Intravascular Leiomyomatosis with Extension to Right Atrium: A Case Report

Intravascular leiomyomatosis is an infrequent benign neoplastic disorder characterized by the proliferation of smooth muscle cells within the venous system, often extending from the iliac or gonadal veins into the inferior vena cava. In rare instances, it may infiltrate cardiac cavities or pulmonary vasculature, manifesting as intracardiac leiomyomatosis.
