Intrathoracic paragangliomas are uncommon and only represent 1–2% of paragangliomas. They are most commonly found in mediastinal compartments (aortopulmonary (AP) window or posterior mediastinum). Computed tomography, magnetic resonance and specific nuclear medicine radiotracers are routinely used to characterize these lesions and help exclude other more common conditions. Selective angiography is currently used for preoperative embolization and mapping of the vascular supply before surgical resection, rather than for diagnostic purposes alone.
