Multi Modality Imaging Features of Cardiac Myxoma

Abstract

Primary cardiac neoplasms are rare entities of which approximately 75% are benign and the remaining 25% malignant. Myxomas are the most common benign primary cardiac tumor (30%) and most commonly arise in the left atrium from the interatrial septum at the fossa ovalis. However, they also can originate in any cardiac chamber. Clinical presentation and patient symptomatology are determined by size, location, and mobility of the myxoma. This review will discuss the clinical presentation, natural history, pathology, and multimodality imaging features of cardiac myxomas.

Left Atrial “Tumor Blush” Supplied by the Right Coronary Artery

“… 5) On computed tomography and echocardiography, myxomas appear as a spherical mass with heterogenous attenuation or echogenicity, and occasional specked foci of internal calcifications. 2) However, the presence of a calcified peripheral rim, such as seen in our case, is rarely described. Coronary angiogram is not part of the routine preoperative assessment, and its utility should be evaluated based on patients-specific factors.…”

“…Myxomas account for 30%–50% of benign primary cardiac tumors and usually affect middle-aged women. 1) They are most often found in the left atrium (75%), 2) in which case, neovascularization typically originates from the left coronary artery. 3) Unusual locations include the right ventricle, 4) the left atrial appendage 5) and attachment to the coumadin ridge.…”

Global Transient Amnesia as the Predominant Symptom of Cardiac Myxoma: A Case Report

“…The primary imaging modality for cardiac myxomas is the echo-cardiogram. Myxomas present on the endocardial surface as spherical masses with speckled echogenic foci [ 11 ]. MRI provides a more detailed, accurate evaluation to narrow down the diagnosis when assessing for cardiac myxomas.…”

“…Areas of calcification are echogenic on imaging. This can be distinguished from typical cardiac myxomas, which have a heterogeneous appearance due to the different types of tissues present [ 11 ].…”

Calcificação Caseosa do Anel Mitral: Diagnóstico Pós-Transplante Cardíaco

“…Os diagnósticos diferenciais mais importantes incluem mixoma cardíaco, geralmente móvel, pedunculado e localizado ao longo do septo interatrial, abscessos e pseudoaneurismas, cujo conteúdo, embora pastoso, carece de depósitos de cálcio e tumor amorfo cardíaco calcificado, uma lesão constituída por tecido fibroso colagenoso denso com nódulos de cálcio, sem constituinte pastoso. [9][10][11][12][13] A abordagem terapêutica, em geral conservadora, é pautada pelas implicações clínicas. Em pacientes com insuficiência mitral, a cirurgia cardíaca é indicada.…”
