总结腹壁型侵袭性纤维瘤病的超声图像与临床特征，提高临床及超声医师对该疾病的认识。

回顾性分析2018年1月至2025年11月于北京协和医院就诊并经病理确诊为腹壁型侵袭性纤维瘤病的10例患者的超声图像，总结超声图像特征。

10例腹壁侵袭性纤维瘤病患者年龄29~64岁，中位年龄34.5岁；女性患者9例，男性患者1例。10例患者均为单发病灶，且均发生于腹壁肌层。超声表现：低回声为主（10/10例，100%），沿肌层平行生长（10/10例，100%），沿肌层水平方向浸润性生长（7/10例，70%），在垂直于肌层的方向上病灶边界清晰（10/10例，100%），内部回声不均匀（9/10例，90%），内部未见钙化及液性暗区（10/10例，100%）。

腹壁型侵袭性纤维瘤病在超声图像上有一定的特征性表现，超声医师应结合临床表现及超声特征与其他腹壁占位加以鉴别。

To summarize the ultrasound images and clinical features of aggressive fibromatosis of the abdominal wall, and to improve the understanding of the disease by clinicians and sonographers.

The ultrasound images of 10 patients with aggressive fibromatosis of the abdominal wall diagnosed by pathology in Peking Union Medical College Hospital from January 2018 to November 2025 were retrospectively analyzed, and the characteristics of ultrasound images were summarized.

The ages of the 10 patients with aggressive fibromatosis of the abdominal wall ranged from 29 to 64 years (median age 34.5 years), including 9 female patients and 1 male patient. All 10 patients had single lesions and all occurred in the muscular layer of the abdominal wall. The ultrasound manifestations were mainly hypoechoic (10/10 cases, 100%), parallel growth along the muscular layer (10/10 cases, 100%), infiltrative growth along the horizontal direction of the muscular layer (7/10 cases, 70%), clear lesion boundaries in the direction perpendicular to the muscular layer (10/10 cases, 100%), and uneven internal echoes (9/10 cases, 90%). No calcification or liquid dark areas were observed internally (10/10 cases, 100%).

Aggressive fibromatosis of the abdominal wall has certain characteristics on ultrasound images. Sonographers should combine clinical manifestations and ultrasound characteristics to distinguish it from other masses of the abdominal wall.
