Imaging Features of Superficial and Deep Fibromatoses in the Adult Population
Figure 11
Intraabdominal fibromatosis. Mesenteric fibromatosis: a 29-year-old female with right-sided flank pain. (a) Axial and (b) coronal CT images demonstrate a mass (arrows) in the small bowel mesentery with irregular margins and attenuation similar to skeletal muscle. The mesenteric fat surrounds the lesion outlining the extent. Retroperitoneal fibromatosis: a 12-year-old male with a mass palpated in the left lower quadrant on routine physical exam. (c) CT topogram reveals an intraabdominal soft tissue mass (arrow) displacing the descending colon (arrowheads). (d) Axial CT shows a large retroperitoneal heterogeneous lesion (arrow) causing mass effect on the left psoas muscle (curved arrow) with scattered areas of mild-to-moderate enhancement.
