Benign fibrous musculoskeletal lesions are surprisingly common, but not well understood or recognized. Their often complex clinical courses lend them an additional layer of mystery. This exhibit will: Introduce the viewer to the common benign musculoskeletal fibrous lesions as a group. What are they? Review the lesions one-by-one, including typical presenting histories and clinical courses. The focus will be on imaging characteristic (X-ray, ultrasound, CT, and MRI), centered on MRI, which is the typical end-point modality in the imaging evaluation of these lesions. Radiologic and microscopy images are sourced from our academic center. Summarize key imaging similarities and differences for these lesions. Provide the viewer with a list of take-home points so they will have familiarity when such lesions appear on their work queue. 

1. Introduction to benign fibrous musculoskeletal lesions: what are they? 2. Lesion review, including clinical context and imaging examples, with an emphasis on MRI: Extra-abdominal fibromatosis Palmar fibromatosis Plantar fibromatosis Nodular fasciitis Fibroma of the tendon sheath Elastofibroma Desmoplastic fibroma 3. Key imaging similarities and differences. 4. Take-home points: what should I remember about these lesions?
