A rare cause of dyspnea: Left atrial myxoma mimicking pulmonary embolism

Primer kardiyak tümörler nadir olup miksomalar bu nadir tümörlerin en sık görülen tipidir. Miksomaların yaklaşık %75i kalbin sol atriyumunda görülür ve genellikle kalbi üst iki odacığa bölen (interatriyal septum) duvardan başlar. Genellikle iyi huyludurlar. Bazen asemptomatik seyrederler, bazen ise nonspesifik klinik semptomlar gösterebilirler. Nonspesifik semptomlar nedeniyle özellikle ilk evrelerde erken tanı zor olabilir. Miksomaların en sık semptom ve bulguları nefes darlığı, paroksismal noktürnal dispne, pulmoner ödem, öksürük, hemoptizi, ödem ve halsizliktir. Bu yazıda, belirgin kalp yetersizliği semptomları olan pulmoner emboliyi taklit eden sol atriyal miksoması olan 76 yaşında bayan olguyu sunduk.

Dispnenin nadir bir nedeni: Pulmoner emboliyi taklit eden solatriyal miksoma

Primary cardiac tumors are rare. Myxomas are the most common type of these rare tumors. About 75% of myxomas occur in the left atrium of the heart usually beginning in the wall (interatriyal septum) that divides the two upper chambers of the heart. They are usually benign in nature. Some of them may remain asymptomatic but sometimes may exhibit a variety of non- spesific clinical symptoms. Because of nonspecific symptoms, early diagnosis may be difficult, particularly in the early stages. The common signs and symptoms of myxomas are shortness of breath, orthopnea, paroxysmal nocturnal dyspnea, pulmonary edema, cough, hemoptysis, edema and fatigue. In this report, we presented a case of a 76-year-old woman with profound heart failure symptoms, and left atrial myxoma mimicking pulmonary embolism.
