Abstract

Vocal fold paralysis (VFP) can happen in various conditions due to mediastinal LADs, however no study has proposed anthracosis as an etiology. Here we discussed the chest CT features of anthracosis related LADs causing VFP. Among 41 cases of pulmonary anthracosis, 10 had VFP that all were presented with hoarseness. The paralysis was unilateral (left side) in all cases. Extra-nodal infiltration and conglomeration of lymph nodes were significantly higher in patients with paralysis. Left paratracheal, pre-vascular, and aortopulmonary window lymph nodes were seen in all patients. We propose that mediastinal LADs secondary to anthracosis could be a reason for left side VFP. © 2021 The Voice Foundation
