Heterotaxy syndrome: This is the left, right? S Afr J Rad. 2015;19(2); Art. #902, 5 pages. http://dx.DOI.org/ 10.4102/sajr.v19i2.902.1027-202X (print)2075-6778 (online)10.4102/sajr.v19i2.902http://hdl.handle.net/2263/51712This article was adapted from an electronic poster entitled ‘This is the left, right?’ presented at the European Congress of Radiology in Vienna, Austria, in 2013.Heterotaxy syndrome is a rare and complex disorder of the chest and abdominal organ arrangements, and presents a diagnostic challenge to the radiologist. This article describes the morphological characteristics of heterotaxy and situs abnormalities, in particular left and right atrial isomerism, and suggests an approach in evaluating the spectrum of abnormalities associated with heterotaxy syndromes, using appropriate imaging modalities.en© 2015.
