[Prenatal sonographic diagnosis of a cystic coccygeal teratoma with retroperitoneal extension].
The most common teratoma of th newborn is the sacrococcygeal, which contains tissues of all three germinal layers. It is located over and under the sacrum or the coccyx and may extend in front of the sacrum into the retroperitoneal region. The teratoma can lead to compression of the ureters with resultant hydronephrosis or to obstruction of the rectum. The most important complication is the malignant change which usually occurs between the fourth month and the third year. Because of the complications early diagnosis of the teratoma is necessary and extirpation should be carried out as soon as possible. The present paper reports on the sonographic findings in a sacrococcygeal teratoma with retroperitoneal extension at 37 weeks gestation. The aetiology and pathogenesis of this malformation and the clinical findings are discussed.
