Ultrasonic and computed tomographic appearances of paraganglioma simulating pancreatic mass

A Case of Primary Paraganglioma that Arose in the Pancreas: the Color Doppler Ultrasonography and Dynamic CT Features

“…Paragangliomas or extraadrenal pheochromocytomas are rare, affecting about one in 2,000,000 people (6). Although most paragangliomas are solitary and they arise sporadically, they can be multicentric or hereditary.…”

Nonfunctional Paraganglioma of the Pancreas: Report of a Case

“…[1][2][3] They are related to the autonomic nervous system, and usually occur in the head, neck, and retroperitoneal cavity. [3][4][5][6][7] It is difficult to establish the correct diagnosis of nonfunctional tumors before and during surgery, and the available literature on this unusual subject is discussed following the case report.…”

Primary Paraganglioma of the Head of Pancreas: Contribution of Combinatorial Image Analyses to the Diagnosis of Disease

“…Primary pancreatic paraganglioma is a rare disease and difficult to be exactly distin- of the pancreas, as well as other benign tumors, usually does not present any symptoms and is often found incidentally, in particular, there is no patient with the symptom of jaundice in contrast to carcinoma of the pancreas head (5). On image analyses, all patients with pancreatic paraganglioma had a cystic component and a parenchyma developing a rich blood supply from the surrounding vessels in contrast to carcinoma (4,5). Ultrasonography and CT scan are useful for the detection of pancreatic tumor including paraganglioma.…”

“…Since excessive surgical resection of the pancreas often causes deficient secretion of pancreatic hormones and digestive enzymes such as insulin, amylase and lipase, accurate diagnosis is needed for proper surgical treatment of pancreatic tumor. Paraganglioma of the pancreas is a rare disease, and its ultrasonic, computed tomographic appearances have been evaluated in several cases (1)(2)(3)(4)(5). We herein report a patient with paraganglioma in the head of pancreas, who was diagnosed as the neuroendocrine tumor of pancreas before surgery.…”
