title: Type IV sacrococcygeal teratoma causing urinary retention: a rare presentation.
abstract: Sacrococcygeal teratoma is a rare fetal neoplasm usually diagnosed antenatally and considered benign with no functional impairment. Nevertheless, fetuses with this malformation are at risk of significant perinatal morbidity and mortality, usually implying a malignant component. Management is primarily surgical, with a generally good prognosis. Herein, the authors present a rare and unusual presentation of a type IV sacrococcygeal teratoma as urinary retention in a 7-day-old infant. The diagnostic workup and subsequent surgical treatment are described. The nature of the tumor and the treatment is discussed, emphasizing the need for urgent surgical treatment because of bilateral hydronephrosis that failed to resolve after inserting a urinary catheter.
