Fig. 1C —19-year-old male with Gardner syndrome and massive desmoid tumor of paraspinal musculature. Sagittal unenhanced T1-weighted MR image (618/14, B) and contrast-enhanced T1-weighted image (804/14, C) show lack of enhancement of hypointense bands (arrows) in A. These nonenhancing, hypointense bands are probably areas of fibrosis within enhancing active fibroblasts. Patients with Gardner syndrome or familial adenomatous polyposis have 20% lifetime risk of extraabdominal or, more commonly, intraabdominal desmoid tumor.
