title: Cystic Mass on Right Atrium of Unusual Form of Chiari's Network: A Case Report.
abstract: Chiari's networks are present in 1.5% to 4% of the population. They are a congenital disease characterized by a remnant of the right valve of sinus venosus and rarely have clinical significance. Chiari's network, as the name implies, has network-like shape, but there are other forms of appearance. We have experienced a case of a 60-year-old woman who had a cystic mass on the right atrium. Surgical treatment was performed forthe mass removal and differential diagnosis of the mass. There was no evidence of other tumor, but Chiari's network. As cystic form of Chiari's network have not been reported before, it is the first report of cystic form of Chiari's network.
