The gastric air bubble is on the right (below the diaphragm) and liver shadow on the left, indicating situs inversus. The ascending aortic shadow on the left is a little prominent. There is mild scoliosis with convexity to the left which could be partly positional. Crowding of upper ribs on the right side could be due to the scoliosis.<\/p>\n<p>Adolescent idiopathic scoliosis affects 2 to 3% of general population. 80 &#8211; 99% show right thoracic curve convexity [1]. Compton J et al noted 19 patients with adolescent idiopathic scoliosis with Cobb angle &gt; 10\u00b0 among 110 patients with dextrocardia. 15 of them had left sided thoracic curvature, which is similar to that seen in the chest X-ray shown above. Of the 6 patients with normal abdominal organ orientation, 5 had left sided thoracic curvature. Authors concluded that thoracic organ orientation affects the direction of convexity of scoliosis. Left sided thoracic curvature with dextrocardia may not be associated with intra spinal pathology [1].<\/p>\n<p>Kartagener&#8217;s syndrome with situs inversus, sinusitis and bronchiectasis is an important association of dextrocardia [2]. In males it is associated with infertility because spermatozoa are immotile due to primary ciliary dyskinesia. Primary ciliary dyskinesia is transmitted in a recessive pattern and 50% have situs inversus totalis and Kartagener&#8217;s syndrome [3].<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-32124 size-full\" src=\"https:\/\/johnsonfrancis.org\/professional\/wp-content\/uploads\/2017\/10\/left-pleural-effusion-with-dextroposition1.jpg\" alt=\"Left sided pleural effusion with dextroposition\" width=\"1200\" height=\"1234\"><\/p>\n<p style=\"text-align: center;\"><span style=\"color: #0000ff;\"><strong>Left sided pleural effusion with dextroposition<\/strong><\/span><\/p>\n<p>There is massive pleural effusion on the left side pushing the heart along with the mediastinum to the right side producing a dextroposition. The higher level of the effusion in the axilla is evident. The liver shadow is on the right side indicating situs solitus. Stomach air bubble is not visible well.<\/p>\n<p>Dextroposition of the heart can also be due to congenital hypoplasia of right lung [4,5].<\/p>\n<p><span style=\"color: #0000ff;\"><strong>References<\/strong><\/span><\/p>\n<ol>\n<li>Compton J, Voort WV, Weinstein S. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/29952884\/\">Scoliosis Curvature Follows Thoracic Organ Orientation<\/a>.
