Paraspinal fibromatosis with infiltrative borders. (a) Axial postcontrast T1-weighted (TR500/TE20) sequence demonstrates fibromatosis of the paraspinal muscles with prominent enhancement (asterisk) and infiltrative margin (arrows). (b) Photograph of gross specimen reveals multiple collagenized bands and irregular, spiculated margin (arrows). (c) Photomicrograph (original magnification, ×100; H-E stain) also illustrates the marginal invasion of muscle (M) by the collagenized fibromatosis lesion (F).
