Intravascular fasciitis (IF) is a benign, reactive, myofibroblastic proliferation that originates from the superficial or deep fascia of small / medium-sized arteries and veins.
An 8-year-old male patient was admitted to a health center with the complaint of swelling in the inguinal region. Lower extremity venous Doppler ultrasonography showed deep vein thrombosis (DVT) of the femoral vein and anticoagulation with low-molecular weight heparin (LMWH) was initiated. The patient was referred to our center for follow-up. The D-dimer level was detected within normal limits. Doppler ultrasonography was repeated and showed an intraluminal expanding mass lesion with increasing vascularity, without distinct borders and LMWH was discontinued. This lesion at the sapheno-femoral junction was excised surgically and the histopathological examination revealed intravascular fasciitis.
Clinicians should be aware that the clinical findings of IF may mimic sarcoma and thrombosis.
血管内筋膜炎（IF）是一种良性、反应性、肌纤维母细胞增生，起源于小/中动脉和静脉的浅/深筋膜。
一名 8 岁男性患者因腹股沟肿胀到健康中心就诊。下肢静脉多普勒超声显示股静脉深静脉血栓形成（DVT），开始使用低分子肝素（LMWH）抗凝。患者转至我院进行随访。D-二聚体水平在正常范围内。重复多普勒超声检查显示腔内扩张性肿块病变，血管增多，边界不明显，停用 LMWH。在股隐静脉交界处行手术切除该病变，组织病理学检查显示血管内筋膜炎。
临床医生应注意 IF 的临床表现可能类似于肉瘤和血栓形成。
