Spinal cord malformations

Area of Science:

• Neurology
• Pediatrics
• Medical Genetics

Background:

• Spinal cord malformations represent a significant category of congenital anomalies.
• These malformations are broadly classified into open and occult dysraphisms, each with distinct characteristics and management strategies.

Purpose of the Study:

• To delineate the two primary categories of spinal cord malformations: open and occult dysraphisms.
• To outline the diagnostic approaches, treatment modalities, and long-term follow-up for these conditions.

Main Methods:

• Review of current literature and clinical practices regarding spinal cord malformations.
• Analysis of diagnostic methods including prenatal screening, ultrasound, and physical examination.
• Discussion of surgical interventions and management of associated complications.

Main Results:

• Open dysraphism, primarily myelomeningocele (MMC), occurs in approximately 1/1000 live births and can be reduced by folic acid supplementation.
• Prenatal diagnosis of MMC is common, often leading to termination or early surgical repair, with a high incidence of requiring ventricular shunts.
• Occult dysraphisms encompass a diverse group including lipomas, diastematomyelia, and neurenteric cysts, requiring careful examination for cutaneous stigmata for early detection.

Conclusions:

• Effective management of spinal cord malformations necessitates a clear distinction between open and occult types.
• Timely prenatal diagnosis and prompt postnatal intervention are critical for optimizing outcomes and minimizing permanent neurological, urological, and orthopedic deficits.
• Lifelong surveillance is essential to address potential late complications associated with these congenital anomalies.
