A 13-month-old girl presented with right upper lobe pneumonia and hypocalcaemic seizures: investigations showed hypoparathyroidism and impaired cell-mediated immune responses. Other features of the DiGeorge syndrome included hypertelorism, short philtrum of the lip, right-sided aortic arch, and aberrant origin of the left subclavian artery. Successful restoration of the immunodeficiency was ach...

A right-sided aorta with an isolated left subclavian and left common carotid artery is a rare arch defect. We are presenting the case of a 56-year-old woman who had initially presented with headache and 3 episodes of right-sided facial and extremity numbness. A presumptive diagnosis of transient ischemic attack prompted imaging studies where a computer tomography angiogram showed aberrant vessels.

Aberrant subclavian arteries are congenital vascular anomalies that usually do not cause any symptoms. When symptomatic they are considered as a rare cause of dysphagia. This presentation is known as dysphagia lusoria. They are diagnosed by barium swallow or contrast-enhanced computed tomography, although it may be an incidental finding. Management varies from life modifications and drug therap...

An aberrant right subclavian artery can be diagnosed by PET/CT, as demonstrated in this case of a 70-y-old man undergoing PET/CT for staging of squamous cell carcinoma of the right lung. It is important to report this finding during the evaluation of oncologic patients, to prevent severe complications that may arise from various oncologic interventions.

This paper describes a rare case in which the left subclavian artery originates from a common stem arising from the aortic arch and splits into a brachiocephalic trunk and a left subclavian artery. The course of other large vessels of the aortic arch in this case are typical.

Dysphagia lusoria is present in 0.2-2.5% of the population representing the most common anomaly of the aortic arch (De Araújo et al., 2015, Int. J. Surg. Case Rep., 7, 32). It usually presents in infants, but can present at any age. Symptoms include cough, dysphagia, thoracic pain, and pulmonary infection. Barium contrast studies, CT, and MR angiography are useful studies for evaluating the con...
