Thyroid tuberculosis mimics cancer on grayscale sonography and elastography

Abstract

Tuberculosis of the thyroid gland is an extremely rare disease. It can be misdiagnosed as thyroid cancer, thyroiditis, or multinodular goiter. Here we describe one case of thyroid tuberculosis with contralateral cervical lymphadenopathy mimicking a thyroid cancer on conventional sonograms and elastograms. A 60‐year‐old woman presented to our hospital with swollen lymph nodes in the right neck for 2 years. There was no history of weight loss, fever, or hemoptysis. Her complete blood count was normal and the erythrocyte sedimentation rate was as high as 63.8 mm for the first hour. Thyroid function test and chest examination were within normal limits. Ultrasound examination of the thyroid showed a hypoechoic nodule (0.7 cm × 0.7 cm) in the left lobe, which was poorly demarcated from the rest of the thyroid. Color Doppler image showed mild internal vascularity. Real‐time elastography showed the mass to appear homogenously blue, ie, firm (Figure ). Cervical ultrasound examination showed multiple hypoechoic swollen lymph nodes in the right neck. The patient accepted surgical treatment and the left thyroid lobe and swollen lymph nodes were removed. Subsequent histologic examination revealed necrotizing epithelioid granulomas with Langhans giant cells (Figure ). Elastogram shows the tuberculosis mass (arrows) appearing
