Diagnosis: Esophageal schwannoma
Radiologic Findings: Figure 1. Chest radiograph shows increased opacity at the left paratracheal area associated with right sided tracheal deviation.
Figure 2. Unenhanced chest computed tomography (CT) shows that the mass in the left tracheal area is homogenous, and iso-attenuating with chest wall muscle.
Figure 3-5. Contrast-enhanced chest CT images show an upper esophageal mass of well-defined and homogenous density that adheres to the wall of the esophagus suggestive of a submucosal tumor.
Figure 6. FDG positron emission tomography image shows the mass with avidly increased uptake of FDG.
Brief Review: Gastrointestinal schwannomas are uncommon benign neoplasms that are uniquely different from conventional soft t issue and central nervous system schwannomas. Histologically, gastrointestinal schwannomas are S-100 protein
