	Introduction

 
True primary mediastinal ectopic goiters are very rarely seen, accounting for fewer than 1% of all goiters.¹ They originate from ectopic thyroid tissue located in the mediastinum, without any connection with the cervical thyroid gland. Here we discuss the case of a patient with a lung nodule and mediastinal mass with associated bronchial abnormality.

	Clinical Summary

 
Mediastinal enlargement and a solitary pulmonary nodule were detected on a 68-year-old male patient's chest radiograph during routine annual examination. Computed tomography and magnetic resonance imaging revealed a lobulated, solid, and well-demarcated right paratracheal mass 6 x 4 x 4 cm in dimension ( Figure 1).

Right tracheal bronchus (bronchus suis) was observed on bronchoscopy. Results of bronchoscopy and bronchial lavage cytologic examination were not diagnostic. Positron emission tomography (PET)–computed tomography revealed metabolic activity both in the parenchymal mass (standard uptake values 8.3 early and . . . [Full Text of this Article]
