Mediastinal Gangliocytic Paraganglioma: A Rare Case Report
摘要
Gangliocytic paraganglioma (GP) is a rare benign tumor of neuroectodermal or neuroendodermal origin predominantly occurring in the duodenum. Here, we present the case of an incidental left superior mediastinal mass in a 57-year-old female patient with pathologically proven mediastinal GP (MGP). The tumor had a hypervascular structure with classic triphasic epithelioid, Schwannian, and gangliocytic cell types haphazardly arranged. Heterogeneity on contrast-enhanced computed tomograph and magnetic resonance imaging (MRI) T2-weighted (WI) highlighted the various cellular portions of MGP where the salt and pepper pattern signified vascular-rich characteristics. To our knowledge, the MRI salt and pepper sign of MGP has not been previously reported.
