Abstract

Abstract : Objectives: To retrospectively characterize the ultrasound appearance of palmar fibromatosis in patients with a surgical or clinical diagnosis of palmar fibromatosis. Methods: A search of ultrasound reports from 2005 to 2015 and a subsequent search of medical records were performed to identify patients with a surgical or clinical diagnosis of palmar fibromatosis. The ultrasound images were retrospectively reviewed to record the lesion location, size, echogenicity, compressibility, hyperemia, and calcification. Results: A total of 36 patients were identified (average age, 60 years; 61% male), yielding a total of 55 palmar fibromatosis lesions, of which 2%, 7%, 29%, 36%, 20%, and 5% were located at the first, second, third, fourth, and fifth digits and between the fourth and fifth digits, respectively. The lesions were located directly superficial to the flexor tendons in 93% with their epicenters at the distal metacarpal in 89%. Average lesion dimensions were 13.1 mm in length, 6.8 mm in width, and 2.5 mm in depth. On ultrasound images, the lesions were characteristically hypoechoic (98%) and noncompressible (95%). Atypical features included calcification (2%), compressibility (5%), hyperemia on color Doppler images (6%), epicenters at the metacarpophalangeal joint (7%) or proximal phalanx (4%), and location superficial but lateral to the flexor tendons (7%). Conclusions: Palmar fibromatosis most commonly appears hypoechoic and is located directly superficial to the flexor tendons with an epicenter at the distal metacarpal, most commonly the fourth digit. However, the epicenter location may be at the distal metacarpal and proximal phalanx of other digits, adjacent to the flexor tendons, with possible hyperemia and calcification.
