Primary Tubercular Granulomatous Thyroiditis, Presenting as Thyroid Nodule with Hyperthyroidism, Pyrexia of Unknown Origin and Severe Anemia.

Tuberculosis of Thyroid gland is a rare entity even in countries with high prevalence of tuberculosis. The patients present with a broad spectrum of manifestations ranging from an isolated painful nodule to frank hyperthyroidism. We report an interesting case of primary tubercular granulomatous thyroiditis, presenting as a thyroid nodule with pyrexia of unknown origin, hyperthyroidism and severe anaemia which responded to anti tubercular and anti-inflammatory treatment with complete recovery, as evidenced by blood reports and CT scan reports. Thus, proper diagnosis may avoid unnecessary surgical interventions, that were a trend in the past.
