Right Atrial Paraganglioma: An Extremely Rare Primary Cardiac Neoplasm Mimicking Myxoma.

ABSTRACT: In this report, we present a case of 35-year-old lady who had presented with atypical chest pain and exertional breathlessness for past six months. Transthoracic and transesophageal echocardiograms showed a well-circumscribed, echo-dense mass in the right atrium, attached to the interatrial septum at the level of atrioventricular junction and in the vicinity of coronary sinus ostium. She underwent successful resection of the cardiac mass. Histopathology revealed paraganglioma, which was reconfirmed by immunohistochemistry study. This represents an extremely rare presentation as primary cardiac tumors are 20-times less common than metastatic tumors and paraganglioma is one of the rarest primary cardiac tumors, accounting for < 1% of all cases.

Right atrial myxoma mimicking tricuspid stenosis.

Project description:A 62-year-old man presented to the cardiology clinic with symptoms of fatigue, shortness of breath and swelling in the abdomen and legs. A pedunculated mobile mass with a short stalk in the right atrium was found to originate from the inferior vena caval opening and prolapse into the right ventricle through a tricuspid valve during diastole in echocardiography. The patient was referred to our department and surgery was planned for right atrial myxomas diagnosis. The mass with surrounding tissue was surgically removed using the cardiopulmonary bypass method. No postoperative complications were seen in the currently asymptomatic patient who is still under our follow-up schedule.

Hydatid cyst of the pericardium mimicking a right atrial myxoma.

Project description:The hydatid cyst of the pericardium is a rare pathology; its clinical presentation is variable. It can reveal straightaway at the stage of life-threatening complications. Only a few cases of isolated pericardial hydatid cysts have been reported. Echocardiography, computed tomography, and magnetic resonance imaging are important diagnostic tools for the diagnosis of echinococcosis, and surgery remains the treatment of choice. Herein, we report a rare case of pericardial hydatid cyst who presented to our emergency department with complaints of palpitations, chest pain, and shortness of breath.

Right Atrial Myxoma with Coexistent Coronary Artery Disease - A Rare Combination.

Project description:Atrial myxomas are the most common primary heart tumors. Two-dimensional echocardiography is the diagnostic procedure of choice. The majority of myxomas are located in the left atrium. Myxoma in the right atrium is an uncommon location. The co-occurrence of right atrial myxoma with atherosclerotic coronary artery disease (CAD) is uncommon. In our case, right atrial myxoma was associated with CAD, which makes it a unique case because very few cases of right atrial myxoma coexistent with CAD are described in literature.

Right atrial myxoma: Unusual location; uncommon association.

Project description:We are presenting a case of the right atrial myxoma found in a case of rheumatic heart disease. During transthoracic echocardiography for the evaluation of a suspected rheumatic valvular heart disease, a diagnosis of severe mitral stenosis with severe mitral regurgitation with the right atrial thrombus was made. On transesophageal echocardiography, a pedunculated mass in the right atrium was confirmed. In the course of surgery, it was found that there is a tumor originating from the right atrial appendage (RAA) which was confused with clot on echocardiography. Rheumatic heart disease and myxomas have different etiopathogenesis, and this coexistence has not been reported. Further, right atrial myxoma arising out of RAA is also being reported for the first time.

Cardiac magnetic resonance imaging and a rare case of an atrial myxoma causing an atrial septal defect.

Project description:A 40 year-old athletic woman presented with worsening dyspnea on exertion over the preceding several months. Chest radiograph showed borderline cardiomegaly and subsequent echocardiography demonstrated a 5.0-cm left atrial mass as well as left-to-right interatrial shunting through a patent foramen ovale. Cardiac magnetic resonance imaging was performed, which demonstrated signal characteristics consistent with an atrial myxoma. The patient then underwent urgent surgical treatment with good technical and clinical outcome. Histologic examination confirmed an atrial myxoma. Cardiac magnetic resonance imaging was valuable in characterizing the nature of the atrial mass and patent foramen ovale, helping guide the surgical approach.

Surgical management of a giant right atrial myxoma.

Project description:Cardiac tumours represent around 0.2% of tumours overall, and primary cardiac tumours are even more uncommon. We report the case of a 72-year-old female with a 7 cm × 4 cm right atrial mass which was prolapsing through the tricuspid valve. The mass was resected and histological analysis confirmed a myxoma. This report describes a rare finding of a giant right atrial mxyoma and subsequent surgical management.

Right atrial thrombus mimicking myxoma with pulmonary embolism in a patient with systemic lupus erythematosus and secondary antiphospholipid syndrome.

Project description:Antiphospholipid syndrome is a well-defined entity that is characterized by spontaneous abortion, thrombocytopenia, and recurrent arterial and venous thromboses. A partially calcified right atrial thrombus mimicking myxoma with recurrent pulmonary embolism has not been previously reported in a patient who also had systemic lupus erythematosus and secondary antiphospholipid syndrome. Herein, we describe the case of a 37-year-old woman with systemic lupus erythematosus and secondary antiphospholipid syndrome who was admitted to the hospital with progressive exertional dyspnea. Ventilation-perfusion scanning showed multiple parenchymal defects in the lungs that portended pulmonary embolism. In addition, the scanning revealed normal regional ventilation. Transthoracic and transesophageal echocardiography showed a right atrial mass that was highly suggestive of myxoma, and the patient subsequently underwent surgery. A histologic examination showed an organized, partially calcified thrombus. Intracardiac thrombus has been rarely reported as a complication of antiphospholipid syndrome. In our patient, the preoperative investigations could not differentiate the partially calcified right atrial thrombus from a myxoma, and the diagnosis was made postoperatively.
