1/74. giant cell tumors of the jugular foramen.PURPOSE: To review the diagnosis and treatment of giant cell tumors of the jugular foramen. MATERIALS AND methods: A typical case is reported. Symptoms, signs, and diagnostic studies are reviewed. Photomicrographs and angiographic studies showing the differences between these and glomus jugulare tumors are provided. A coherent approach to their management is presented. RESULTS: These hypervascular, traditionally radioresistant tumors may cause pulsatile tinnitus, conductive hearing loss, and lower cranial nerve paresis. Angiographic studies showed a hypervascular lesion supplied by numerous small branches of the external carotid artery, making embolization difficult. Complete resection was achieved by an infratemporal fossa approach with preoperative embolization. CONCLUSION: giant cell tumors of the temporal bone may mimic glomus jugulare tumors with respect to anatomic location, cranial nerve deficits, and vascularity.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
2/74. 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 = giant (Clic here for more details about this article) |
3/74. Long-term survival of a patient with a giant-cell tumor of the sphenoid body: a case report.Giant-cell tumors (osteoclastomas) of the sphenoid body are rare, histologically benign lesions that can grow in different directions within the bony structures of the skull base. To date, the precise role of the different surgical strategies (radical versus partial resection; biopsy) and of supplementary postoperative radiotherapy remains undefined due to the short follow-up of the majority of the reported cases. We present a patient who is alive without symptoms or signs of recurrence 44 years after a macroscopically radical excision of the neoplasm followed by radiotherapy.- - - - - - - - - - ranking = 4keywords = giant (Clic here for more details about this article) |
4/74. Synchronous multicentric giant cell tumour: a case report with review of literature.Synchronous multicentric giant cell tumour (MGCT) is a rare occurrence. We report a young woman who presented with a synchronous skull and lower shaft femur giant cell tumour, who had previously received radiotherapy to both the sites, it being deemed inoperable at initial assessment.- - - - - - - - - - ranking = 6keywords = giant (Clic here for more details about this article) |
5/74. Giant-cell tumour involving the cranial vault: imaging and treatment.A giant-cell tumour involving the cranial vault was diagnosed in a 37-year-old man who presented with a large swelling at the vertex. The role of imaging in the diagnosis and treatment of this tumour is described. On CT and MRI the appearances were nonspecific and the diagnosis was established by histological examination after removal of the tumour. A preoperative angiogram showed a tumour blush and before surgery, embolisation was performed via the percutaneous and transarterial routes.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
6/74. Solitary plasmacytoma of the calvarium.A solitary plasmacytoma of the calvarium was removed radically without postoperative radiotherapy. A 69-year-old female patient was operated for a giant solitary plasmacytoma in the frontal region and the follow-up over 10 years revealed no recurrence. The authors discuss that solitary plasmacytoma of the calvarium may have a good prognosis if radically removed and the radiotherapy may not be necessary.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
7/74. Giant cell tumour of the temporal bone: case report and review of the literature.This paper presents an expansile lesion of the temporal bone, in a 14-year-old boy, that was initially diagnosed as intra-osseous meningioma from CT appearance. At histopathology a final diagnosis of giant cell tumour was made. A brief review of the literature is presented for this rare case.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
8/74. Malignant giant-cell tumor of the parietal bone: case report and review of the literature.OBJECTIVE AND IMPORTANCE: Giant-cell tumors (GCTs) are primary bone tumors that involve long bones in 75 to 90% of patients. They seldom develop in the cranium and are very rare in patients older than 60 years of age. A GCT rarely occurs with Paget's disease; when it does, however, it is most commonly associated with the polyostotic form and tends to involve the craniofacial bones. Pagetic GCTs are less aggressive than GCTs that are not associated with Paget's disease. CLINICAL PRESENTATION: We report the case of an 81-year-old woman with a painless left parietal mass and asymptomatic monostotic parietal Paget's disease. INTERVENTION: Surgical resection was performed, and histological examination of the lesion demonstrated Paget's disease with a malignant GCT. An incidental, low-grade, small-cell lymphocytic lymphoma also was noted. The patient experienced local recurrence of the malignant GCT and eventually died after developing pulmonary metastases of the malignant GCT. CONCLUSION: This case is the first reported example of a patient with a malignant GCT of the cranium associated with monostotic Paget's disease. It provides evidence that not all pagetic GCTs in the cranium are benign, as has been reported.- - - - - - - - - - ranking = 4keywords = giant (Clic here for more details about this article) |
9/74. Radiosensitive giant cell tumour of the sphenoid bone.Giant cell tumours rarely occur in the cranial region. We encountered a radiosensitive giant cell tumour of the sphenoid in a 12-year-old girl. After a two-stage operation, the residual tumour regrew rapidly. The adjuvant radiotherapy subsequent to additional surgery has suppressed the growth of the residual tumour for 5 years.- - - - - - - - - - ranking = 5keywords = giant (Clic here for more details about this article) |
10/74. Extensive cerebral invasion of a basal cell carcinoma of the scalp.Basal cell carcinomas (BCC) are the most common cutaneous malignant neoplasms affecting fair-skinned human beings. They may progressively enlarge and spread by peripheral extension. Intracranial invasion is very rare. A case of a giant BCC of the scalp invading directly into the left hemisphere through the frontal and parietal lobe and meninges is presented. brain invasion along Virchow-Robin's spaces is demonstrated histopathologically. A review of literature failed to disclose a previous report of similar extensive and fatal cerebral invasion from a basal cell carcinoma of the scalp. copyright Harcourt Publishers Limited.- - - - - - - - - - ranking = 1keywords = giant (Clic here for more details about this article) |
