Abstract

Sirenomelia is a lethal congenital malformation characterized by single or fused lower limbs associated with other severe genitourinary and lower gastrointestinal tract anomalies. Associated anomalies include malformation of vertebrae and pelvis, oligohydroamnios, renal agenesis, imperforate anus, internal and external genital anomaly and single umbilical artery. Recently, sirenomelia is diagnosed by ultrasound at first trimester or early second trimester. Termination of pregnancy is recommended as soon as diagnosis is made. We report a case of sirenomelia in a monoamniotic twin gestation detected at IUP at 12 weeks which was maintained till IUP at 37 weeks and delivered by cesarean section. On autopsy, typical finding of sirenomelia was noted, whereas the contralateral twin showed no abnormalities.
