“…Four per- cent of patients with unilateral vocal cord paralysis present thyroid disease, but only 0.7% are benign. Locally invasive thyroid cancers must be correctly evaluated by imaging methods, considering that the laryngotracheal invasion justifies the RLN involvement with subsequent vocal cord paralysis (11) . Advanced malignant esophageal tumors may extend towards the tracheoesophageal groove, the RLN pathway (12) .…”

Paralisia das pregas vocais é causa frequente de rouquidão, podendo ser secundária a várias lesões ao longo do trajeto do X par craniano e seus ramos, particularmente os nervos laríngeos recorrentes. Apesar de grande parte dos casos ser idiopática, os métodos de imagem são muito importantes na pesquisa de fatores etiológicos, tais como lesões neoplásicas da tireoide e esôfago com invasão secundária dos nervos laríngeos recorrentes. Além destas, outras anormalidades como aneurismas do arco aórtico e da artéria subclávia direita podem ser encontradas. É fundamental que o radiologista conheça a anatomia pertinente a esta região e as principais afecções que podem ocorrer, para que o estudo seja corretamente planejado, auxiliando o diagnóstico e o planejamento terapêutico. Além disso, como até 35% dos casos de paralisia da prega vocal são assintomáticos, o conhecimento dos sinais radiológicos que indicam esta condição é indispensável, cabendo ao radiologista alertar o médico assistente sobre os achados do exame. Neste trabalho realizamos uma revisão da anatomia e das principais doenças responsáveis pela paralisia de cordas vocais, demonstrando-as por meio de estudos de tomografia computadorizada e ressonância magnética de casos típicos. Mostramos, também, as alterações radiológicas próprias da laringe que indicam a presença de paralisia das pregas vocais.

Airway invasion is a life-threatening complication of thyroid cancer. An important issue that deserves better attention is the differentiation between the clinical features of tracheal wall invasion versus those of an obstructive endotracheal lesion. We present information on the clinical course, diagnostic modalities utilized, management instituted, along with the prognosis, and follow-up data on a group of patients presenting with obstructive endotracheal lesions of thyroid cancer. Two thousand four hundred and eighty-nine thyroid cancer patients were seen at our institution from December 1975 to May 2000. Thirteen patients presented with symptoms of respiratory distress related to obstructive endotracheal lesions. At presentation, 11 patients underwent endoscopic examination. Imaging studies consisting of I123 whole body scan (WBS), computed tomography/magnetic resonance imaging (CT/MRI) of neck and chest, whole body positron emission tomography using 18-fluoro-2-deoxy-D-glucose ((FDG)PET) were done, as also was determination of the tumour markers, serum thyroglobulin (TG) and calcitonin. Patients were followed for one to 108 months after the initial presentation. Intraluminal tracheal obstruction was severe in eight patients; five had near-total-occlusion. Paralysis of the vocal folds was present in five. Evidence of metastatic disease was present in most patients. Dissociation between iodine uptake and TG synthesis was evident in five patients during follow-up. Four patients died of cancer. Of the nine living patients; cancer persisted in six, recurred in two patients, and remitted in one. This study has identified obstructive endotracheal lesion of thyroid cancer as a distinct entity apart from tracheal wall disease. These data provide evidence that intraluminal tracheal invasion of thyroid cancer is an ominous sign and a frequent cause of morbidity.
