Neurulation

Neurulation

Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Summary

Sirenomelia, a rare congenital anomaly causing fused lower extremities, typically results in a lethal prognosis. This case highlights a 26-week pregnancy diagnosed with sirenomelia, leading to pregnancy termination due to poor outcomes.

Area of Science:

Medical Genetics
Fetal Medicine
Congenital Anomalies

Background:

Sirenomelia is a rare congenital anomaly with a typically lethal prognosis.
Characterized by fusion of lower extremities and visceral abnormalities.

Observation:

A 26-year-old female patient, in her second pregnancy, presented at 26 weeks gestation.
The patient experienced anhydramnios, a significant indicator of fetal distress.

Findings:

Ultrasound in Maternal Fetal Medicine confirmed the diagnosis of sirenomelia.
The severity of associated abnormalities indicated a poor fetal prognosis.

Implications:

Pregnancy termination was elected due to the lethal nature of sirenomelia.
This case underscores the importance of early diagnosis and prognostic assessment in congenital anomalies.
