Large left atrial myxoma with synchronous laryngeal squamous cell carcinoma: A case report

Figure 1 Imaging findings. A-D: Neck computed tomography (CT) showed a malignant tumor (arrowhead) involving the supraglottic larynx. Positron emission tomography (PET)/CT showed high (18)F-fluorodeoxyglucose (FDG) uptake by the laryngeal tumor; E and F: Chest CT showed a 3.8 cm × 2.2 cm hypodensity (arrow) in the left atrium, which had faint (18)FDG uptake on PET/CT; G and H: Transthoracic echocardiogram showed a large, well circumscribed heterogenous lesion (arrow) in the left atrium, protruding through the mitral valve opening causing mitral inflow obstruction, transmitral peak pressure gradient and mean pressure gradient measured 17 mmHg and 6 mmHg, respectively.
