What is mild contour flattening of the ventral aspect of the thecal sac associated with mild encroachment of the neural foramen?

Mild contour flattening of the ventral aspect of the thecal sac suggests a slight alteration in the shape of the protective membrane surrounding the spinal cord, often due to nearby structural changes like disc bulging or bone spurs. This condition can lead to mild encroachment of the neural foramen, which may affect the nerve roots exiting the spinal column. While often asymptomatic, it can sometimes contribute to localized pain or neurological symptoms depending on the degree of compression. Monitoring and conservative management are typically recommended unless significant symptoms arise.
