Tc-99m pertechnetate scintigraphy before and after potassium perchlorate administration for the diagnosis of retrosternal goiter.

A 52-year-old woman was hospitalized because of dyspnea and dysphagia. Thoracic computed tomography revealed a retrotracheal mass. Tc-99m pertechnetate scintigraphy showed intense accumulation of radioactivity corresponding to the mediastinal mass detected by computed tomography. Repeated Tc-99m pertechnetate scintigraphy performed after oral administration of potassium perchlorate (KCLO4) revealed complete disappearance of the radioactive accumulation in the mediastinum, suggesting that the retrotracheal mass was a retrosternal goiter. Subsequent surgical removal and analysis of the mass showed it was indeed a retrosternal goiter. This case highlights the importance of Tc-99m pertechnetate thyroid scintigraphy with and without KCLO4 administration as a simple, accurate, and cost-effective imaging method to diagnose retrosternal goiter.

Acute respiratory failure and tracheal obstruction in patients with intrathoracic goiter.

Four cases of acute life-threatening tracheal obstruction due to intrathoracic goiter are reported. Acute respiratory insufficiency caused by an upper airway obstruction in patients with intrathoracic goiter is exceptional. In 3 of 4 cases reported, the histologic study showed multiple foci of recent hemorrhage, the mechanism probably responsible for these episodes.

Diagnosis of posterior mediastinal goiter by computed tomography.

Although radionuclide examinations are usually diagnostic for evaluating mediastinal goiters, false negative examinations do occur, and the diagnosis may not be suspected based on clinical or radiographic features. In such a setting, computed tomography (CT) may demonstrate both anatomic and physiologic evidence of thyroid mass, providing useful diagnostic information. We report a case in which CT derived data aided in an early diagnosis of mediastinal gioter.

Use of the laryngeal mask for fibrescope-aided tracheal intubation in an awake patient with a deviated larynx.

I report a case in which fibrescope-aided awake tracheal intubation was achieved using a laryngeal mask, in a patient with a mediastinal goitre in whom tracheal intubation with both a laryngoscope and a fibreoptic bronchoscope had failed. The tumour extended to the upper part of the mediastinum. The larynx and the upper segment of the trachea were displaced by the tumour. Awake tracheal intubation with both a laryngoscope and a fibreoptic bronchoscope failed. The laryngeal mask was then inserted without difficulty. After a fibreoptic bronchoscope had been covered by a plastic tube, the combination was passed through the laryngeal mask into the trachea. The fibreoptic bronchoscope and the laryngeal mask were removed, and a reinforced endotracheal tube was then inserted over the plastic tube into the trachea. The time for tracheal intubation was about 70 s. The laryngeal mask may allow easier location of the laryngeal inlet with a fibreoptic bronchoscope, and this technique is a useful alternative to the conventional technique of tracheal intubation in the patient with a deviated larynx.

Fatal haematemesis due to benign retrosternal goitre.

The development of a goitre in the retrosternal space may result in many different symptoms due to local compression. We describe a case in which such a goitre resulted in full-thickness ulceration of the oesophagus, which presented as a fatal haematemesis. We believe that such a complication has not been previously reported.
