Cardiac Paraganglioma - A Rare Subset of a Rare Tumor
This report presents the case of a middle-aged female who was referred to our hospital with unspecific clinical symptoms. Primary investigations and the rarity of a cardiac association with the identified tumor, initially led us on the wrong track. However, careful planning of the operation and performing the resection in an interdisciplinary setting was the key to success. Histopathology revealed a benign cardiac paraganglioma. On the basis of this case, we show the diagnostic challenge of this rare subset of paragangliomas

Case Presentation
A Caucasian, overweight female patient, 42 years old at the time of referral, consulted her family doctor because of intermittent fever, attacks of sweating, dyspnea and dull epigastric pain and also relapse of previously experienced back pain. She was a non-smoker and had no other significant medical history. Clinical check-up and blood test showed no evidence of an infectious disease. As one of the further investigations, a computed tomography (CT) of the chest and abdomen was decided, in order to exclude a pulmonary embolism. Surprisingly, a mediastinal mass of 6.6 × 3.9 cm in size was revealed. It was located in close contact to the tracheal carina and the left atrium. Some enlarged right hilar nodes were seen, but no other suspicious findings were documented. A magnetic resonance imaging (MRI) could not completely exclude an infiltration of the surrounding tissue and organs....
