Incidental discovery of right ventricular lipoma in a young female associated with ventricular hyperexcitability: An imaging multimodality approach

Abstract

BACKGROUND

Cardiac lipomas are rare benign tumors commonly found in the right atrium or left ventricle. Patients are usually asymptomatic, and clinical presentation depends on location and adjacent structures impairment. Right ventricle lipomas are scarce in the literature. Moreover, the previous published cases were reported in over 18-year-old patients.

CASE SUMMARY

We report a giant right ventricle lipoma discovered incidentally in a 17-year-old female while performing preoperative work-up. The diagnosis was confirmed by histopathological examination, and a conservative approach was performed.

CONCLUSION

Multimodal cardiac imaging and histopathological examination are required for a definitive diagnosis. The therapeutic approach depends on clinical presentation.

Core tip: We describe an extremely rare case of cardiac lipoma raising from the right ventricle in a young patient aged less than 18-years-old. It was discovered incidentally while performing preoperative workup. Variable cardiac imaging modalities such as transthoracic echocardiogram, cardiac computed tomography-scan, positron emission tomography-scan and cardiac magnetic resonance were used. Then, the diagnosis was confirmed by histopathological examination.
