Clinical, pathological and radiological features of paraspinal textiloma: report of two cases and review of the literature.

Textiloma is a term used for retained cottonoid or surgical sponge in the operation field. Although they occur mostly after thoracic or abdominal operation, they can also be encountered after surgery of extremities or the spine. There are few reports of spinal cases in which MR and CT imaging findings of textilomas have been described. In this report, two additional cases with MR, CT and pathological features of paraspinal textilomas are described. CT image demonstrated a paraspinal mass simulating a malignant tumour. While T1-weighted MR images showed the masses with low signal intensity, T2-weighted MR images showed heterogeneous masses with low and high signal intensities.
