Esophageal carcinoma invading a kommerell's aneurysm

摘要

A 67-year-old man presented with increasing dysphagia and loss of appetite for 3 months, and history of hypertension and abdominal aortic aneurysm for 5 years. Esophagoscopy revealed a mass in the cervical esophagus, measuring 4x4 cm, with signs of external invasion; a biopsy identified squamous cell carcinoma. Computed tomography of the chest and abdomen was performed for staging (Figure 1,2). This revealed that the esophageal carcinoma had invaded an aneurysm of a diverticulum arising from an aberrant right subclavian artery (KommereH's aneurysm). The tumor was considered unresectable on the basis of invasion of an unrecorded vascular structure. The patient was started on palliative chemotherapy.
