[Autonomous intrathoracic goiter. Apropos of 2 new cases].

An autonomous intrathoracic goiter (AIG) is a thyroid gland formation located in the thorax or, more precisely, the mediastinum. It is not a metastasis of thyroid cancer, and it has no parenchymatous or vascular connections with the cervical thyroid gland. It is fed by thoracic vessels and is observed in the absence of previous thyroidectomy. Its multiple appellations, and the fact that clinical reports often lack precision and detail, complicate investigations concerning AIG, a rare variety of mediastinal goitre (slightly more than 100 cases published). AIG is essentially caused by an abnormal embryonic development of the thyroid gland. It must be distinguished from migratory goitres partially resected and forgotten in the thorax after cervicotomy. This fully mediastinal tumour is usually removed by the thoracic approach.

Cerebrovascular circulation "steal" syndrome secondary to a voluminous retrotracheal goiter.

A case of recurrent transient ischaemic attacks in the brain resolved after removal of a voluminous retrotracheal goiter is presented. The presence of congenital atretic left vertebral artery, associated with impairment of left carotid artery blood flow by a very large inferior thyroid artery, probably caused the episodes to transient ischaemic attack.

Current concepts in computerized tomography of the mediastinum.

Computed tomography (CT) has dramatically changed the imaging approach to the mediastinum. CT can depict precise cross-sectional mediastinal anatomic detail defining fat, water, and near muscle density tissues. Not only diagnosis but staging of some disease processes is now possible. The key to understanding the mediastinum is a sound knowledge of normal mediastinal anatomy and the potential disease processes which may affect the mediastinum. Normal CT mediastinal anatomy is illustrated and discussed. Pathological processes involving the thymus, lymphatics, endocrine systems, and great vessels are emphasized describing their clinical presentations, appearance, and the techniques of examination.

[Cervico-mediastinal goiter. Problems of surgical technic and tactics].

The Authors, on the basis of their experience, as well as of the data of the literature, discuss the problems of technique and tactics involved in the treatment of retrosternal goiters. As to the way of approach, they think cervicotomy should be primarily preferred, and the complementary sternotomy should be associated to the former only in some limited cases of totally dipped and large-sized goiter. They, moreover, assert that, beyond the diagnostical and therapeutical difficulties, endothoracic goiter, if adequately treated, keeps a favourable diagnosis, not dissimilar from the one of cervical goiters.
