RESUMO
The mediastinum constitutes an area of special surgical interest due to important anatomical relationships and histopathologic variability of mediastinal primary and metastatic tumours. Mediastinum was considered inaccessible until the end of the 19th century. For many decades the diagnosis of mediastinal disease relied solely upon clinical presentation, and the mainstay of treatment was medical therapy. The advancements in radiology and intraoperative ventilatory support facilitated the improvement of certain diagnostic and therapeutic approaches to mediastinal disease.
RESUMO
INTRODUCTION: Myxomas are the most common benign tumors of the heart. They vary widely in size, and little is known about their growth rate. The present case report is, we believe the first in bibliography that provides images of an apical left ventricular myxoma from transthoracic echocardiography and computed tomography scans taken a year apart. CASE PRESENTATION: We present the rare case of a 65-year-old asymptomatic Caucasian man with an apical left ventricular myxoma that grew over a 12-month period. Our patient underwent successful surgical excision of the tumor and had an uneventful postsurgical recovery period. CONCLUSIONS: Left ventricular myxomas are benign and curable tumors. They do not usually present with systemic symptomatology and most of them are diagnosed as sequelae of syncope caused by left ventricular outflow tract obstruction or systemic embolization. Because they are usually removed after diagnosis, the growth rate of myxomas is generally unknown. We present a rare case of the asymptomatic presentation of a left ventricular myxoma and its documented growth during a 12-month period.
