Non-functional paraganglioma of the posterior mediastinum.
Mediastinal paraganglioma is a rare and slow growing neurogenic tumor. Here, we describe a 49-year-old woman with a non-functional posterior mediastinal paraganglioma. Video-assisted thoracoscopic surgery for tumor excision failed due to massive bleeding. The tumor was excised successfully by lateral thoracotomy with bipolar electrocautery 1 week after the first operation. Mediastinal paragangl...
متن کاملChemodectoma (non-chromaffin paraganglioma) of the ninth intercostal space.
In a 30-year-old man, radiography revealed a mass in relation to the ninth left intercostal space (Fig. 1). There was no radiological increase in the size of the mass one year later when operation was undertaken. At operation a sessile mass was removed from the ninth left intercostal space posteriorly, in the position usually occupied by a neurofibroma. The tumour was thought to arise from the ...
متن کاملParaganglioma of the mediastinum: challenges in diagnosis and surgical management
Mediastinal paraganglioms are rare, highly vascularized tumors arising from chromaffin tissue located in the para-aortic ganglia. Tumors tend to invade bordering structures and may also form metastasis. Up to 50% of patients are asymptomatic and diagnosis is incidental. Presenting symptoms are related to catecholamine hypersecretion or to a mass effect. Complete surgical resection remains the s...

متن کاملMalignant paraganglioma arising from the posterior mediastinum: a case report and review of the literature.
An unusual case of paraganglioma of posterior mediastinum occurred in a young adult with local recurrence and multiple distant metastasis. Because of its rarity, the determinants of prognosis factor between benign and malignant paraganglioma are uncertain. In this case, we investigated abnormalities of the p53 gene and ras gene mutations in tissues of primary and metastatic lesions. Neither abn...
