A double left brachiocephalic vein is an uncommon anatomic variation. Among these, a accessory branch with preaortic course is extremely rare. In this case, both branches of the left brachiocephalic vein were anterior to the aortic arch. We describe the computed tomography findings with volume-rendering imaging of this rare anatomic variation.
Acute gastroesophageal intussusception is a rare condition in which the stomach invaginates into the adjacent esophagus. We report a case of acute gastroesophageal intussusception with massive pneumomediastinum, pneumoperitoneum, and subcutaneous emphysema, effectively treated with conservative management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
