Preduodenal portal vein (PDPV) is a rare developmental anomaly. In infants, this is often associated with duodenal obstruction or biliary atresia. It is generally asymptomatic in adults (Ooshima et al., Hepato-Biliary-Pancreat Surg 5(4):455-458, 1998). Here, we report a singular case of adult PDPV that was discovered accidentally during emergency laparotomy for peritonitis due to gastric perforation in a 38-year-old lady. A plethora of congenital anomalies was uncovered, which is consistent with the reported cases of classical polysplenia syndrome, viz., multiple spleens of equal volume, visceral heterotaxia, right (Rt.)-sided stomach, a left (Lt.)-sided or a large midline liver, malrotation of intestine, a short pancreas, PDPV and IVC abnormalities (Gayer et al., Abdom Imaging 24:178-184, 1999). In addition, abnormalities like anamolous origin of Lt. gastric and splenic arteries from the abdominal aorta with absent celiac trunk, hepatic artery arising from the superior mesenteric artery, hepatic veins draining directly to Rt. atrium, etc. along with hypertrophic and lipomatous interatrial septum have also been detected during further investigations. As of now, we have come across 29 cases of adult PDPV reported in world literature and we are reporting our unique case with a review of literature on anomalies of visceral organs associated with PDPV.
