A rare case of sirenomelia

Sirenomelia also called mermaid syndrome is a congenital, rare, lethal, multisystemic human malformation of unknown etiology. The characteristic feature of sirenomelia is the fusion of the lower limbs, resulting in the appearance of a mermaid’s tail, and thus the name “mermaid syndrome.” This condition is also characterized by various severe urogenital abnormalities and the presence of a singular umbilical cord blood vessel, and it is more common in infants of diabetic mothers and in monozygotic twins. The incidence is around 1 in 60,000–70,000 pregnancies. The majority of affected fetuses are stillborn, whereas the rest of the live-born die in the early neonatal period due to complications of the gastrointestinal and urogenital systems. We are reporting a case of sirenomelia in a neonate born to an unregistered multipara mother. The baby had perinatal asphyxia, sirenomelia, dextrocardia, low set ears, lymphatic malformation, bilateral renal agenesis, absent external genitalia and anus, single umbilical artery, and congenital corneal clouding. There was no antenatal ultrasonography done and the baby died at 6 h of life.

Sirenomelia

Sirenomelia is a rare and fatal congenital defect characterized by varying degrees of lower limb fusion, thoracolumbar spinal anomalies, sacrococcygeal agenesis, genitourinary, and anorectal atresia. We report a case of baby, born with narrow chest, bilateral hypoplastic thumb, fused lower limbs with a single foot and 5 toes, absent external genitalia, imperforate anus and umbilical cord with single umbilical artery. When diagnosed antenatally, termination should be offered

Sirenomelia with Potter syndrome: a case report and review of literature

Sirenomelia or mermaid syndrome is a rare congenital anomaly characterized by variable degree of fusion of lower extremities. Awareness to this rare condition is important for prenatal diagnosis and prognosticating the fetus. The exact etiopathogenesis is still an area of research. Two pathogenic hypotheses are the vascular steal hypothesis and the defective blastogenesis hypothesis with exceptions reported in literature.

Sirenomelia, the Mermaid syndrome: a case report

Sirenomelia, also known as mermaid syndrome, is a rare congenital anomaly characterized by a single lower extremity which is associated with abnormalities in other organ systems, commonly affecting the gastrointestinal and the urogenital systems. It is sporadic with no increased risk in subsequent pregnancies. In almost all the cases of sirenomelia, a single umbilical artery (SUA) is present which arises from the abdominal aorta. The exact etiology of sirenomelia is unknown. Sirenomelia can be confidently diagnosed in the 1st trimester while the diagnosis in the 2nd and 3rd trimesters is difficult due to the lack of amniotic fluid in the later gestation. Antenatal diagnosis of this universally lethal condition is desirable so that possible termination of pregnancy can be offered at the earliest.

Sirenomelia, the mermaid baby: a case report

Sirenomelia sequence or mermaid syndrome is a rare congenital structural anomaly characterized by different degrees of fusion of lower limbs, thoracolumbar spinal anomalies, sacrococcygeal agenesis, genitourinary and anorectal atresia. The incidence of sirenomelia is 0.8-1 cases/ 105 births with male to female ratio being 3:1. A malformations patient with 40 weeks of gestation admitted with complaints of decreased fetal movements for one week. An emergency C-section was done in view of term pregnancy with severe oligohydramnios and intrauterine growth restriction with poor bishop’s score. A 1.9 kg live baby with fused lower limbs was delivered. The new born baby had narrow chest, fused both lower limbs and feet with 11 toes, small rudimentary external genitalia, imperforate anus and single umbilical artery. The baby also had features of potter’s facies including low set large ears, receding chin and prominent infraorbital folds. Sirenomelia is a rare fatal congenital anomaly. Early detection by prenatal ultrasound will help in timely termination of pregnancy.

Simpus Apus Sirenomelia – A case report of a rare congenital anomaly.

Sirenomelia, also known as “mermaid syndrome”, is a rare congenital deformity of uncertain etiology. Sirenomelia is characterized by complete or partial fusion of lower limbs, giving the appearance of the tail of a ‘mermaid’. This syndrome is almost always lethal due to associated congenital visceral abnormalities such as severe lung hypoplasia, and abnormalities of the kidneys, large intestines, and genitalia. We hereby, report a case of sirenomeila due to rarity of this condition and term live birth.

Sirenomelia - A case report.

Mermaid baby also known as sirenomelia is a rare and usually lethal congenital abnormality with multisystem involvement. Characteristic feature consists of varying degrees of lower limb fusion which in severe form results in single lower limb with non-discernible limb bones. We herein report a case of sirenomelia with variable malformation.
