The images demonstrated extensive hyperdensity within the spinal canal subarachnoid space related to extravasation of contrast material, which was not previously observed on the outside hospital imaging [Figure 1].

The imaging suggested that the contrast material extravasated out of the bladder into the extraperitoneal space [Figure 2].
Coronal (a and b) and axial (c) CT scans of the lumbosacral spine demonstrating extensive fracturing of the left sacral pelvic tube, with violation of left sacral nerve roots, allowing contrast to enter the subarachnoid space at the left sacral ala predominantly through the left L5 and S1 nerve roots

Because of extensive fracturing of the left sacral pelvic tube with violation of the left sacral nerve roots, the contrast agent entered the subarachnoid space at the left sacral ala predominantly through the left L5 and S1 nerve roots [Figure 3].
