Rare case of temporally spontaneous regression of retroperitoneal paraganglioma

Case note: retroperitoneal nonfunctioning paraganglioma.

Paragangliomas are extra-adrenal chromaffin tumours that develop at the expense of neuroectodermal cells of the autonomous nervous system. Retroperitoneal and nonfunctioning forms are very rare. They are often asymptomatic and can reach a substantial size. Treatment usually involves surgery with the goal of total excision. We report the case of a patient who presented with indistinct abdominal ...

Retroperitoneal Paraganglioma – a rare cause of arterial hypertension

Paragangliomas, as well as pheochromocytomas, are neuroendocrine tumours, which often secrete catecholamines. This hypersecretion causes symptoms that are often difficult to control. Pheochromocytomas originate in the medulla of the adrenal glands and make up 80-85% of cases, whereas paragangliomas originate extra-adrenally and make up 15-20% of cases. Paragangliomas are rare tumours, and altho...

Retroperitoneal non-functioning paraganglioma: A case report

Management dilemmas of retroperitoneal paraganglioma: report of a case.

A 17-year-old boy presented to emergency department with abdominal pain in the left upper quadrant along with a palpable mass. A CT scan revealed a 10 x 8.5 cm mass in the retroperitoneal area, suggestive of a sarcoma. The patient underwent surgical resection of the lesion, the histological examination of which confirmed a paraganglioma. An 131I-Metaiodobenzylguanidine (MIBG) scan excluded dist...
