Intravascular epithelioid hemangioendothelioma (EHE) is a rare endothelial tumor with an intermediate grade of malignancy. We present a case of one woman affected by EHE of the femoral vein. Contrast-enhanced ultrasonography played a role in diagnosing EHE and helped differentiate it from thrombosis. To our knowledge, this is the first reported contrast-enhanced ultrasonography of intravascular EHE in the imaging literature.
A 46-year-old woman presented to our hospital due to pain and swelling in her right lower limb since 5 years prior to her presentation.
The patient was misdiagnosed as having thrombosis by ultrasound. Contrast-enhanced ultrasonography showed solid lesions with visible blood supply, suggesting angiogenic tumors.
The patient was treated by complete surgical removal of the mass and postoperative radiotherapy. Pathological examination confirmed the diagnosis of EHE.
During follow-up, there were no signs of local or distant relapse.
Intravenous EHE may be misdiagnosed as thrombosis by ultrasound and contrast-enhanced ultrasonography can help make the differential diagnosis.
血管内上皮样血管内皮瘤（EHE）是一种罕见的内皮肿瘤，恶性程度为中度。我们报告一例女性股静脉EHE病例。超声造影在EHE诊断中发挥了作用，并有助于将其与血栓形成相鉴别。据我们所知，这是影像学文献中首次报道的血管内EHE的超声造影检查。
一名46岁女性因右下肢自就诊前5年起出现疼痛和肿胀前来我院就诊。
患者最初被超声误诊为血栓形成。超声造影显示实性病变并有可见血供，提示血管生成性肿瘤。
患者接受了肿块完整切除手术及术后放疗。病理检查确诊为EHE。
随访期间，无局部或远处复发迹象。
静脉EHE可能被超声误诊为血栓形成，而超声造影有助于进行鉴别诊断。
