spinal dysraphism

The radiographic image demonstrates a classic presentation of spina bifida occulta affecting the first sacral vertebra (S1), highlighted by the red circle. This congenital anomaly results from a failure in the normal embryological development of the neural tube, specifically inadequate formation of the vertebral arch components.

The illustration depicts a classic presentation of lumbar myelomeningocele, showing the external sac containing cerebrospinal fluid (CSF) protruding posteriorly from the lumbar region of the spine.

A lumbar myelomeningocele is the most severe form of spina bifida, characterized by the protrusion of spinal cord tissue and meninges through a defect in the vertebral column. The image shows two perspectives of a lumbar myelomeningocele in a newborn, displaying the characteristic red, sac-like structure containing neural elements protruding from the lower back. This congenital defect requires prompt surgical intervention to prevent infection, preserve neurological function, and improve long-term outcomes. Understanding the pathophysiology, clinical implications, and management strategies is crucial for healthcare professionals dealing with this challenging condition.
