Nodular Fasciitis in the Finger: The Sonographic Findings and a Literature Review

ABSTRACT

A 39-year-old woman presented with a rapidly growing nodule on the right thumb. An ultrasound study demonstrated a mass located in the deep subcutaneous tissue on the ulnar side of the interphalangeal joint. Incisional biopsy yielded the diagnosis of nodular fasciitis. We discuss the ultrasound appearance of nodular fasciitis as reported in the literature and how to make the differential diagnosis of an echogenic finger mass.
