Abstract
BackgroundAmong primary cardiac tumors, atypical lipoma is very rare. In particular, cases with lipomas in both the pericardium and the atria are even rare.Case presentationWe report the case of a 49-year-old male patient presented to our department because of chest pain. Echocardiography revealed two large masses in both the pericardium and the right atrium. Then the tumors were completely resected and the histopathological examination revealed atypical lipoma. The patient recovered well without any complication and discharged from hospital.ConclusionsWe report a very rare case of a huge atypical lipomas located on the pericardium and right atrium. These tumors were easily detected by echocardiography and final diagnosed after surgical resection and pathological examination.
Highlights
Among primary cardiac tumors, atypical lipoma is very rare
Echocardiography revealed a giant mass in the pericardial cavity, and another mass in the right atrium
The pericardium was opened, a giant mass measuring 15cmx12cmx8cm was found in the pericardial cavity, another yellowish fatty mass was revealed in the right atrium (Fig. 4)
Summary
Atypical lipoma is very rare. In particular, cases with lipomas in both the pericardium and the atria are even rare. The most common malignant tumors of the heart is angiosarcoma whereas atypical lipomas represent < 1% [2, 3]. Cardiac atypical lipomas are usually found incidentally because of asymptomatic, and in most cases require treatment or surgical intervention. Echocardiography revealed a giant mass in the pericardial cavity, and another mass in the right atrium. Another echogenic mass measuring 4.8 × 3.1 cm was observed in the right atrium (Fig. 2).
