A 56-year-old woman was initially seen in March 1998 with a complaint of back pain. Her thyroid gland was swollen and the level of TSH was elevated at 10 microU/ml. Chronic thyroiditis with hypothyroidism was diagnosed. Negative reactions were obtained for both anti-thyroglobulin and anti-thyroid peroxidase antibodies. Daily treatment with thyroxine 50 mg was started. A cough developed in August 1998, and her chest radiographs revealed multiple bilateral consolidation shadows. A transbronchial lung biopsy specimen demonstrated mononuclear cells infiltration in the alveolar septa with fibrosis, consistent with nonspecific interstitial pneumonia (NSIP). There were no findings clinically or serologically suggestive of collagen-vascular diseases. Ultimately interstitial pneumonia compatible with the NSIP pattern in association with chronic thyroiditis was diagnosed. Oral prednisolone (30 mg/day) and azathioprine (50 mg/day) administration was initiated. The cough and the shadows on the chest radiographs improved. However, one year after completion of the treatment, interstitial pneumonia recurred. Retreatment with prednisolone and azathioprine has resulted in its improvement.

We report a case of a mediastinal mass indenting the left lateral tracheal wall of a 35-year-old male who presented with weight loss, cough and breathlessness. Flow volume loop and thyroid function tests were normal and thyroid peroxidase antibodies were negative. Technetium scintigraphy and positron emission tomography both showed no uptake. Endobronchial ultrasound-guided fine needle aspiration confirmed ectopic mediastinal thyroid tissue. Mediastinal ectopic thyroid tissue is very rare. Most patients are asymptomatic and euthyroid with positive signals on scintigraphy. False negative technetium scintigraphy can occur in areas of necrosis, carcinoma and from substernal tissue. Ectopic thyroid tissue is a rare but important differential diagnosis when investigating mediastinal lesions and should be considered even if scintigraphy is negative in the right clinical context. Endobronchial ultrasound-guided fine needle aspiration can be used when scintigraphy is not diagnostic.
