Thyroid tuberculosis is a rare entity. The clinical symptomatology is non-specific with a picture of goiter or thyroiditis with a subacute or chronic evolution. We report an observation of thyroid tuberculosis in a 39 year old female patient presenting with a nodular thyroid goiter without general manifestations. The diagnosis was confirmed by anatomopathological examination of the total thyroidectomy specimen. Antituberculosis treatment was initiated for six months with a favorable clinical course.
