Abstract


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.
