Infected congenital splenic cyst associated with duodenal duplication cyst and malrotation--a case report.

Congenital splenic cyst is a rare entity. A potential complication of this anomaly is infection. We report on an 18-month-old boy who had Salmonella enterocolitis and 2 weeks later was found to have an infected splenic cyst. At surgery, a duodenal duplication cyst and malrotation of the gut were incidentally found. Infected splenic cysts usually occur in older children or adults. To the best of our knowledge, congenital splenic cyst has not previously been reported in association with other malformations.
