case_images: Sagittal T1-weighted MR images before and after intravenous contrast administration. Axial T2-weighted image. Paraspinal mass (arrows) at three months postoperatively interpreted as a postoperative seroma. Retrospectively, the presence of a barium sulfate filament (curved arrows) was noted as a hypointense curvilinear wire.

case_images: MR imaging showed a well-defined rounded lesion in the paraspinal muscles in the surgical bed (Figure 1).
case_images: Sagittal T1-weighted MR images before and after intravenous contrast administration. Axial T2-weighted image. Paraspinal mass (arrows) at fourteen months postoperatively. Center of the mass has become hypointense on T2 and the enhancing peripheral wall has thickened. The discovery of a barium sulfate filament (curved arrows) was the characteristic finding to evocate the diagnosis of gossypiboma.

case_images: Additionally, the presence of a intralesional curvilinear low signal structure was noted, prompting the possibility of a gossypiboma from a retained surgical gauze (Figure 2), confirmed on a subsequent radiograph (Figure 3).
case_images: Lateral and frontal radiograph showing the contorted barium sulfate filament confirming the presence of a surgical gauze in the paraspinal soft tissues.
