Objective:

To investigate the clinical features and ultrasound manifestations of aggressive fibromatosis (AF) in order to improve the recognize of AF and the ability of ultrasound diagnosis.

Methods:

The clinical and ultrasonic data of 20 patients with AF confirmed by pathology were retrospectively analyzed

and the clinical features and ultrasound characteristics of AF were summarized.

Results:

The 20 lesions in 20 patients in this materia

l

all of which were solitary

of which 17 were the first lesions and 3 were recurrent lesions

and the recurrent time was 0.3-1.5 years; There were 10 cases of abdominal wall type

8 cases of external abdominal type and 2 cases of intra-abdominal type

and there were 13 females

7 males

aged from 21 to 66 years old

median age 33 years old

of which 10 patients (50.0%) had previous surgery history. The size of the lesions varies

with the largest diameter being about 1.0-23.2 cm and the median diameter being 5.3 cm.The ultrasonic characteristics showed the shape regular and irregular has 9 cases (45.0%) and 11 cases (55.0%) respectively; there were 18 cases (90.0%) and 2 cases (10.0%) expressed as expansive growth and invasive growth respectively; 5 cases with clear boundary (25.0%) and 15 cases with unclear boundary (75.0%); 20 cases with solid internal structure (100.0%) and hypoechoic internal echo (100.0%); the posterior echo performance enhancement 7 cases (35.0%)

without change 12 cases (60.0%)

and attenuation 1 case (5.0%); the internal blood flow Alder grade 1 was 5 cases (25.0%)

grade 2 was 8 cases (40.0%) and grade 3 was 7 cases (35.0%).

Conclusion:

The clinical features and ultrasonic manifestations of AF have certain characteristics

combination of the two is great value for the accurate diagnosis of AF.
