Objective:

To summarize MRI signs of intraneural ganglion cysts (IGCs) based on the unifying articular theory, emphasizing their diagnostic utility and implications for surgical outcomes.

Key Findings:
  • IGCs are benign lesions causing mononeuropathy due to nerve compression.
  • The articular theory explains IGC formation through connections to synovial joints.
  • MRI signs are crucial for diagnosing IGCs and planning surgical interventions, particularly in relation to joint connections.
  • Improved imaging techniques have led to increased recognition of IGCs, particularly in the peroneal nerve.
Interpretation:

The findings support the articular theory, highlighting the need for targeted treatment addressing the joint connection to reduce recurrence rates of IGCs and improve surgical outcomes.

Limitations:
  • The review may not encompass all existing literature on IGCs, particularly recent studies.
  • Variability in MRI techniques and interpretations, such as differences in imaging protocols, may affect diagnostic consistency.
Conclusion:

Understanding the MRI signs and the articular theory enhances the diagnosis and treatment of IGCs, ultimately improving patient outcomes through targeted surgical approaches.
