Abstract

Ectopia of the pancreatic tissue is a developmental anomaly found in ~2% of all autopsies, and 70~90% of these anomalies are located in the gastrointestinal tract. Mediastinal localization of an ectopic pancreas is extremely rare. Herein, we report two cases with mediastinal ectopic pancreas clarified by pathology and shown by thoracic contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI). In addition, a brief review of the relevant literatures is presented. Although CT and MRI manifestations of this lesion are nonspecific, certain notable findings need to be focused on. When there is a mass in the anterior mediastinum with marked and heterogeneous enhancement, along with necrotic and liquefied non-enhanced areas in the center, ectopic pancreas should be considered and differentiated from other neoplasms in this region.
