[A TUBERCULOUS PSEUDO-ANEURYSM OF THE ABDOMINAL AORTA COMPLICATED BY MILIARY TUBERCULOSIS].

A 66-year-old man was transferred to our hospital on November 2010 owing to a diagnosis of miliary tuberculosis. Treatment was initially started with INH, RFP, PZA, and EB. However, PZA and EB were discontinued because of their adverse effects. Subsequently, chest radiographic and laboratory findings gradually improved. However, the patient experienced lumbago, which exacerbated towards the end of March 2011. An abdominal CT scan showed an abdominal mass at the L3-L5 level between the abdominal aorta and lumbar vertebra. On the basis of the findings of abdominal ultrasonography, MRI, and PET-CT, infectious abdominal aortic aneurysm was highly suspected. Therefore, vascular graft replacement surgery was performed at the beginning of May 2011. The result of histopathological analysis showed the presence of acid-fast bacteria in the aneurysm and the lymph nodes around it, revealing that the aneurysm was due to systemic miliary tuberculosis. After the surgery, the patient was administered LVFX in addition to INH and RFP for 18 months and showed no recurrence.
