Mediastinal Mass Caused by Granulomatous Reaction to Foreign Plant Material Following a Spontaneous Esophageal Rupture.

The discovery of a mediastinal mass presents a wide array of differential diagnoses which largely depends on the boundaries of the mass and its contents. Both computed tomography (CT) and magnetic resonance imaging (MRI) of the chest can determine radiologic compartmentalization to aid in diagnosis. Tissue biopsy for pathology, however, is necessary for final diagnosis. The establishment of a diagnosis should not be delayed, as mediastinal mass may be due to serious causes such as malignancy or infection. Here, we present a rare case of a 72-year-old male with a mediastinal mass that formed as a complication of traumatic esophageal perforation during cardiac arrest. Pathology revealed foreign plant material with granuloma formation secondary to food residue as the etiology of the mass.
