Tuberculous Infection of Thyroid Gland: A Case Report

Abstract

Introduction. Tuberculosis is one of the leading causes of morbidity and mortality and almost one-third of the world is infected with this disease. Tuberculosis has been reported in many parts of the human body. But thyroid gland involvement is extremely rare and its true incidence is unknown. Case Presentation. We present the case of a 26-year-old woman who presented with a thyroid cyst which turned out to be a primary mycobacterium tuberculosis infection. Conclusion. The correct diagnosis of thyroid tuberculosis is important because of the availability of medical treatment and the limited role of surgery.

Primary tuberculosis of the thyroid gland: an unexpected cause of thyrotoxicosis

“…The preferred radiopharmaceutical agent is iodine-123 but technetium-99m sodium pertechnetate is a suitable alternative with lower radiation exposure. FNAC under ultrasound guidance and histopathological examination are the gold standard investigations16 with AFB staining and TB culture of pus or tissue in cases where the index of suspicion is high. The hallmark histological features are caseating epithelioid cell granulomas (which are specific for TB infection) and Langhans giant cells 17.…”
