ABSTRACT
Advances in prenatal diagnosis including improvements in ultrasonography have revealed the natural history of fetal sacrococcygeal teratomas, and this natural history differs substantially from that for postnatally diagnosed sacrococcygeal teratoma. A fetal sacrococcygeal teratoma may lead to perinatal morbidity and mortality by a variety of mechanisms. Adverse clinical sequelae of a sacrococcygeal teratoma can be prevented by accurate prenatal assessment and appropriate obstetrical and perinatal management. Development of fetal hydrops and/or placentomegaly predicts fetal demise. Fetal surgical intervention has proven successful in highly selected cases.

Indirect inguinal hernias, hydroceles, and umbilical hernias are extremely common in infancy and childhood. Less commonly encountered are femoral, direct inguinal, epigastric, and Spigelian hernias. Patient history and physical examination are usually sufficient for the diagnosis of a hernia. If the diagnosis is uncertain, ultrasound examination or herniograms are occasionally employed. Magnetic resonance imaging may be useful in diagnosing abdominal wall hernias in obese patients for whom physical examination is difficult.
