“…The CE of the anechoic region in the cardiac myxoma indicated that it had vascular properties, with pathology confirmation, which is different from the previous view that the anechoic region in the cardiac myxoma is the cystic degeneration of the tumor. 3 Cardiac myxoma originates from the multipotent mesenchymal stem cells of the endocardium, with the ability to differentiate into endothelial cells and myocardial cells, 4 and the function of angiogenesis and the potential of high vascularization, which manifests as a hypervascular tumor and needs to be distinguished from cardiac malignancies.…”

Cardiac myxoma is the most common primary benign cardiac tumors, mostly found in the left atrium. It was previously reported that the main component of myxoma was myxoid stroma riched in acid‐mucopolysaccharide, the blood vessels in which were sparsely distributed, being characterized as hypovascular tumor by contrast echocardiography (CE) and computed tomography angiography (CTA). There are few reports of myxoma with rich blood supply and we report one in the left atrium.

Background Cystic myxomas are quite rare. Moreover, few reports have evaluated the causes that constituted them. Case summary A 73-year-old Asian man presented for preoperative examination of osteoarthritis, and transthoracic echocardiography (TTE) revealed an incidental intracardiac mass. Therefore, he was referred to our department for further evaluation. He had no specific symptoms or family history. The TTE showed a 32 × 24 mm spherical mass adherent to the left atrial septum. The upper part of the mass was cystic in formation with hypoechoic inside and resembled a light bulb. The transesophageal echocardiography showed the feeding arteries flowing from the bottom into the cystic part. In addition, two jet strips drained from the cystic part in the direction of the mitral valve. Coronary angiography (CAG) revealed the feeding arteries, which consisted mainly of the right coronary artery conus branch and the left circumflex branch, and the blood flowed into the saccular area from the feeding arteries and excreted toward the mitral valve. Surgical resection was performed due to the mobility, and the histopathology confirmed cystic myxoma. Discussion We described the unique anatomical formation of a cystic myxoma, which consisted of an exquisite balance between the tumor-feeding arteries and draining outlet vessels.

“…Typically, these tumors are solid, round, or polypoid in shape and attached to the interatrial septum, lacking a cystic structure. However, cystic myxomas are exceedingly rare (3)(4)(5)(6)(7)(8). Intracardiac blood cysts are another unusual cardiac tumor, mainly seen in fetuses or infants under six months of age and rarely reported in adults.…”

BackgroundPrimary cardiac tumors are uncommon, with the majority being benign myxomas. Cystic myxoma, a particularly rare type of benign cardiac tumor, demands cautious differential diagnosis from other cardiac tumors.Case summaryA 43-year-old male patient presenting with intermittent dyspnea was referred to our department for surgical evaluation. Transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) unveiled an intra-left atrial cyst, which was subsequently found to be blood-filled during a video-assisted microinvasive heart surgery. Pathological examination depicted a cyst wall filled with small stellate and fat spindle cells, along with a mucoid matrix, indicating a diagnosis of cystic myxoma.ConclusionsWe herein presented a rare case of an adult patient with cystic myxoma, initially misdiagnosed as an intracardiac blood cyst (CBC) prior to surgery, and ultimately verified via pathological findings.
