- To review the updated classification of fibroblastic and myofibroblastic tumors.
- To analyze the main features of imaging of these lesions.
- To highlight some important tips when making a differential diagnosis between these neoplasms and other non-tumoral entities.
Soft tissue tumors of fibrous origin are among the most common tumors found in clinical practice. Depending on the type, they may have different biological behavior and imaging appearance. Some of these lesions may be reactive to a primary process (elastofibroma dorsi and myositis ossificans).
The quantity and distribution of cellular and myxoid matrix of each tumor are depicted on MR imaging. Tumors with high cellularity tend to show higher signal intensity (SI) on T2-weighted imaging (WI) and more enhancement. In contrast, tumors with dense internal collagen content show low signal intensity (SI) and less enhancement.
