What does abutting the left s1 nerve root mean?

Abutting the left S1 nerve root means that a structure, such as a herniated disc or a mass, is in close proximity to the left S1 nerve root, which originates from the sacral region of the spinal cord. This contact can potentially lead to compression or irritation of the nerve root, resulting in symptoms like pain, numbness, or weakness in the areas innervated by that nerve. It is important to monitor such findings through imaging and clinical assessment to determine if treatment is necessary.
