Sirenomelia: A rare presentation of twin pregnancy: A case report

Abstract

Sirenomelia, often referred to as Mermaid Syndrome, is an exceptionally rare congenital anomaly characterized by the fusion of the lower limbs, creating a striking resemblance to a mermaid's tail. This condition is associated with a spectrum of severe musculoskeletal, genitourinary, and gastrointestinal malformations and presents unique challenges in both diagnosis and management. In this case report, we present a compelling case of sirenomelia in a 30-year-old female with a gravidity of 2 (G2P0010), who arrived at our healthcare facility as an unbooked and uninvestigated patient during her twin pregnancy. We aim to emphasize the significance of early prenatal care and comprehensive ultrasound examinations in the detection and management of sirenomelia. Our patient, without prior prenatal care, went into labor at 32 weeks of gestation. During labor, the second twin was delivered as a mermaid baby, displaying the characteristic fused lower limbs and associated congenital anomalies. Tragically, despite immediate medical attention, the newborn's life was brief, lasting for only 10 minutes. Our case report serves as a poignant reminder of the crucial role played by early prenatal care and screening in the detection and management of sirenomelia. While sirenomelia remains a rare and challenging condition, a collective effort within the medical community is necessary to enhance our understanding and explore innovative strategies for improving neonatal outcomes.
