“…Importantly, appropriate breathing instructions are paramount in obtaining optimal imaging, and radiology staff usually instruct patients to practice quiet respiration during imaging . Several findings on axial scans sensitive for UVFP include ipsilateral ventricle and piriform sinus dilation, as well as medial rotation of the aryepiglottic folds; in fact, one retrospective series suggested that the presence of two of these findings is predictive of UVFP . Dilation of the ipsilateral oropharynx and atrophy of pharyngeal constrictors are suggestive of a proximal vagal nerve injury rather than a lesion impacting the recurrent laryngeal nerve .…”

“…One of the subtle signs of vocal cord paralysis on direct visualisation and radiological imaging is thinning of the thyroarytenoid muscle and enlargement of the space directly above; the laryngeal ventricle5 (figure 4). Therefore, the space above the cord may be more amenable to harbouring foreign bodies.…”

SUMMARYA 74-year-old woman presented with a history of prolonged dysphonia, a red flag symptom for laryngeal cancer. Flexible nasal endoscopy revealed a lesion which looked suspicious for malignancy and therefore she went onto have a microlaryngoscopy and an attempt at biopsy. It was during this procedure that a foreign body was removed whole from a dilated laryngeal ventricle. We believe that some subtle anatomical changes caused by a pre-existing unilateral vocal cord palsy contributed to the impaction of this foreign body. BACKGROUND

“…Along the inferior surface of the arch, the left RLN arises and passes posterior and lateral to the ligamentum arteriosum as it travels superomedially in the aorticopulmonary window. The left RLN, which is approximately twice the length of the right, travels through the middle mediastinum, ascending along the tracheoesophageal groove and posterior to the thyroid to reach the larynx (15).…”

While in many cases they are not directly visualized, awareness of the thoracic nerves and their courses at cross-sectional imaging is important for radiologists. An understanding of the normal function of each nerve is important, as many patients present with neurologic signs and symptoms that can be used to reinforce search patterns for disease and detection of supportive radiologic abnormalities. In the case of primary neoplasms, understanding the expected presence of a nerve in the location of a mass can enhance and improve the accuracy of differential diagnoses. Even in the absence of neurologic symptoms, secondary involvement of these structures by malignancy or close proximity to other intrathoracic disease can prompt significant alterations in oncologic or surgical management. The major components of the thoracic nervous system with which the thoracic radiologist must be familiar are the phrenic, vagus, recurrent laryngeal, intercostal, and long thoracic nerves in addition to the sympathetic chain and brachial plexus. The anatomic structure and course of each component are described including its major functions. Major clinical signs and symptoms attributable to nerve dysfunction or disease are reviewed as well as any associated radiologic signs. Emphasis is placed on primary and secondary malignant involvement of the nerves and iatrogenic and traumatic injuries. Online supplemental material is available for this article. RSNA, 2016.
