Why the study?
Leiomyosarcomas of the inferior vena cava are uncommon malignancies with limited research detailing optimal diagnostic and clinical management.
This report provides clinical insights into the radiologic evaluation and transvenous biopsy techniques for rare inferior vena cava leiomyosarcomas.
Supports feasibility of dual transvenous biopsy approaches in rare IVC leiomyosarcoma; leaves open need for validation in larger series.
Leiomyosarcomas of the inferior vena cava (IVC) are uncommon malignancies. There is limited research detailing optimal diagnostic and clinical management. Here, we present 2 unique cases of IVC leiomyosarcoma including one in which the mass was partially ruptured through the vessel at initial presentation. We detail radiologic findings, 2 different transvenous approaches for biopsy of these masses, and subsequent oncological management.
