differential diagnosis with fibrous dysplasia and the COF is important because of the treatment choice. We report a case of COF and offer a review of the literature on this article.

Fibro-osseous lesions are composed of connective tissue and varying amount of mineralized substances, which may be bony or cementum-like structures. It is necessary for oral radiologist to differentiate due to the tendency of these fibro-osseous lesions to show similar histopathologic appearances, while the management of each lesion is different. However we often encounter a little difficulty in judgement because there are some overlaps between concept of each lesions. So recently I suggest, we face a need to review basic concept and classification of several fibro-osseous jaw lesions. In this article, several fibre-osseous lesions, such as fibrous dysplasia, cemento-ossifying fibroma and cemento-osseous dysplasia, will be discussed basing on the review of literature. particular emphasis will be made on the nomenclature revision of WHO's classification in 1992.

Liposclerosing myxofibrous tumor (LSMFT) is a fibro-osseous lesion of the bone with a marked predilection for the intertrochanteric region of the proximal femur. It is characterized by a complex mixture of histological elements including fibrous dysplasia-like features, myxofibrous tissue, lipomatous area, ischemic ossification, xanthoma cells and pseudo-Paget's bone. Though some consider LSMFT as a variant of the fibrous dysplasia, intraosseous lipoma, or other benign osseous lesions, recently LSMFT is emerged as a genuine clinicopathologic entity. We experienced a 48-year female patient with typical histologic and radiologic findings of LSMFT. It was located at the intertrochanteric area of the femur. Radiologically, the lesion was radiolucent and ground-glass appearance with sclerotic rim in the plain film and magnetic resonance imaging. Histologically, myxofibrous tissue, lipomatous area and fibrous dysplasia-like features were predominant findings.

From Aug. 1975 to Aug. 1981,3 patients with primary benign rib tumors have been treated at the department of thoracic surgery, Paik Hospital, Seoul, Korea. Of these, one was aneurysmal bone cyst and two were fibrous dysplasia. Complete excision of the benign tumor including rib resection was performed in all patients and resulted in long term cure.

Carotid web is a disease that is rarely found in patients with ischemic stroke, whereas it is more frequently observed in cryptogenic stroke patients. Fibromuscular dysplasia is known as the cause of carotid web, and it has been reported that carotid web causes blood flow disturbance, resulting in both thrombus and embolic stroke. Carotid web is confused with carotid dissection because fibromuscular dysplasia causes relatively rigid fibrous structures to grow into the lumen of the carotid artery and this creates a double lumen that is seen on duplex sonography. In addition, carotid web is web-shaped and may be confused with other carotid artery diseases such as ulcerative plaque. However, carotid web tends to be thicker at the beginning and thinner at the end, and it also has no flutter. Therefore, this study reports on four cases of carotid web with the overall description of the carotid web and the characteristic findings of duplex sonography in patients with carotid web.
