[Intrathoracic goitre--undiagnosed--nevertheless operated]. / Intratorakální struma--nediagnostikovaná--prece odoperovaná.

A case review of a female patient, who was indicated for surgery for a goitre with minor bilateral retrosternal spread. The procedure included bilateral thyroidectomy during which the surgeon noticed unusual intrathoracic pathology in the left hemithorax, under the removed lobe. Postoperative chest x-ray and CT examinations revealed intrathoracic goitre, which was then removed during a following procedure. In the article, the authors discuss this uncommon pathology. Because of its uncommon location, the pathology was not detected on standard preoperative endocrinological examination. It was the follow up, postoperative examination, based on which the correct treatment was initiated.
