Overview
- Intravenous leiomyomatosis (IVLM) is characterized by the extension into venous channels of histologically benign smooth muscle tumor arising from either the wall of a vessel or from a uterine leiomyoma.
- Fewer than 100 cases have been reported in all, and only 14 cases involved intracardiac extension from the IVC.
- In one reported case, this slowly growing invasive neoplasm extended not only into the heart but into both pulmonary arteries as well. [1]
Pathophysiology
- The etiology of intravenous leiomyomatosis is unclear. All described patients are female, and most are white, premenopausal, and parous.
- Intravenous leiomyomatosis should be considered in young women with cardiac symptoms who have a right atrial mass as well as a pelvic mass or who have previously undergone hysterectomy for leiomyoma uterus with intravenous involvement.
Differentiating Intravenous Leiomyomatosis from other Diseases
- Intravenous leiomyomatosis must be differentiated from other diseases such as:
- Renal malignancies
- Sarcoma
- Thrombosis of the intravenous catheter
Epidemiology and Demographics
- The median age is 45 years, with patients ranging from 26 to 70 years old.
- Female are affected with Intravenous leiomyomatosis.
Natural History, Complications and Prognosis
- Common complications of Intravenous leiomyomatosis include embolization, recurrence of tumor, and metastasis.
- The tumor is slow growing, and the prognosis is favorable.
Diagnosis
Symptoms
- The patients may be asymptomatic or have symptoms of uterine leiomyomas, syncopal episodes, dyspnea on exertion, shortness of breath
