Posterior mediastinal masses secondary to lymphadenitis from esophagitis.

Two cases of children with posterior mediastinal masses due to esophagitis and lymphadenitis are presented. Both patients had gastroesophageal reflux, and in both the mediastinal masses regressed with antireflux therapy. Radiographically, the masses simulated a neurogenic tumor in one patient and an esophageal duplication in a second patient.
