Sonographic Features of Superficial‐Type Nodular Fasciitis in the Musculoskeletal System

Abstract

Superficial-type nodular fasciitis is often located in the deep subcutaneous fat near the muscle fascia, has a hypoechoic appearance with echogenic foci or peripheral hyperechoic nodules, and quite often does not show internal vascular flow. If a superficial soft tissue mass has the above findings, superficial-type nodular fasciitis should be included in the differential diagnosis.
