title: Polysplenia syndrome detected after chest symptoms in two adult patients: case report and review of literature.
abstract: BACKGROUND
  Polisplenia syndrome (PSS) is a rare subtype of heterotaxy syndrome and means ambiguous location of the major thoracic and abdominal organs with vascular anomalies and multiple spleens. We reported on the findings of computed tomography (CT) of PSS in adults, detected incidentally.
  
  
  METHODS
  Two woman underwent a CT examination of the thorax for different thoracic pathologies. There were common abnormalities such as hyparterial bronchi and absence of middle lobe fissure on CTscans suggesting heterotaxy syndrome. Therefore, the abdominal CTs were performed to detect the accompanying abdominal anomalies. Our two cases defined as PSS were diagnosed with multiple spleens in the normal location in the abdomen. The left-dominant liver and short pancreas with agenesis of the pancreatic tail and lateral part of the body were detected on CT scan. In the first case, the vascular abnormalities were as follows: variant entrance of the main portal vein into the liver and atypically located superior mesenteric vein (SMV) joining with the splenic vein to form the portal vein. In the second case, the preduodenal portal vein and hemiazygos continuation with interruption of the hepatic segment of the inferior vena cava (IVC) were the vascular anomalies. The bowels were malrotated in the second case.
  
  
  CONCLUSIONS
  Although such cases are usually admitted as abdominal emergency, our two cases were detected during examinations for thoracic and cardiac pathologies. The knowledge and awareness of PSS can be helpful to diagnose pathology and plan surgical procedures.
