Incidentally Found Aorto-Pulmonary Middle Mediastinal Hypervascular Mass on Pulmonary CT Angiography in a Covid 19 patient

Abstract

Paragangliomas (PGs) are rare neuroendocrine tumors arising from paraganglia, clusters of neuroendocrine cells scattered throughout the body. Mediastinal paragangliomas represent less than 2% of all paragangliomas and less than 0.3 % of the mediastinal tumors. These tumors may secrete catecholamines, however in up to 50% of cases they are nonfunctional and are diagnosed incidentaly or with symptoms of mass effcet to the adjacent structures. They should be considered in the differential diagnosis of hypervascular mediastinal masses. The typical radiological features are very guiding in the diagnosis and the management of the patient. We aimed to present a case of a hypervascular middle mediastinal mass incidentally found in a 69 year old woman and diagnosed with aortopulmonary nonfunctional PG radiologically.
