Cardiac varix is a rare entity. It is generally small and is in relation to the interatrial septum, often mistaken as cardiac myxoma. A 19-year-old girl, on evaluation of respiratory infection, was found to have a mass compressing the right atrium. Computed tomographic scan and magnetic resonance imaging suggested a differential diagnosis of pericardial cyst or hydatid cyst. Peroperatively, a large (8 x 6.5 x 5.5 cm) cystic lesion in relation to the right atrial free wall was found. The histopathology of the resected mass revealed it to be a cardiac varix. The case is notable for its large size and its location in relation to the right atrial free wall.

However, in this case, a large cardiac varix (80 × 65 × 55 mm) was found in relation to the right atrial free wall, presenting as a mass compressing the right atrium [5]. Rasmussen et al. [6] reported that a cardiac varix supplied by atrial branches of both the right and left coronary arteries made it more likely that the lesion was an arteriovenous malformation rather than a venous varicosity.

    ABSTRACT: A 73-year old man underwent transthoracic and transoesophageal echocardiography and computed tomography, which revealed what appeared to be an asymptomatic primary mobile tumour located in the right atrium. During surgery, the mass was found to be associated with the right atrial septum and was subsequently resected. Histopathology of the mass revealed a cardiac varix with phleboliths. The patient had an uneventful postoperative course and no signs of recurrence at the 10-month follow-up. © The Author 2012.

    • "Secondary tumors can reach the heart through the inferior vena cava and invade the right atrium as solid masses, such as renal and hepatocellular carcinoma, uterine leiomyoma or Wilms tumors [1]. Among right atrial masses, right atrial cysts are rare and may represent hydatid, blood, bronchogenic cysts, cardiac varices or right coronary artery aneurysms [1,9,10]. Based on the appearance and location of the right atrial cysts, echocardiography helps in the differential diagnosis as follows: "

    ABSTRACT: A 71-year-old woman presented with a right adnexal solid mass invading the right gonadal vein and inferior vena cava up to the hepatic veins revealed by CT and confirmed by MRI. A thin-walled cyst and a solid mass were unexpectedly found in the right atrium by transesophageal echocardiography (TEE) in the operating room. Using color Doppler and air bubbles as contrast material a circumscribed cyst was confirmed and localized close to the IVC. The cyst was connected to the mass in the inferior vena cava. The tumor, including the cyst, was removed without using cardiopulmonary bypass and described as a low-grade endometrial stromal sarcoma, a rare slowly growing tumor. This is the first TEE description of endometrial stromal sarcoma manifesting as a right atrial cyst.

    ABSTRACT: A 68-year-old female patient was referred for the evaluation of an incidentally detected asymptomatic cardiac mass. Imaging studies showed a 3.0 x 2.4 cm, well circumscribed, round, cystic mass with a calcified nodule that was attached to the lower rim of the fossa ovalis in the right atrium. Under cardiopulmonary bypass, the right atrium was opened to reveal a well circumscribed, dark bluish, pedunculated mass. Histologically, the specimen was a unilocular cyst lined by flattened endothelium, with peripheral fibrin clots and dystrophic calcification of the wall. Immunohistochemical staining of the lining cells was positive for cluster designation 34, which represents hematopoietic progenitor cell antigen. The final pathologic diagnosis was compatible with varix of the heart, which should be considered for a cystic mass with a calcified nodule located in the right atrium, near the lower rim of the fossa ovalis.
