Uterine leiomyoma is a commom disease in women, however, intravenous leiomyomatosis of uterine origin extending via inferior vena cava into the right side of the heart,known as intracardiac leiomyomatosis is a rare condition (3%). In 1907, Durk reported the first case of intracardiac extension.
The patient was a Woman, 35 years old, admitted to our emergency department for an intracardiac mass. She had shortness of breath,fatigue and chest pain. The transthoracic two dimensional echocardiography showed an echogenic oval mass mobile in right atrium and projected through right ventricle in diastole. This mass was observed to extend from inferior vena cava to the right atrium. The echotransesophageal three dimensional showed a large mobile mass that extended from inferior vena cava to the right atrium. A Computer tomographic (CT) scan showed a hypodense multilobulated mass in the pelvis, which had invaded the inferior vena cava and right atrium. The patient underwent a two stages surgery. In first stage (transatrial tumor resection). The operation was performed normal temperature with establisment of cardiopulmonary bypass (CPB). Subsequently, the pathological report was confirmed uterin smooth muscle origin. The second stage surgery ( total histerectomy) was done four weeks later for removing lobulated mass uterin with dimensions 20x15x7.5cm with confirmed histopathological of leiomyoma.
Because of it is nonspecific clinical presentation and rarity, an intracardiac Leiomyomatosis continues to be a misdiagnosed as either thrombus or myxoma. The cardiac imaging techniques like a transthoracic echocardiography 2d and transesophageal echocardiography 3d have been used to define the presence, extension of tumor as appearance of the mass and involvement of adjacent structures.
