Mediastinal Mass: An Unusual Location for a Paraganglioma.

A 50-year-old man presented to the hospital for workup of a symptomatic inguinal hernia. At presurgical workup, findings from a contrast material-enhanced CT of the chest, abdomen, and pelvis revealed a large, well-defined and enhancing middle mediastinal mass arising from the right ventricular outflow tract. The mass was ultimately deemed resectable due to preserved fat planes between the mass and other mediastinal structures and the preservation of the right and left coronary arteries. The tumor was diagnosed as a mediastinal paraganglioma at histologic assessment. Keywords: Adults, Angiography, CT-Angiography, MR-Angiography, Cardiac, Neoplasms-Primary ©RSNA, 2021.
