Non-enhanced CT scan on 13 October 2021. (A) Lateral CT scan showed T11-L1 with bone destruction and sequestrums (thin arrow). (B) Axial CT scan showed paravertebral abscess (thick arrow) was indistinguishable from the thoracic aorta (arrowhead).

T11-L1, which was obvious in T12, mild reduction in the height of the vertebral body and narrowing of T11-12 intervertebral space, with a cold paravertebral abscess on both sides (Figure 1). These results were consistent with spinal tuberculosis.
An enhanced MRI scan on 6 November 2021 showed a pseudoaneurysm measuring 5.7 x 3.7 x 5.8 cm. (A) (T2WI), (B) (T1WI): Sagittal MRI scan showed T11-L1 with bone destruction (arrowhead). Large cold abscess in the front of the vertebral body with flow void signal (thick arrow). (C) T2WI axial MRI scan showed a cold abscess with flow void signal (thick arrow) located posterior to the thoracic aorta (arrowhead). (D) Axial enhanced MRI scan showed the pseudoaneurysm (thick arrow) located posterior to the thoracic aorta (arrowhead) was hyperintense.

Obvious enhancement was observed after the lesion was enhanced (Figure 2), which was indicative of a thoracic aortic pseudoaneurysm.
An enhanced CT scan on 1 December 2021 showed a pseudoaneurysm measuring 8.2 x 5.2 x 22.9 cm. (A,B) Axial and lateral enhanced CT scan showed the thoracic aorta communicated with the pseudoaneurysm through the rupture (arrowhead). (C) Coronal enhanced CT scan showed the pseudoaneurysm significantly enlarged into the left iliac fossa (thick arrow) compared with Enhanced MRI scan on 6 November 2021.

FEU.A CT scan revealed enlargement of pseudoaneurysm (Figure 3). Following this, the patient underwent endovascular aneurysm repair.
A timeline showed the progress of the disease and the patient's treatment and follow-up.

Because the follow-up was outpatient, no laboratory examinations were done (Figure 4).
