Introduction: Aortitis is seen in a wide variety of diseases. It was rarely found in the past but this is changing because of new imaging techniques. Case description: We present the case of a 45-year-old man who was found on thyroid ultrasound to have infrarenal aortitis and pathological lymphadenopathies in different locations. After an exhaustive diagnostic process, tuberculous aortitis, an infrequent manifestation of extrapulmonary tuberculosis, was diagnosed. The condition resolved after a 6-month course of antibiotics and a 6-week course of corticosteroids. Conclusion: Tuberculous aortitis is an atypical manifestation of Mycobacterium tuberculosis infection. The absence of typical symptoms and the difficulty of isolating the microorganism makes its diagnosis difficult. Therefore, clinical suspicion, microbiological tests and imaging are key for reaching the diagnosis and starting treatment for a serious disease that can cause aortic aneurysm and dissection.
