Truncus bicaroticus and arteria lusoria—a rare combination of aortic arch anomalies
A 54-year-old female presented to the outpatient Department of Internal Medicine with the history of progressive mild dysphagia for past 3 to 4 months with no history of significant weight loss. She had no significant past history. Her blood pressure, heart rate, respiratory rate, and body temperature were within normal limits. The complete blood counts, hemogram, and coagulation profile were also normal. Her chest radiograph and barium swallow studies were unremarkable.
She was referred for contrast-enhanced computed tomography (CECT) of the neck and chest. The CT was performed using 64-slice Somatom Sensation (Siemens Healthcare, Germany). After the baseline non-contrast study, aortic arch anomalies (aberrant right subclavian artery and truncus bicaroticus) were suspected, and that is why CT aortogram was performed by injecting 90 ml of Iopromide (Ultravist-370) at a rate of 4 ml/s, followed by delayed venous phase to look for the esophageal lumen, neck, mediastinum, and lungs.
It is verified that all the authors had the access to the data and role in the writing of the manuscript.
