Prenatal Diagnosis of Teratoma in a Torqued Undescended Testis Masked as Unclear Intra-Abdominal Mass
Abstract
Constantly improving ultrasound technologies facilitate prenatal detection of various fetal diseases, including low-incidence disorders that are typically diagnosed postnatally, such as testicular teratoma. These can appear as an unclear cystic intra-abdominal structure, caused by an undescended torqued testis. In the case of such uncertain cystic intra-abdominal lesions, a cryptorchidism could lead the investigator to narrow the possibilities to the urogenital tract. Herein, we report the second case of a prenatally detected cystic-solid lesion being a testicular teratoma by a torqued undescended testis and the seventh case of a prenatally seen testicular teratoma. In late gestation, a structured evaluation of the testes would be beneficial to detect such malformations.
