Diagnostic Pathway From Incidental Mass to Metastatic Melanoma: Role of Multimodal Imaging and Medical Therapy

Case Report: A rare diffuse mitral valvular myxoma

Cardiac myxoma is a common benign tumor, however, myxoma extensively distributed on the mitral valve is rare and seldom reported. A patient who presented with exertional dyspnea and chest tightness was examined by transthoracic and transesophageal echocardiography successively. Multiple neoplasms on the mitral valve with moderate mitral regurgitation were found and were further proved to be a diffuse myxoma on the mitral valve by histology. Three-dimensional transesophageal echocardiography provided a precise evaluation of the mitral valve neoplasms, contributing to clinical decision-making.

Case Report: A myxoma with a far reach

A 73-year-old woman presented to the emergency department with a syncopal episode and a history of dizzy spells. A transthoracic echocardiogram demonstrated a large left atrial mass extending into the right upper pulmonary veins. Subsequently, cardiac magnetic resonance imaging and coronary computed tomography angiography with three-dimensional reconstruction and printing of the heart and mass were performed, which demonstrated a high index of suspicion for an atypical left atrial myxoma. The mass was excised robotically, and the pathology report confirmed a diagnosis of myxoma.
