BACKGROUND: Vocal fold paralysis (VFP) is sometimes the only sign of chest diseases. However, some patients with VFP due to chest diseases are not diagnosed correctly at the first examination, which may leave the patients untreated for a long time. Depending on the situation, chest x-ray is not enough for detecting the primary lesion. The objective of this study was to discuss the diagnostic procedure for VFP based on the retrospective analysis of the cases.
METHODS: A total of 42 patients (29 males and 13 females) with VFP due to chest disease examined at the Department of Otolaryngology of Kyoto Prefectural University of Medicine between 1988 and 2002 were reviewed retrospectively.
RESULTS: Of the primary chest diseases, lung cancer (15 cases) was the most common, followed by thoracic aortic aneurysm (TAA) (9 cases), metastatic tumor from other regions (6 cases), pulmonary and mediastinal tuberculosis (TB) (5 cases), and esophageal cancer (4 cases). While the primary lesions were easily detected with chest x-ray in most of the cases, some lesions in the aortopulmonary window were difficult to detect. Contrast-enhanced computed tomography (CT) was useful to detect any mass in this region.
CONCLUSIONS: In the diagnosis of VFP due to chest diseases, chest x-ray was useful but not always enough for detecting the primary lesion. Necessity of further examinations including contrast-enhanced chest CT must be kept in mind for the cases with negative chest radiographs.
