Subsequently, spinal magnetic resonance imaging (MRI) with Gadolinium injection revealed left paraspinal muscular enhancement and multiple intramuscular fluid collections with thick enhancing wall [Figures 1 and 2].

Subsequently, spinal magnetic resonance imaging (MRI) with Gadolinium injection revealed left paraspinal muscular enhancement and multiple intramuscular fluid collections with thick enhancing wall [Figures 1 and 2].
Axial, T1-weighted MR images with Gadolinium injection showing two necrotic collections (asterisks) within the left paraspinal muscles with thick enhancing walls (black arrows) extending to the spinal canal in form of septated collection (white arrow)

There was also intraspinal extension from the fourth lumbar (L4) to the first sacral vertebrae (S1) with epidural enhancement and epidural abscess measuring 10 mm occupying the left half of the spinal canal and displacing the dural sac to the right [Figure 3].
