Abstract
In this study is reported the case of a 63-year-old-woman with history of dyspnea, palpitations, and precordial pain who underwent cardiologic evaluation. The physical examination did not reveal abnormalities. The echocardiogram showed great mass in the left atrium, suggesting myxoma which was confirmed by tomography and catheterization. The patient underwent surgical treatment with a good postoperative evolution. The diagnosis of myxoma was confirmed by histopathologic study. In this study is included a bibliographic review and a comment emphasizing the diagnostic difficulty based on signs and symptoms, as well as the details about the development of bilateral pleural effusion possibly related to the myxoma.
Highlights
We present a case of an oligosymptomatic patient who underwent cardiological propaedeutic, which revealed a large left intra-atrial lesion
63-year-old female patient who underwent cardiological evaluation due to dyspnea during medium effort, palpitation and precordialgia
The patient did not present pre-existing diseases and did not use drugs regularly. She underwent an echocardiogram that showed a large mass in the left atrium, characterized by computed tomography as a great expansive ovoid lesion measuring 6.2 x 5.0 x 4.5 cm, and blocking a great part of the left atrial cavity with density slightly lower than the heart muscle
Summary
About 75% of them are benign, and approximately 50% are myxomas. The symptoms are atypical and highly variable. According to the size and location of tumors, the patients may present symptoms that range from asymptomatic to a presentation of lung congestion, and may present sudden death by thrombo-embolic phenomena. We present a case of an oligosymptomatic patient who underwent cardiological propaedeutic, which revealed a large left intra-atrial lesion. The patient underwent surgical resection of this lesion. The anatomic-pathological study confirmed the diagnosis of myxoma. The patient developed pleural effusion in the postoperative, possibly related to the lesion
