1/16. A giant intracranial mucocele associated with an orbitoethmoidal osteoma. Case report.The authors present a rare case of a giant intracranial mucocele associated with an orbitoethmoidal osteoma in a patient suffering from a generalized convulsive disorder. The broad pedicle of the osteoma had penetrated the cribriform plate and extended intracranially to form a nodular mass in the olfactory groove. The intracranial portion of the osteoma was surrounded by a mucocele. Both the cyst wall and multilayered intracystic septations of the mucocele were indented by layers of the osteoma. Although the extracranial portion adhered to the mucosa of the ethmoidal sinus, there were no signs of sinus obstruction. No direct communication other than the osteoma was identified between the mucocele and the ethmoidal mucosa. The large cerebral defect, which the mucocele occupied, communicated directly with the lateral ventricle without any intervening membranous structures. A frontal craniotomy is recommended for exposure of the lesion and plastic repair of the dural defect.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/16. Giant ethmoid osteoma with orbital extension presenting with epiphora.Paranasal sinus osteoma is a slow-growing, benign, encapsulated bony tumour that may be commonly asymptomatic, being detected incidentally in 1% of plain sinus radiographs or in 3% sinus computerized tomographic scans. In a patient presenting with epiphora and nasal obstruction, computed tomography disclosed a giant osteoma of the ethmoid. In this article, one patient having giant ethmoidal osteoma with orbital extension is described, and epidemiology, diagnosis, treatment, and pathological findings in paranasal sinus osteoma are reviewed.- - - - - - - - - - ranking = 0.4keywords = giant (Clic here for more details about this article) |
3/16. Giant osteoma of the frontoethmoidal sinus associated with two cerebral abscesses.A 36-year-old woman presented with severe frontal headache, fever, left palpebral swelling, and proptosis. Radiographic studies showed a giant frontoethmoidal osteoma, that extended intracranially into the frontal lobe and was associated with two abscesses, one within the lesion and the other in the right frontal lobe. The tumour was excised and the abscesses drained.The patient made a full recovery.- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
4/16. Multiple and giant mandibular osteomas in a Gardner's syndrome. Case report.Though rare, Gardner's syndrome is a systemic disease with frequent jawbones involvement. Dento-maxillo-facial lesions both in early and in advanced stages should be known by dentists and other specialists. In fact, these lesions should be sought in patients with intestinal polyposis, while they could be the first sign of Gardner's syndrome not yet diagnosed.- - - - - - - - - - ranking = 0.8keywords = giant (Clic here for more details about this article) |

6/16. Central giant cell granuloma and fibrous dysplasia occurring in the same jaw.Fibrous dysplasia (FD) is a developmental tumor like condition that is characterized by replacement of normal bone by an excessive proliferation of cellular fibrous connective tissue intermixed with irregular bony trabeculae. Central giant cell granuloma (CGCG) is described as a benign lesion affecting the mandible and maxilla that consists of a massive fibrohistiocytic proliferation with numerous heavily hemosiderin-laden multinucleate-giant cells. A 20 year old woman present at the Department of oral medicine, dentistry School, Tehran University of Medical Sciences with a slowly growing non painful swelling of the right mandible for one year. Our differential diagnosis was osteoma, osteoid osteoma and Fd. The histological feature reveal Central giant cell granuloma fibrous dysplasia. Central giant cell granuloma and fibrous dysplasia occurring in the same jaw is rarely reported in the literatures.- - - - - - - - - - ranking = 1.6keywords = giant (Clic here for more details about this article) |
7/16. Ossifying fibroma of the maxillary sinus: a case report.A case of ossifying fibroma of the maxillary sinus that occurred in a 45-year-old white female is reported. The lesion's radiographic, histologic and clinical behavior are examined. The clinical and radiographic features of ossifying fibroma distinguish it from monostatic fibrous dysplasia despite histologic similarities. The uncommon location of this ossifying fibroma in the maxillary sinus accounts for its large size, aggressive behavior and widespread osseous destruction. The prognosis is excellent after complete enucleation of the ossifying fibroma has been achieved. The benign fibro-osseous lesions of the jaws share similarities in radiographic and clinical appearance, histogenesis and histopathology, and consequently, pose difficulty in classification and treatment. Common histologic features of these lesions include an active proliferation of fibroblats, young and mature collagenous connective tissue, focal areas of mineralization which may resemble small cemeticles and/or irregular bone trabeculae, and multinucleated giant cells. Differential diagnosis of benign fibro-osseous lesions can therefore be made if clinical behavior, radiographic features, and hematologic changes are correlated with the histologic picture. Representatives of this group include true fibrous dysplasia, ossifying fibroma (both central and peripheral types), osteoid osteoma, osteoblastoma, cementifying fibroma, florid osseous dysplasia, proliferative periostitis of Garre, focal sclerosing osteomyelitis and osteitis deformans (Paget's disease).- - - - - - - - - - ranking = 0.2keywords = giant (Clic here for more details about this article) |
8/16. Giant osteoma of the cranial vault with acromegaly and hydrocephalus. A case report.A case of acromegaly associated to a giant osteoma of the cranial vault and hydrocephalus in a young woman is reported. It can be suggested that acromegaly favoured the marked growth of the osteoma. hydrocephalus resulted consequent to both the compression of the superior longitudinal sinus by the tumor and alteration of the CSF resorption. The rarity of giant osteomas of the cranial vault associated with intracranial hypertension is pointed out.- - - - - - - - - - ranking = 0.4keywords = giant (Clic here for more details about this article) |

10/16. Resection of a giant ossifying fibroma through an intraoral approach in a 9-year-old child: immediate reconstruction and 6-year cephalometric follow-up.An unusual opportunity was afforded to study the growth and development of the facial structures of a 9-year-old child who underwent major mandibular reconstruction. The longitudinal studies confirmed the present concepts of the factors responsible for mandibular growth as well as their repercussions on other facial structures. An intraoral subperiosteal resection of a major portion of the right hemimandible sparing the upper part of the mandibular ramus was required to eradicate a large ossifying fibroma. An iliac bone graft consisting of the outer table of cortical bone and cancellous bone was placed within the mucoperiosteal sac to repair the defect. It also was used to control the ramus remnant. The patient was followed for 6 years. The growth of the reconstructed mandible was in effect nearly symmetrical with the unaffected contralateral portion of the mandible, resulting in minimal facial asymmetry. The mucoperiosteum provided a vascular bed for the bone graft and the buccal sulcus was preserved, thus providing a retentive ridge and sulcus for a denture without the need to perform a skin or mucosal graft inlay procedure. The symmetrical growth of the mandible is attributed to the growth of the ramus by remodeling, resorption, deposition, and relocation and by the muscle-bone interface (the functional matrix).- - - - - - - - - - ranking = 0.8keywords = giant (Clic here for more details about this article) |
