Presentation
Recurrent dysphagia. Known T4N0M0 esophageal cancer treated with radiotherapy in 2017.
Patient Data
There is an obstructing enhancing soft tissue density esophageal mass that measures 1.91 x 2.23 x 3.27 cm (AP x CC x Tr) obstructing the lumen of the esophagus at T6-T7 level. It causes proximal esophageal dilatation with air fluid level and food debris within the dilated esophagus. There is loss of the fat planes between the esophagus and trachea, carina and descending thoracic aorta.
The heart is enlarged. There is a well-opacified aberrant right subclavian artery that courses distal to the origin of the left subclavian artery from the arch of aorta and passes in between the dilated esophagus and thoracic vertebral body.
No evidence of pleural or pulmonary metastasis
No evidence of hilar, mediastinal or axillary lymphadenopathy
No evidence of metastasis in the visualized bones
Nodular left lobe of thyroid gland. Thoracic spondylosis.
Case Discussion
This is an interesting case of an elderly patient with recurrent esophageal cancer, stage ycT4N0M0 with an incidental finding of an aberrant right subclavian artery.
