Computed tomography (CT) showed the collapse of L5, and magnetic resonance imaging (MRI) further demonstrated decreased signal intensity in the L3, 4, 5 vertebral bodies on T1-weighted images, intermediate signal intensity on T2-weighted images, and increased signal intensity on T2 STIR images (Figure 1).
An abdominal CT showed about a 6 cm hematoma in the retroperitoneal space (arrow).

An abdominal CT showed approximately 6 cm hematoma in left retroperitoneal space (Figure 2).
(a) Angiogram revealed a pseudoaneurysm of left fourth lumbar artery (white arrow). (b) The pseudoaneurysm was treated with transcatheter placement of microcoils into the left fourth lumbar artery (black arrow).

Moreover, angiography revealed left fourth lumbar artery pseudoaneurysm (Figure 3(a)). The pseudoaneurysm was treated with transcatheter placement of microcoils (VORTEX, GDC, Boston-Scientific Japan) into left fourth lumbar artery (Figure 3(b)).
