Right atrial tumor revealing intravascular leiomyomatosis: about a case and literature review

Intravascular leiomyomatosis (IVL) is a very rare extension of uterine leiomyoma through the pelvic vessels. It is a benign pathology with malignant potential with a possibility of intra-cardiac extension and metastases (cerebral, pulmonary, lymph node); early diagnosis is very difficult. Prognosis depends on involvement of the inferior vena cava and extension to the right cavities. We report a case of complications of IVL, precisely the extension in the right atrium, in a 49-year-old woman. The objective of our work is to highlight the importance of imaging in the diagnosis of the vascular extension of leimyomatosis.
