Sagittal T1 pre (A) and post contrast (B),  sagittal T2 (C) and Axial T1 post contrast (D) MRI images of the cervical spine demonstrating a large posterior fluid collection with an obvious sinus tract inferiorly and associated gas bubbles. This was proved to be a post-operative seroma and epidural scar (note the thick rind of enhancement) that was partially accounting for this patient's residual and worsening symptoms despite the initial decompressive surgery.
