[Iatrogenic changes in the dural sac. Radiologic semeiology]

Area of Science:

• Radiology
• Pathology
• Neurosurgery

Background:

• Radiculography is a diagnostic imaging technique used to visualize the spinal nerve roots.
• Post-operative complications and inflammatory conditions can affect nerve root appearance.
• Distinguishing between different types of spinal lesions is crucial for effective treatment.

Purpose of the Study:

• To analyze the pathological appearances observed in follow-up and post-operative radiculography.
• To determine if specific imaging features can differentiate between arachnoiditis and periduritis.

Main Methods:

• Review of pathological findings from radiculography examinations.
• Comparison of imaging characteristics in patients with confirmed arachnoiditis versus periduritis.

Main Results:

• Distinct pathological appearances were identified in follow-up and post-operative radiculography.
• Specific imaging features allowed for the differentiation of lesions caused by arachnoiditis from those caused by periduritis.

Conclusions:

• Pathological appearances in radiculography provide valuable information for diagnosing spinal conditions.
• The study successfully established criteria to distinguish arachnoiditis from periduritis based on imaging findings.
