Abstract

Cardiac myxoma is a common benign primary intracardiac tumor in the general population, and it is generally characterized as a benign tumor, and the morbidity of biatrial myxoma is low. Cases of biatrial myxoma in young patients are extremely rare. Furthermore, severe complications of cardiac myxoma, such as cerebral embolism, can have fatal consequences. Imaging can effectively assist in making a correct diagnosis and a safe and efficient surgical treatment plan. In this case report, we describe a unique case of a young woman who presented with biatrial myxoma accompanied by pulmonary embolism and cerebral embolism. Computed tomography pulmonary angiography (CTPA) detected multiple filling defects in the bilateral cardiac and bilateral inferior pulmonary artery basal branches. Transthoracic echocardiography (TTE) revealed irregular isoechoic masses in the bilateral atrium. Postoperative histopathology confirmed a biatrial myxoma. The patient was discharged on the ninth day after surgery.

Highlights

Cardiac myxoma is a common benign primary intracardiac tumor with an incidence rate of 0.0017% [1]
Transthoracic echocardiography (TTE) revealed irregular iso-echoic masses in the bilateral atrium that were likely myxomas, given their location and appearance in a young patient; the myxoma in the left atrium measured approximately 38 × 21 mm, and it was attached to the junction of the lower part of the interatrial septum (IAS) and the root of the anterior mitral leaflet; in the right atrium it measured approximately 51 × 27 mm, and it was attached to the lower part of the IAS (Figure 2A)
We present the case of a 17-year-old girl with biatrial myxoma, which is a rare, surgically correctable underlying cause of stroke and acute pulmonary embolism in a young patient

Summary

INTRODUCTION

Cardiac myxoma is a common benign primary intracardiac tumor with an incidence rate of 0.0017% [1]. We describe a rare biatrial myxoma complicated by pulmonary embolism and cerebral embolism, and review its clinical and imaging characteristics reported in previous cases These characteristics help clinicians and radiologists pay attention to this disease and can effectively assist in establishing accurate diagnosis and developing a safe and efficient surgical treatment plan. Transthoracic echocardiography (TTE) revealed irregular iso-echoic masses in the bilateral atrium that were likely myxomas, given their location and appearance in a young patient; the myxoma in the left atrium measured approximately 38 × 21 mm, and it was attached to the junction of the lower part of the interatrial septum (IAS) and the root of the anterior mitral leaflet; in the right atrium it measured approximately 51 × 27 mm, and it was attached to the lower part of the IAS (Figure 2A). The patient has been followed-up postoperatively for over 2.5 months, and limb motor function of the patient has recovered to some degree, but there is intellectual and cognitive decline
