“…Paragangliomas are observed in patients of all ages; however, they have been found to occur more frequently during the 2nd decade of life and the ratio of female to male patients is 3:2 (11-13). The most common site for paragangliomas is the organ of Zuckerkandl at the distal aorta or aortic bifurcation and less commonly, they are observed in the head, neck, thorax and bladder (14). The first case of a paraganglioma of the bladder was described by Zimmerman et al (15) in 1953.…”

Abstract. Paraganglioma, also termed extra-adrenal pheochromocytoma, may be observed at the base of the skull and neck as well as within the mediastinum and periaortic region. The clinical symptoms of paraganglioma of the urinary bladder include intermittent hypertensive attacks, micturition, headaches and palpitations due to high catecholamine levels; these types of paragangliomas are extremely rare. However, certain bladder paragangliomas do not present with any of these symptoms; thus, surgeons are not pre-warned on how to prepare for their resection. Surgery to remove pheochromocytomas may therefore result in an intraoperative hypertensive crisis and increase the mortality rate. This infrequent type of paraganglioma is only recognized through histo logical examination following surgery. The current study reports the case of a 61-year-old male with urinary bladder paraganglioma. The patient presented with hypertension, which was controlled to within a normal range using diovan and norvasc treatment; in addition, the patient's blood pressure was not altered with urination or postural changes. The patient was not administered an α-blocking agent or a blood volume expander prior to the surgery, and during the partial cystectomy no hypertensive crisis occurred.

“…PG cases with metastatic disease may be administered chemotherapeutic agents including cyclophosphamide, vincristine, and dacarbazine. Symptoms of local compression can be treated with radiotherapy for palliation (Lee et al, 2006). Since our patient was considered inoperable as a result of pericardial invasion, she already lost chance for surgical cure.…”

“…Also called glomus tumor, chemodectoma, carotid body tumor, or receptoma, these tumors are rare and slowly growing neuroendocrine tumors (Sobol and Dailey, 1990). They are most commonly located at the bifurcation of common carotid artery, jugular foramen, aortic arch, and retroperitoneum (Lee et al, 2006). Tumors arising from adrenal medulla are called pheochromocytoma.…”

“…Paragangliomas are rare neuroendocrine tumors originating from the autonomic ganglia, with pathological features indistinguishable from pheochromocytomas (72,73). Generally, these lesions are associated with hormone secretion (catecholamines), with a high rate of malignant behavior (up to 25%) (74,75).…”

Detection and management of retroperitoneal cystic lesions: A case report and review of the literature

et al. 2017

View full text Add to dashboard Cite

Abstract. The identification of cystic lesions within the retroperitoneal space is a rare event that poses clinicians the challenge of a difficult diagnosis and disease management. Retroperitoneal cystic lesions account for a group of lesions that range from common benign lesions (e.g., lymphoceles developing as a surgical complication) to rare aggressive malignant neoplasms. Currently, in the majority of cases, image-guided procedures allow for a pathological diagnosis to be achieved in these challenging lesions, thus offering the chance of an appropriate treatment; however, the overall clinical assessment of retroperitoneal cysts is highly demanding. The present study reports the management of a representative clinical case, presenting with a voluminous cystic mass able to dislocate cave vein, whose diagnosis was preceded by a deep vein thrombosis. Computed tomography-scan and ultrasound guided percutaneous drainage were performed to achieve the diagnosis. Following the discussion of the current case report, a review of the pathological and radiological characteristics of retroperitoneal cystic lesions is presented.
