[Clinical signs and correlation with radiological extent in a series of 117 retrosternal goitre].
OBJECTIVE
To report, compare the clinical signs and the radiological signs of retrosternal goitre (cervico-thoracic goitre) and try to establish a correlation between clinical signs and radiological extent.


METHODS
One hundred and seventeen patients with a goitre beyond the sub-clavian vessels in cervico-thoracic CT-scan and with a benign histopathology examination after thyroid surgery in the head and neck department, University Hospital, Amiens, France between February 1997 and January 2004 were included in this retrospective study. The initial clinical assessment includes the respiratory and swallowing functional signs, palpable mass and mobility of the vocal cords. A correlation is analyzed between the extent of the goitre, the anatomic relations with the trachea and oesophagus and clinical signs.


RESULTS
Dyspnea is the commonest of the functional signs (39.3%) for young subjects (p < 0.05), due to tracheal compression regardless of the side of extension of the goitre. Dysphagia (16.2%) is not correlated with the extent of the goitre in this series. A cervical palpable mass is present in 69.2% of cases.


CONCLUSIONS
The cervico-thoracic CT-scan is the key examination of the assessment of a retrosternal goitre making it possible to appreciate its features, its anatomic relations and its tracheal involvement sometimes announced by respiratory disorders, the presence of a dysphagia should alert to the possibility of posterior extension which can not be felt during the cervical palpation.
