Therefore, this condition is also known as “mirror man.” SI is a rare genetic malformation affecting 0.01% of the population. It is characterized by the total rotation of the thoracic and abdominal organs, often called mirror image reversal. The incidence rate of SI ranges from 1 in 8000 to 1 in 25,000.
Patients are diagnosed with this rare condition using radiography, ultrasonography, computed tomography, contrast-enhanced computed tomography, and magnetic resonance imaging. SI combined with tumor is rarer; however, in 1936, Allen et al. described a patient with SI and gastric cancer. Moreover, in 2009, Sceusi and Wray also presented a patient with SI complicated with a moderately differentiated ductal…
