    Intraneural ganglion cysts (IGCs) are benign lesions within peripheral nerves, often causing mononeuropathy due to nerve compression.

  • 2

    The unifying articular theory explains IGCs as joint-related pathologies, emphasizing the importance of imaging for diagnosis and surgical planning.

  • 3

    Research over 20 years has introduced MRI signs that aid in diagnosing IGCs and understanding their formation and treatment.

  • 4

    The articular theory identifies an articular branch connection to a joint as the pathway for synovial fluid egress, impacting treatment strategies.

  • 5

    Improved imaging techniques have increased the recognition of IGCs, particularly in the peroneal nerve, with a prevalence of about 18% in peroneal mononeuropathy.
