Paraganglioma of the urinary bladder is rare, accounting for <0.05% of all bladder tumors. Common clinical findings in patients with bladder paraganglioma include hematuria and intermittent hypertension during urination, along with generalized symptoms due to increased levels of catecholamines. Although unsuspected bladder paraganglioma may result in intraoperative hypertensive crises, these ma...

INTRODUCTION Paraganglioma is an extremely rare catecholamine-producing tumor during pregnancy. Paraganglioma carries high risks of fetal and maternal mortality during pregnancy. We report a pregnant woman with paraganglioma in the second trimester. CASE DESCRIPTION A 24-year-old pregnant woman presented with severe hypertension in the 17th week of gestation. Hormonal examination and Magnetic...

Carotid body paraganglioma is a neuroendocrine neoplasm of the mandibular region. Due to its prominent stromal alternations, carotid body paraganglioma is a great emulator of other neoplasms in the head and neck region especially in metastatic tumors and its definite diagnosis is a great challenge. To the best of our knowledge, the most frequently reported variant is sclerosing and paragangliom...

Paragangliomas are neuroendocrine tumors that originate from cells migrating from the neural crest. They have a diverse localizations, and are common in the head, neck, mediastinum or retroperitoneum. Their growth in the filum terminale region is very infrequent. We report the case of a patient who suffered an acute cauda equina syndrome. We give a detailed description of the diagnostic process...

Recently, nuclear genes encoding two mitochondrial complex II subunit proteins, SDHD and SDHB, have been found to be associated with the development of familial pheochromocytomas and paragangliomas (hereditary pheochromocytoma/paraganglioma syndrome: HPPS). Growing evidence suggests that a mutation of SDHB is highly associated with abdominal (or thoracic) paraganglioma and the following distant...
