title: Acute rupture of a cystic ovarian teratoma complicating premature labor.
abstract: A cystic ovarian teratoma (COT), previously undiagnosed either clinically or by ultrasonography, presented as acute intra-abdominal disease complicating premature labor. This report emphasizes the potentially catastrophic complications of COT and stresses that, despite the availability of ultrasonography, there is still a need for conventional radiography in abdominal catastrophes in pregnant women.
