1/47. Giant-cell tumor of the skull base.giant cell tumors are uncommon primary bone tumors. They primarily occur in the long bones. giant cell tumors are extremely rare in the skull and head and neck. When it does occur, the maxilla and mandible are the common sites to be involved. We described two cases of giant cell tumor in the temporal bone. In the noncontrast enhanced CT, the lesion presents as a soft tissue density mass with expansion of the bone. The bony cortex is usually intact. The adjacent soft tissues and cerebral parenchyma show no infiltration or edema. The post contrast scan reveals homogenous enhancement of the mass.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/47. Aggressive basal cell carcinoma of the temporal region in a patient with Gorlin-Goltz syndrome.Gorlin-Goltz syndrome is an autosomal dominant disorder with variable penetration characterized primarily by five major findings: multiple basal cell carcinomas presenting at a young age, pits on the palms and soles, skeletal abnormalities, jaw cysts, and ectopic calcification of the falx cerebri and other structures. When the basal cell carcinomas are located in the head and neck there is a high risk of invasion of deep structures if early and radical treatment is not performed. The authors present a 59-year-old man affected by basal cell carcinoma in the context of Gorlin-Goltz syndrome. Although patients with this syndrome can present aggressive basal cell carcinomas, it is unusual to find them involving the craniofacial bones. In this patient the basal cell carcinoma involved the middle ear, the intrapetrous aspect of the facial nerve, and the dura mater. The reconstruction of a wide three-dimensional defect, in which the brain was exposed, was achieved with local flaps and a free musculocutaneous rectus abdominis flap. Factors affecting reconstruction in the lateral cranial base are discussed.- - - - - - - - - - ranking = 0.073773197196111keywords = jaw (Clic here for more details about this article) |
3/47. Desmoplastic fibroma of the temporal bone.An unusual case of a desmoplastic fibroma of the temporal bone is presented. Although classified benign, this intraosseous lesion exhibits local aggressiveness and has a high potential for recurrence. This rare condition occurs predominantly in the mandible and in the long bones and is seldom seen in the calvarium. Here we add another case to the previously described eight in the skull and this is the fourth such case reported in the temporal bone. The clinical features, radiology, histopathology and the therapeutic considerations of this lesion in a 72-year-old female are discussed. In addition, a literature review of all the cases affecting the skull bones is presented.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/47. The radiological features of craniofacial neurofibromatosis.Three cases of neurofibromatosis are reported showing a wide spectrum of roentgen abnormalities affecting the skull and facial bones. One case had macrocrania and multiple calvarial defects; enlargement of the sella turcica and middle cranial fossa was also present. All the three cases had orbital changes either in the form of enlargement, reduced anteroposterior width or loss of bony outlines with an appearance of emptiness. The other two cases showed predominantly facial involvement with hypoplasia of the mandibular body and ramus, abnormal coronoid process, zygomatic arch, hypoplastic maxilla, cystic mandible with abnormal dentition and absence of the osseous external auditory meatus. Intra-orbital calcification was present in one case. The radiological projections required to evaluate such cases are discussed. The 20 degrees occipito-mental view has been found extremely useful and is recommended.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
5/47. Intraosseous hemangioma of the zygoma: CT and MR findings.Intraosseous hemangiomas are uncommon, constituting less than 1% of all osseous tumors. The most frequent sites are the calvaria and the vertebral column. Involvement of the facial bones is rare, and occurs most commonly in the maxilla, mandible, and nasal bones. Only 20 cases of zygomatic involvement have been reported in the English-language literature. We report a case of an intraosseous hemangioma of the zygoma documented by CT and MR studies.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/47. Osteoid osteoma of the eminence of the temporomandibular joint.We describe an osteoid osteoma in the articular eminence of the left temporomandibular joint of a 24-year-old woman. This is an uncommon tumour of the jaws, and has not previously been reported in this location. The mass was removed, she made a good recovery, and there are not signs of recurrence four years later.- - - - - - - - - - ranking = 0.073773197196111keywords = jaw (Clic here for more details about this article) |
7/47. Cavernomas of the skull: review of the literature 1975-2000.We describe four patients with intraosseous cavernous hemangiomas of the skull which were localized supraorbitally, parietally (two cases), and occipitally. The diameter ranged from 15 mm to 25 mm. They presented with slowly growing mass, tender to pressure, with spontaneous pain, and with freely mobile skin above the cavernoma sites. magnetic resonance imaging (hyperintensity on T2 and isointensity with brain on T1) and CT (osteolytic lesion with erosion of the tabula externa) confirmed the plain skull films showing the honeycomb or sunburst appearance pattern. Resections and postoperative course were uneventful. In three of these cases there was coexistence with tumors (meningeoma, malignant lymphoma, and malignant melanoma); none of these constellations has been described before. Generally, cavernous hemangiomas of the skull are rare. There is one extensive review published by Barnes in 1984 regarding a period of 136 years with 123 intraosseous hemangiomas of the skull and 74 of the jaws. Unfortunately, the histological confirmation is not completely clear and some capillary hemangiomas are included. In a review of the literature since 1975, we found 103 histologically proven intraosseous cavernous hemangiomas of the skull (with our four cases included) and 22 of the jaws, which are shown in an overview with respect to their localization. The most frequent site was frontal, followed by temporal.- - - - - - - - - - ranking = 0.14754639439222keywords = jaw (Clic here for more details about this article) |
8/47. Usefulness of vascular examinations in diagnosis and treatment of the face-skull neoplasms.Arteriography of external carotid artery and sporadically orbitophlebography were performed in 52 patients of both sexes, aged 10-74 years. Indications for arteriography and orbitography stemmed from cases in which routine clinical-radiological examinations failed to determine the extent of neoplastic changes. The technique of transdermic puncture of the common carotid artery of the supraorbital vein was applied in the studies. Uropolin 75% was used as control material. The studies confirmed usefulness of arteriography both in the diagnosis and surgical treatment of neoplasms of the jaws as well as the face facilitating the determination of topography of the tumor and the direction of growth.- - - - - - - - - - ranking = 0.073773197196111keywords = jaw (Clic here for more details about this article) |
9/47. Desmoplastic fibroma of the cranium: case report and review of the literature.OBJECTIVE AND IMPORTANCE: Desmoplastic fibroma is a benign bone tumor that can be locally aggressive. It usually occurs in the long bones and mandible. We report on a patient with a desmoplastic fibroma arising in the temporal bone and review previously published cases of desmoplastic fibroma originating within the cranium. CLINICAL PRESENTATION: A 43-year-old woman presented with a 12-year history of progressively worsening head asymmetry. magnetic resonance imaging and computed tomography demonstrated a mass originating from the bone and involving the adjacent soft tissues. INTERVENTION: A temporal parietal craniectomy was performed with excision of a large tumor involving the bone. An acrylic cranioplasty was used to replace the bone. Pathological examination of the lesion identified desmoplastic fibroma of the cranium. After surgery, the patient's cranial asymmetry was corrected. CONCLUSION: Desmoplastic fibroma of the cranium is rare. Surgical resection is the treatment of choice.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
10/47. Malignant haemangio endothelioma (angiosarcoma) concomitant presentation in the mandible and occiput--a case report.A case of angiosarcoma presenting simultaneously in the mandible and occiput is presented. The mandibular swelling was preceded by toothache for which the patient had tooth extraction, after which the rate of growth increased tremendously. It was not possible to determine without doubt which lesion presented first. The need to evaluate and investigate all cases of jaw swelling that require tooth extraction is emphasised. Angiosarcoma being a haemorrhagic lesion could be complicated life threatening haemorrhage, if a tooth related to it is extracted, as was experienced on incisional biopsy of this lesion. The procedure was accompanied by torrential bleeding which was only controlled after external carotid artery ligation. This, to our knowledge, is the first reported case of angiosarcoma occurring simultaneously in the mandible and occipital bones.- - - - - - - - - - ranking = 6.0737731971961keywords = mandible, jaw (Clic here for more details about this article) |
