The clinical manifestations mainly depend on the size of the tumour. They usually vary from asymptomatic, mild non-specific symptoms, to severe obstructive cardiac and systemic findings. We describe herein a significantly large left atrial myxoma in a patient misdiagnosed with respiratory asthma.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>A 54-year-old lady, was diagnosed previously with asthma, presented with a history of dyspnoea on exertion, palpitations, and mild peripheral oedema. Chest X-ray suggested pulmonary congestion. Due to high suspicion of cardiac issues, transthoracic echocardiography was done revealing giant left atrial mass. Consequently, the mass was approached and excised surgically through the inverted T biatrial incision. Grossly, the mass measured 10 \u00d7 8 \u00d7 6\u2009cm, and it had a smooth surface and was filled with gelatinous material. The histopathology confirmed benign myxoma without malignant features.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Our article mainly focuses on the diagnostic challenges of a patient with atrial myxoma. The major discrepancy between the tumour size and the severity of the patient\u2019s symptoms should draw physicians\u2019 attention to consider atrial myxoma over a long list of differentials, in order to take immediate action to reduce the mortality and improve the overall prognosis.<\/jats:p>\n
