68Ga-DOTATATE Uptake in Rare Metastatic/Inoperable Mediastinal Paraganglioma with Anomalous Coronary Supply

Key Points

To present a case of a mediastinal paraganglioma that exhibits unique anatomical challenges due to its blood supply.
Reported case of a histopathologically confirmed mediastinal paraganglioma
Utilized whole-body positron emission tomography/computed tomography imaging
Assessed 68Ga-DOTATATE uptake
Identified a mass that was avid for 68Ga-DOTATATE
Confirmed the tumor's supply was from the coronary artery
Highlighted clinical challenges due to hemorrhage risk in functional tumors

Abstract

Mediastinal paragangliomas (PGLs) are extremely rare neuroendocrine tumors. Clinical presentation varies and tumor resection can be challenging due to bleeding and risk of catecholamine surges in functional tumors. We report on a case 68 with a DOTATATE avid mediastinal mass which was histopathologically confirmed as a PGL that was fed by the coronary artery in whole-body positron emission tomography/computed tomography imaging using gallium-68-DOTATATE.
