UNASSIGNED: BACKGROUND @entity20866 ( @entity20866 ) is a rare @entity5 , which is usually of uterine origin, characterized by intravascular nodular masses of histologically benign smooth muscle that may extend variable distances, including into the inferior vena cava, right atrium and pulmonary arteries. @entity5 may arise from uterine @entity2909 , walls of the uterine vessel, or myometrium. It usually occurs at between 20-70 years of age with a median age of 45 years. The most commonly affected @entity1 are pre-menopausal and multiparous. Intra-cardiac extension may represent a diagnostic challenge as it is usually misdiagnosed as a right @entity4615 and may cause multiple symptoms, such as @entity1353 , @entity591 , @entity662 , @entity1163 , and even death. CASE REPORT We present the case of a 40-year-old female @entity1 with past medical history of arterial @entity101 , who was referred to a @entity65 due to an intra-cardiac mass found on 2D echocardiogram. The @entity1 was given the rare diagnosis of @entity20866 of the uterus with extension into the gonadal veins, inferior vena cava, right atrium, right ventricle, and main pulmonary arteries. Imaging workup including trans-esophageal echocardiogram, cardiac catheterization, contrast-enhanced abdomen and pelvic CT scans, and cardiac MRI was performed for evaluation. CONCLUSIONS @entity20866 is a rare diagnosis that merits consideration in a young pre-menopausal female @entity1 with cardiac symptoms associated with a right atrial mass. Radiologists play a vital role in the diagnosis and follow-up of @entity1 with the diagnosis of @entity20866 . Differential diagnosis includes @entity455 as well as primary and @entity3 . Early detection is imperative for appropriate treatment and surgical planning.
