Atypical cardiac myxomas are rare occurrences and may present with a variety of clinical manifestations depending on the location and morphology. A 46-year-old woman had a 4 x 3 x 2-cm myxoma originating from the superior wall of the left atrium, found by echocardiography and multislice tomography. The tumor was successfully treated by surgical excision. The resected tumor was a well-defined encapsulated mass with a narrow-base stalk originating from the right wall of the left atrium in between the right upper and lower pulmonary vein. The patient recovered without complication and was discharged 6 days after the operation. At 1-year follow-up, echocardiography revealed normal cardiac function without reccurence in terms of mass. Although up to 80% of myxomas are localized in the left atrium, of which 75% involve in the interatrial septum, it should not be forgotten that myxomas can appear in an atypical localization, as occurred in our case.References
