Radiotherapy of paragangliomas
Clinical Otolaryngology, 1984From 1964 to 1980 28 patients with extensive paragangliomas were treated with radiation therapy. Nine patients had a carotid body tumour and 19 had a temporal bone tumour. During the 16 year period the radiation dose was gradually reduced from 60 Gy in 6 weeks to 40 Gy in 4 weeks. Continuous tumour control was achieved in all patients (follow-up 1.5-18

AbstractParaganglioma are rare chromaffin cell tumors that develop from the neural crest cells. Parasympathetic ganglia‐derived tumors are found almost exclusively in the neck and skull base and typically do not secrete catecholamines. In contrast, most sympathetic ganglia‐derived tumors are found in the abdomen and produce an excess of catecholamines.

Phaeochromocytoma and Paraganglioma
2016Phaeochromocytomas and paragangliomas are relatively uncommon tumours which may be manifest in many ways, specifically as sustained or paroxysmal hypertension, episodes of palpitations, sweating, headache and anxiety, or increasingly as an incidental finding. Recent studies have shown that an increasing number are due to germline mutations. This review

Pheochromocytoma and Paraganglioma
2009Pheochromocytomas and extra-adrenal sympathetic paragangliomas are catecholamine-secreting neuroendocrine tumors derived from the chromaffin cells of the embryonic neural crest. Parasympathetic paragangliomas are related tumors which most often arise within the head and neck, and are anatomically associated with the parasympathetic nervous system ...

Mesenteric paraganglioma is a solitary primary paraganglioma that occurs in the mesentery. It is a rare and unusual tumor, especially in non-typical sites such as the inferior mesenteric artery. We incidentally diagnosed a pelvic mass in a 22-year-old woman, who had not experienced vomiting, headache or hypertension.

Phaeochromocytoma and paraganglioma
Baillière's Clinical Endocrinology and Metabolism, 1993Use of current analytical techniques should lead to the successful diagnosis of most catecholamine-secreting tumours, and the experience and confidence which has evolved with the use of HPLC-ECD for plasma and urinary catecholamine estimation, as well as their greater diagnostic sensitivity and specificity, should soon render the older urinary assays ...

Aorticopulmonary paraganglioma
General Thoracic and Cardiovascular Surgery, 2011We describe a 61-year-old woman with an anterior mediastinal paraganglioma. The patient complained of a chronic cough that had lasted about 6 months. Her chest computed tomography (CT) showed a highly enhanced mediastinal tumor in the aorticopulmonary window. We surgically resected this tumor thorough a left anterior thoracotomy.

Paraganglioma of the Gallbladder
Archives of Surgery, 1973To the Editor .—In the discussion of their well-documented case of paraganglioma of the gallbladder ( Arch Surg 105:637-639, 1972) Miller and co-authors stated that nonneoplastic paraganglionic tissue had not as yet been described in the gallbladder. In the Laboratory of Surgical Pathology at the College of Physicians and Surgeons, we have observed ...
