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.

Jugulotympanic paragangliomas are the most common tumors of the middle ear and temporal bone. Although these larger tumors can prove to be formidable, the advent of microscopic and skull base surgical techniques has greatly enhanced the ability to treat and manage these tumors.

The management of vagal paragangliomas is extremely challenging. Treatment of these lesions must be tailored individually for each patient. The best treatment modality depends on the patient's age and health and the size and extent of the tumor. This article discusses clinical presentation, multicentric and malignant vagal paragangliomas, evaluation ...

Abstract: Paragangliomas are rare tumors that arise from extra‐adrenal paraganglia. The effective diagnosis and management of the paraganglioma patient involves the close collaboration of endocrinologists, endocrine surgeons, anesthesiologists, geneticists, laboratory specialists, radiologists, oncologists, and pathologists.

Paragangliomas are uncommon neuroendocrine tumors. In the head and neck region they are most commonly associated with the carotid body, vagus nerve, jugulotympanic paraganglia, and occasionally the superior and inferior laryngeal paraganglia. Laryngeal paragangliomas and subglottic paragangliomas are rare.

Abstract Paratesticular paragangliomas are a rare occurrence. We present the case of a 43-year-old man who presented with paresthesia and paraparesis and was found to have pathologic fracture involving D1 vertebra as a manifestation of metastasis from a nonsecretory right paratesticular paraganglioma.

Extra-adrenal pheochromocytomas and paragangliomas are rare tumors of neural crest origin, most commonly found in the retroperitoneum. Because these tumors are so uncommon, relatively little is known about their natural history. Comparisons between adrenal pheochromocytomas and extra-adrenal pheochromocytomas have appeared in the medical literature ...

Spinal paragangliomas (SP) are benign and overall rare extra-adrenal neuroendocrine tumors often diagnosed during workup for lower back pain. Complete surgical resection achieves both symptomatic relief and cure. We present a 32-year-old man with a longstanding history of lumbago and bilateral lower extremity pain found to have a lumbar paraganglioma ...

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.
