Bocio Intratorácico / Intrathoracic goiter

El bocio intratorácico se define como aquel bocio que se encuentra parcial o totalmente en el mediastino; su incidencia está en relación con el bocio multinodular. Es asintomático entre el 20­30%. Su diagnóstico se hace por pruebas de imagen; su Gold estándar es la tomografía axial computarizada. El tratamiento más efectivo y recomendado es la cirugía, sobre todo para pacientes con síntomas opresivos o con sospecha de malignidad y bocios hiperfuncionantes en quienes el tratamiento farmacológico no fue exitoso. Se detalla el caso de una paciente de 59 años de edad, quien, con síntomas opresivos esternales, a quien se le diagnostica masa mediastínica, la cual se resuelve con indicación quirúrgica, siendo resolutiva para la paciente, con mejoras en la sintomatología y diagnostico de benignidad.

Intrathoracic goiter is defined as partially or totally in the mediastinum; its incidence is related to multinodular goiter. It is asymptomatic in 20-30%. Its diagnosis is made by imaging tests; the gold standard is computerized axial tomography. Treatment can be pharmacological with risk of recurrence; the most effective and recommended is surgery, especially for patients with oppressive symptoms or with suspected malignancy. We present the case of a 59-year-old patient with sternal oppressive symptoms, who is diagnosed with a mediastinal mass, which resolved by surgery, with improvements in symptoms and a diagnosis of benignity.

Substernal Goiter: a case to remember

SUMMARY Goiter is a localized or generalized thyroid hypertrophy. It can remain within the cervical region or grow down until it invades the mediastinum. The signs and symptoms depend on the size and location of the goiter. Although drugs and radioactive iodine are often used to treat thyroid disease, the presence of symptomatic substernal goiter is a clear indication for surgery. Death or postoperative complications rarely occur. We present a case of a 71-year-old man with recurrent thyroid pathology in the form of substernal goiter and hyperthyroidism even after partial thyroidectomy. The importance of this relates to the clinical evolution, volume, and location of the goiter as well as the surgical and pharmacological approach.

RESUMO O bócio é a hipertrofia da glândula tiroide localizada ou generalizada. Esta pode localizar-se na região cervical ou crescer através do mediastino. Os sinais e sintomas dependem do tamanho e da localização do bócio. Embora os fármacos e o iodo radioativo sejam frequentemente usados para tratar doenças tireoidianas, a presença do bócio subesternal sintomático é uma clara indicação para a cirurgia. A morte ou complicações pós-operatórias são raras. Apresentamos o caso de um homem de 71 anos com recorrência de patologia tireoidiana sob a forma de bócio subesternal e hipertireoidismo após tireoidectomia parcial. A importância desse caso relaciona-se com a evolução clínica, o volume e a localização do bócio e a abordagem cirúrgica e farmacológica desse tipo de patologia.

Les goitres plongeants A propos de 230 observations

We report a retrospective study of 23 intrathoracic goiters cases. It is question of 17 mediastinocervical cases and 6 cervico-mediastinal cases. No case of pure endothoracic goiter has been found to be present. There is a clear female prevalence [77% of cases]. In more than the half cases, the patients have a goiter history for more than 10 years. As for the compression signs, the tracheal compression is prevalent since that it was seen in 2/3 of cases. All patients underwent a successful cervictomy, carried out alone. No malignant intrathoracic goiter was seen in our series. The post - operative sequelae are most often simple in patients managed at time and the best conditions
