Five Cases of Deep Vein Thrombosis Caused by Iliac Vein Compression due to Intrapelvic Tumor

Abstract

We report five cases of deep vein thrombosis caused by iliac vein compression due to intrapelvic tumor. All of such patients consulted our hospital with a chief complaint of swelling of their lower extremities. Ultrasonography and computed tomography imaging revealed deep vein thrombosis and intrapelvic tumor. These tumors were diagnosed as metastatic cancer, malignant lymphoma, ovarian cancer, and ovarian cyst. We should consider the intrapelvic tumor in the differential diagnosis of the swollen legs.
