1. To illustrate the spectrum of solitary fibrous tumors in a variety of anatomic sites. 2. To review various relevant cross-sectional imaging techniques with pathologic correlation which aid in diagnosis.

This presentation will start with discussion of pathological findings. Although solitary fibrous tumors (SFTs) were previously thought to occur most commonly in the pleura, it can originate any site of the body. We evaluate CT and MR imaging findings of SFTs in a variety of anatomic sites including meninges, maxillary sinus, orbit, pleura, breast, abdominal wall, mesentery, para-spinal, retroperitoneum, spermatic cord, prostate and several soft tissue regions (cutis, subcutaneous fat, and muscle), including both benign and malignant SFTs. They have variable signal intensity on T2-weighted imaging according to amount of collagen stroma, myxoid stroma, and cellularity. However, they also show some characteristic findings such as “well-defined and lobulated” morphology, “flow void”, “chocolate chip cookie appearance” and the “black-and-white mixed pattern”. Radiologists must know that SFTs have variable imaging features and biological behavior and be aware of tumor characteristics in order to suggest the diagnosis.
