Retroperitoneal paraganglioma

Paragangliomas are benign neoplasms that arise from the autonomic nervous system and the associated paraganglia. Although benign, they have been shown to possess metastatic potential. Extra-adrenal retroperitoneal paraganglioma with vertebral metastasis is considered very uncommon. Here, we present a case of a functional extra-adrenal paraganglioma of the retroperitoneum giving metastasis to T4...

paragangliomas are tumors that originate from extra-adrenal medullary neural crest derivatives. they are rarely located in retroperitoneal space. these tumors are often discovered incidentally during imaging studies performed for other reasons.periampullary cancers include adenocarcinomas arising from the pancreas, ampulla of vater, duodenum or distal common bile duct. the exact site of origin ...

BACKGROUND Paragangliomas occur most commonly in head and neck region and much less frequently, they are found in the retroperitoneum. Composite paraganglioma-ganglioneuroma of the retroperitoneum is very rare. CASE PRESENTATION We present an unusual case of retroperitoneal composite paraganglioma-ganglioneuroma discovered on computed tomography in a 63-year-old female patient. Routine hemato...

Paragangliomas are neuroendocrine tumours and those occurring in the head and neck have well recognized familial association. Retroperitoneal paragangliomas are uncommon and we present two cases of familial malignant retroperitoneal paraganglioma. Review of the literature revealed marked differences in the incidence and malignant potential of familial and non-familial paraganglioma. In contrast...

INTRODUCTION Retroperitoneal neoplasms are rare and easily misdiagnosed. These tumors are often discovered incidentally during imaging studies performed for other reasons. Paragangliomas are tumors that arise from extra-adrenal medullary neural crest derivatives. They are usually located in the head and neck but can be found in various body sites, including the chest cavity, abdomen, pelvis and...

a 38 years old male worker presented with an advanced left side retroperitoneal mass, with metastatic involvement of 11th thoracic vertebra (t11) and resultant paraparesia and paresthesia . the histopathologic examination and immunohistochemical analysis confirmed the diagnosis of paraganglioma. decompression laminectomy and fixation of involved vertebra resulted to considerable symptomatic rel...

The Paraganglioma is the most common extra-adrenal pheochromocytoma arising from neural crest (1) (It will better to write: The paraganglioma is an extra-adrenal pheocromocytoma arising from the neural crest. 10% of pheocromocytomas are extra-adrenal and can arise form chromaffin tissue derived from primitive neuroectoderm). Minimally invasive techniques allow surgeons to perform the procedure ...

Extra-adrenal /retroperitoneal paraganglioma is a rare cause of hypertension in young with increased incidence of metastasis as compared to adrenal pheochromocytoma. We present a case of a young female with history of headache, nausea/vomiting, palpitations, uncontrolled hypertension, heat intolerance and diaphoresis. The 24-hour urine catecholamine levels were elevated. Clinical diagnosis of p...
