Ovarian torsion and amputation resulting in partially calcified, pedunculated cystic mass

Three children with torsion and amputation of the right ovary are presented. The detached ovary resulted in a cystic mass containing necrotic material and a solid, partially calcified mural node. The cysts were attached to the omentum, to the mesentery of the transverse colon, or to the lower edge of the liver by a long twisted pedicle containing thin-walled vascular spaces. The radiographic and sonographic findings were quite similar and clearly reflected the operative and pathologic changes.
