Abstract
Thoracic neurogenic neoplasms may be a diagnostic challenge both clinically and radiologically, ranging from benign, incidentally discovered tumors to aggressive, symptomatic malignancies. These tumors may originate from any nervous structure within the chest and are derived from cells of the nerve sheath, autonomic ganglia, or paraganglia. The nervous anatomy of the thorax is complex, and neurogenic tumors may be found in any mediastinal compartment or in the chest wall. Furthermore, neurogenic tumors may indicate one of many syndromes, particularly when they are multiple. This article illustrates the complex anatomy of the nervous system within the chest and details important epidemiologic and pathophysiologic features as an approach to neurogenic tumors of the thorax. Key imaging features of neurogenic tumors occurring in the chest are identified, focusing on distinguishing characteristics and the relative advantages of available imaging modalities to further refine a differential diagnosis.
