Herein, a case of a solitary primary paraganglioma arising in the mesentery, found in a hypertensive 70-year-old woman, who presented with nausea and postprandial abdominal discomfort, is reported. Ultrasonography and computed tomography showed a hypervascular mass abutting the second portion of the duodenum. An exploratory laparotomy revealed a 5.5 x 5.3 x 5cm sized mass in the mesentery of the transverse colon, which was histologically proven to be a paraganglioma. No intraoperative hemodynamic changes developed, and the postoperative course was uneventful. To our knowledge, this is the first case of a paraganglioma arising in the mesentery reported in Korea. Considering the unusual locations and the associated operative risk, it is necessary to rule out the possibility of a functioning paraganglioma in the preoperative differential diagnosis of an abdominal mass.
Key Words: paraganglioma, mesentery, transverse colon, abdominal mass
