A 61-year-old woman presented with intermittent low back pain that persisted for past one month. The pain worsened within one week and became unbearable. Three months previously, the patient was admitted to a local hospital for productive cough. Lung CT showed suspicious TB lesions, and T-SPOT was positive. After excluding other diseases, the local hospital started diagnostic anti-tuberculosis treatment consisting of HRZE. The patient took the medication irregularly because of gastrointestinal reaction. A physical examination revealed no abnormalities. Laboratory results were white blood cells, 7.22x109/L; hemoglobin, 122 g/L; platelets, 216 x109/L; CRP, 32.97 mg/dl; and procalcitonin, 0.213ng/mL. The sputum GeneXpert test result was positive and sensitive to rifampicin. Multiple infections and diffuse miliary nodules in both lungs suggested tuberculosis. Thoracic and abdominal aortic CTA examination showed a 51x28 mm2 pseudoaneurysm arising from the lower abdominal aorta, surrounded by a patchy shadow and lymphadenopathy (Figure 5). Combined with the patient's medical history, tuberculous aortic pseudoaneurysm was considered. Emergency digital subtraction angiography was performed after admission, and two coated stents were implanted in the abdominal aorta and iliac artery. Angiography showed that the stents were well- positioned, blood flow was smooth, and a pseudoaneurysm did not develop. The patient was discharged from the hospital 2 days post-operation and received anti-tuberculosis drug treatment, including isoniazid 0.6 g once daily, rifapentine 0.45 g twice a week, ethambutol 0.75 g once daily, pyrazinamide 0.5 g three times daily, and moxifloxacin 0.4 g once daily. Abdominal aortic CTA performed two weeks later revealed that the aneurysm did not recur (Figure 6). Our follow-up plan was consistent with that of the patient in case 1. The patient tolerated the anti-tuberculosis drugs well.
