Facial lymphatic malformation: the root cause of trigeminal neuralgia is not its root. Illustrative case

Key Points

To explore alternative causes of trigeminal neuralgia (TN) that may not relate to the root entry zone compression.
Illustrative case analysis of trigeminal neuralgia presentation
Detailed anatomical assessment of the trigeminal nerve
Discussion of treatment implications based on findings
Identified a case of TN caused by compression distal to the root entry zone
Proposed that full anatomical considerations may reveal other compression points
Challenged the conventional view regarding the exclusivity of root entry zone compression in TN cases

Abstract

Trigeminal nerve compression distal to the root entry zone, although uncommon, is a treatable cause of TN. Treatment for classical TN should consider the full anatomical course of the nerve and potential compression points. This case challenges the conventional understanding that TN is exclusively caused by compression at its more vulnerable root entry zone. https://thejns.org/doi/10.3171/CASE25973.
