Computer tomographic dorsal a and transverse b & c multiplanar reconstructions of the neck using a soft tissue algorithm. A soft tissue attenuating intraluminal tracheal mass (*, a & b) is visible ventral to C4. An extra luminal soft tissue attenuating mass (+, a & c) is visible left to the trachea, displacing the esophagus (arrows) laterally and decreasing the width of the trachea
