A right aortic arch is an anatomic variant only occurring in approximately 0.1% of the population. A mirror-image right artic arch without congenital cardiac anomaly is fairly uncommon. We report on a rare case of dysphagia due to isolated aortic diverticulum in a mirror-image right aortic arch. A 72-year-old man presented with dysphagia which was due to posterior compression of the esophagus b...

A 24-year-old woman was referred to pulmonologist with worsening breathlessness and wheeze. During childhood, she was diagnosed with asthma and subsequent exacerbations were treated with bronchodilators for many years. The chest X-ray and a spirometry testing raised a doubt of extrinsic tracheal compression and a subsequent enhanced chest CT (computerized tomogram) scan confirmed a right-sided ...

Vascular ring caused by double aortic arch most commonly occurs as an isolated anomaly (Keith, Rowe, and Vlad, I967). However, its association with pulmonary stenosis (Bahnson and Blalock, I950), tetralogy of Fallot (Griswold and Young, I949; Stewart, Kincaid, and Edwards, I964), truncus arteriosus (Kerwin, I936), ventricular septal defect and left superior vena cava (Lincoln et al., I969), and...

A female weanling northern elephant seal (Mirounga angustirostris) presented to The Marine Mammal Center in Sausalito, California, USA, in poor body condition. An esophageal obstruction was diagnosed by contrast radiography and esophagoscopy, but despite extensive diagnostics and supportive care, the seal died 6 days later. On postmortem examination, the right aortic arch was persistent, formin...

The article describes a successful clinical outcome in the case of 5-month old female with diagnosis incomplete vascular ring aberrant right subclavian artery and ostium secundum atrial septal defect associated partial anomalous pulmonary venous return scimitar syndrome type, coexisting sequestration. During hospitalization, surgical correction heart resection lung sequestration were performed....

High-resolution gravity data from the Gravity Recovery and Interior Laboratory (GRAIL) mission provide the opportunity to analyze the detailed gravity and crustal structure of impact features in the morphological transition from complex craters to peak-ring basins on the Moon. We calculate average radial profiles of free-air anomalies and Bouguer anomalies for peak-ring basins, protobasins, and...

An unusual case of a colonic vascular anomaly resembling angiodysplasia associated with right sided diverticular disease is presented. The patient, a 74 year old man, presented with a four day history of rectal bleeding and subsequently underwent hemicolectomy. The resected specimen was flushed out with heparin-saline solution and injected with a barium-gelatine mixture. Preoperative barium ene...
