Intravascular fasciitis (IVF) is a very rare disease that is difficult to diagnose preoperatively. Frequently, it can be misdiagnosed as a malignancy or deep vein thrombosis. A 26-year-old man presented with a 6-month history of intermittent cramping pain in the right calf. Duplex ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography were performed in various hospitals. The work-up revealed a hypermetabolic mass in the femoral vein, suggestive of a malignancy, such as leiomyosarcoma. The tumor was located inside the femoral vein with no invasion, and the mass was resected en bloc with the vein wall. Intraoperative frozen section biopsy revealed no malignancy, and the final pathological diagnosis was IVF. Herein, we report a case of IVF and discuss the role of imaging studies in its preoperative diagnosis, with an extensive literature review.
血管内筋膜炎（IVF）是一种非常罕见的疾病，术前难以诊断。它常常被误诊为恶性肿瘤或深静脉血栓形成。一名26岁男性，右小腿出现间歇性绞痛6个月。多家医院进行了双功超声、计算机断层扫描、磁共振成像和正电子发射断层扫描。检查发现股静脉有一个高代谢肿块，提示为恶性肿瘤，如平滑肌肉瘤。肿瘤位于股静脉内，无浸润，肿块与静脉壁一并整块切除。术中冰冻切片活检未发现恶性肿瘤，最终病理诊断为IVF。在此，我们报告一例IVF病例，并结合广泛的文献综述讨论影像学检查在其术前诊断中的作用。
