Imaging of the mediastinum: applications for thoracic surgery

A Multidisciplinary Surgical Approach to Mediastinal Masses in Children

The aim of this study is to demonstrate the safety and advantages of a multidisciplinary approach to surgical resection of mediastinal masses in children. Eight patients underwent resection of a mediastinal mass by a team involving both a pediatric general surgeon and pediatric cardiothoracic surgeon. One patient required rapid initiation of cardiopulmonary bypass to complete the tumor resection and repair an aortic injury that occurred when removing adherent tumor from the structure. Perioperative outcomes were excellent for all patients. This series shows that a multidisciplinary surgical approach can be potentially life saving.

Imaging of anterior mediastinal tumours

Anterior mediastinal tumours include primary and secondary tumours. Patients may be asymptomatic or present with symptoms related to local tumour invasion or systemic symptoms due to release of hormones/cytokines or antibodies. The most common symptoms at presentation include chest pain, dyspnoea, cough, fever and chills. Despite rapid developments in imaging techniques, accurate staging of anterior mediastinal tumours remains a diagnostic quandary. Multimodality imaging plays an important role in determining surgical resectability and/or impact on subsequent management. This article briefly discusses the epidemiology and incidence of anterior mediastinal tumours and describes the role of imaging in tumour characterization and staging in detail. We focus on the more commonly encountered anterior mediastinal tumours.

Acute respiratory distress secondary to posterior mediastinal goiter: a case report

Large posterior mediastinal goiters are extremely rare. Progressive enlargement and possible compression of adjacent structures, as well as malignant potential necessitate that these goiters should be surgically excised. A review of mediastinal tumors, specifically intra-thoracic goiters is presented along with a case report of acute respiratory compromise secondary to tracheal compression by a large posterior goiter.
