“…Of the remaining 38 reports, all have orthotopic thyroid glands which could be distinguished from “ectopic thyroid.” A summary of the clinical details of the 38 ITT patients are shown in Table I . 1 , 2 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 …”

Objective/Hypothesis To examine the clinical features of benign intratracheal thyroid (ITT) and their management strategies and outcomes. Study Design Case series study. Methods This systemic review was conducted in two international academic centers. This review includes 43 patients: one new case from the Massachusetts Eye and Ear Infirmary, four new cases from Beijing Tongren Hospital, and 38 previously published cases. We analyzed these 43 cases and summarized the patients' epidemiological data, clinical features, and treatment regimens. Results ITTs were less common in men than in women (male:female ratio of 3:10). ITT was observed in patients as young as neonates and as old as 85 years. Orthotopic thyroid nodules were present in 55.8% of the patients with ITT. Malignancy was incidentally found in 4.6% of all ITTs. Imaging examinations showed that the ITTs were typically attached to the posterolateral/lateral tracheal wall of the first, second, or third tracheal rings. Tissue attachment between the ITT and normal thyroid lobes was seen in 59.5% of the patients. Thirty‐seven patients underwent surgery: 30 underwent open surgery, and seven underwent endoscopic debulking resections. One neonate received thyroid suppression therapy. One patient with ITT and papillary thyroid cancer was treated with radiotherapy and ultimately died after recurrence. Conclusions Surgical resection is an effective treatment for benign ITT. We hypothesized that abnormalities during the embryonic development of Berry's ligament might play a role in ITT pathogenesis. Level of Evidence NA Laryngoscope, 131:E2609–E2617, 2021

The large airways can be affected by a wide spectrum of acquired benign and malignant diseases. These lesions may present as focal or diffuse processes and with narrowing or widening of the airway. Some of these may be asymptomatic for quite some time and may be incidentally detected on imaging, while others may be symptomatic, causing airway compromise. There may be a characteristic radiograph and computed tomography (CT) appearance, suggesting a narrow differential. When the imaging findings are not definitive, tissue may be obtained for pathological analysis. It behooves the radiologist to be familiar with the pathologic findings that correlate with the radiographic or CT appearance of the most frequently seen large airway lesions. In this way, we may improve our diagnostic accuracy. This paper will present the imaging findings of the most prevalent tracheobronchial lesions along with any associated pathology.Teaching Points• The large airways can be affected by many acquired benign and malignant diseases.• Large airway lesions may present as focal or diffuse processes, with narrowing or widening.• There may or may not be characteristic imaging appearance of large airway disease.• If imaging findings are not definitive, tissue may be obtained for pathological analysis.

During embryonic development, the abnormal migration of thyroid tissue may cause ectopic localization of the gland in the intralaryngotracheal space. This case report describes the management of a young patient with a recent diagnosis of asthma. During bronchoscopy, a large mass occupying the tracheal lumen was discovered. After tracheotomy to protect the airway, an incisional biopsy was performed and revealed an intratracheal ectopic thyroid. The deep incisions through the tracheotomy to the base of the lesion allowed colloidal content to leak out of the mass until complete resolution of airway obstruction. Fifteen days later the patient was released totally rehabilitated.
