RESUMEN
RATIONALE: Cardiac lymphangioma is a rare disease. Until now, there have been only a few cases of cardiac lymphangioma reported in the literature. PATIENT CONCERNS: We report the case of a 57-year-old female patient with cardiac lymphangioma from atrial septum. DIAGNOSIS: Color Doppler echocardiography was performed, which revealed a tumor occupying a large amount of space in the left and right atrium. INTERVENTIONS: The patient underwent thoracoscopic cardiac tumor resection under general anesthesia according to the procedure used for benign tumors. OUTCOMES: The patient recovered completely and was discharged home. Follow-up color Doppler echocardiography scans obtained from 6 months to 2 years after the operation showed no recurrent mass. LESSONS: Once the tumor is detected, surgical treatment should be implemented as soon as possible.
