Summary: | Abstract
Background
Nodular fasciitis (NF) has nonspecific clinical manifestations and is often misdiagnosed as sarcoma. The investigations of imaging methods for NF were limited.
Objective
To analyze the ultrasound (US) features of NF, and to evaluate the diagnostic value of US for NF.
Materials and Methods
A total of 61 NF patients were recruited retrospectively, and 551 lesions in the subcutaneous fat layer were included for comparison. We evaluated the ultrasound features of the patients and divided the NF cases into three types. Chi‐square test or Fisher exact test were conducted to detect the potential difference in the distributions of three types in the two groups.
Results
Among the 61 NF cases, 65.6% were in the upper extremities (
n
= 40). The proportion of type 1, 2, and 3 were 57.4%, 24.6%, and 18.0%, respectively. NF were significantly more likely locating in the upper extremities than the other soft tissue tumors (
p
< 0.001). Type 1 and type 2 of sonographic features were significantly more commonly observed in NF than other soft tissue tumors among the three types (
p
< 0.001).
Conclusion
The type 1 and type 2 of US features can help to distinguish NF from other lesions. US has great potential to improve the diagnostic accuracy and reduce the unnecessary surgery. |
