- AsymptomaticThe most common presentation of this finding is asymptomatic, and it is usually discovered incidentally. Rarely does it present as chest pain. The most severe presentation is cardiac tamponade. It almost never presents as reflux.
- FalseThere is a cystic anterior mediastinal mass without substantial mass effect upon adjacent structures, but further characterization with gadolinium-enhanced MRI is necessary, especially with such a large cyst, to definitively rule out malignancy.
- Thin walls, fluid-filled
- FalseFurther characterization with MR imaging is performed. Current imaging suggest a benign etiology, and biopsy is not recommended.
