A Rare Case of Sirenomelia with Absent Sacrum

Sirenomelia with Absent Sacrum

Abstract

Sirenomelia is a rare lethal condition characterised by fusion of partial or complete fusion of lower limbs with male predominance. In the African context, such mermaid-like babies are called mammy -water babies, which carries an evil connotation associated with witchcraft. It is usually associated associated with diabetes milletus and tobacco usage. Risk factors are diabetes milletus, teratogenic factors, genetic factors and maternal age less than 20 years. Ultrasound is primary modality of choice of investigation in cases of sirenomelia in prenatal ultrasound. First trimester diagnosis of this disorder and induced abortion may be safest medical option. Most of the cases of sirenomelia results in still birth or die within a day or two due to congenital complications.
