1/5. Cochleo-vestibular manifestations of jugular foramen pathologies.patients presenting pathologies of the jugular foramen are presented, for whom the main symptoms are of cochleo-vestibular nature. A classification of the various pathologies is attempted, the anatomy reviewed and hypotheses capable of producing the symptom elaborated.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/5. Extracranial tumor vascularity: determination by dynamic CT scanning. Part II: The unit approach.Twenty-eight patients had combined conventional drip infusion CT scans. The information about the anatomic location of the lesion, its configuration, its cross-sectional appearance, its vascularity (as determined by dynamic signature curves), and its clinical presentation were considered as a single overall unit. This diagnostic approach allowed a diagnosis to be made on virtually all of these enhancing lesions without resorting to either a digital venous imaging study or angiographic procedure. In 17 of these cases, such an invasive second procedure was performed either to confirm the CT impression as part of this study or as part of a therapeutic embolization procedure.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/5. Angioma of the jugular foramen. Case report.We describe a patient with a neoplasm closely mimicking a glumous jugulare tumour with regard to both clinical and radiological presentation. The tumour was removed by the transmastoid route. Only after histological examination of the excised neoplasm could the diagnosis of angioma be made. No other case of this nature has been found in the literature.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/5. MRI features in a malignant glomus jugulare tumour.magnetic resonance imaging (MRI) features in a case of malignant glomus jugulare tumour are reported. Chemodectomas are benign in 95 per cent of cases and malignant in five per cent. Only one case report of CT findings in this unusual CP angle tumour with pulmonary metastases has been cited in the literature. It is concluded that MRI can provide useful information about the nature of chemodectomas although it cannot distinguish between benign and malignant tumours, except when regional lymph nodes are involved or when distant metastases exist.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/5. glomus jugulare tumor metastatic to the sacrum after high-dose radiation therapy: case report.A 47-year-old woman with left ear pain and hearing loss was diagnosed with a glomus jugulare tumor for which she received radiation therapy as the primary treatment. Over a period of 20 years, she developed temporal bone necrosis, brain stem calcifications, local tumor recurrence, and eventually metastases to her lungs and sacrum. This case underscores the often indolent nature of glomus jugulare tumors, the late sequelae of radiation therapy for benign intracranial tumors, and the potential of these tumors to metastasize. This patient's history suggests that aggressive surgical resection should be considered early for such tumors, particularly because radiation treatment does not ablate the tumor. This is only the second reported case of a glomus jugulare tumor metastatic to the sacrum.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
