Benign metastasizing leiomyoma with intracaval leiomyomatosis.

Abstract

We present an unusual case of benign metastasizing leiomyoma in association with intracaval leiomyomatosis. To our knowledge, this is the first reported case of metastasizing leiomyoma with coexistent intravenous leiomyomatosis (IVL). Magnetic resonance imaging is useful for the diagnosis of pelvic and caval IVL.
