case_images: Abdominal X-ray and ultrasound revealed a dilated stomach with an air-fluid level (Figures 1A and 1B). The assessment continued with abdominal CT, which showed no evidence of any obstructive factor or tumor, and chest CT, which identified a well-demarcated anterior mediastinal mass with a maximum diameter of approximately 5 cm and no invasion of adjacent structures (Figure 1C). Gastrography was performed which showed contrast progression and a normal-sized stomach with peristalsis (Figure 1D).
