Abstract

Background:

Cross-sectional imaging can be used to trace the course of the vagus nerve and its laryngeal branches to detect many of the causes of vocal fold paralysis. The most frequent aetiologies are surgical injury and tumoural involvement of the recurrent laryngeal nerve anywhere along its course.

Method:

This review article focuses on the uncommon and rare causes of vocal fold paralysis that have been detected or diagnosed on cross-sectional imaging.

Results and conclusion:

Uncommon causes included a tortuous oesophagus, tracheal diverticulum, cervical osteophytes and cardiovocal syndrome. These examples are presented with clinical case histories and radiological appearances, and are discussed in the context of the current literature.
