Marantic Endocarditis Associated with Metastatic Fibrolamellar Hepatocellular Carcinoma in a Young Adult: About a Case

Abstract

We describe the case of a 21-year-old patient presenting with marantic endocarditis of the aortic valve occurring in the context of underlying metastatic fibrolamellar hepatocellular carcinoma. The patient was admitted due to a pulmonary embolism complicating deep vein thrombosis in the right lower limb. Upon admission, the patient was hemodynamically stable and afebrile, with a poor general condition. Physical examination revealed a painful swelling in the right lower limb extending up to the thigh, hepatomegaly suggestive of a tumor, and moderate ascites. Cardiac auscultation did not reveal any murmurs or abnormal sounds. Laboratory tests showed a non-specific inflammatory syndrome, and blood cultures were negative. The electrocardiogram indicated regular sinus tachycardia. Echocardiography revealed a mobile, hyperechoic mass located on the ventricular aspect of the aortic valve, without regurgitation or stenosis. The patient was started on heparin therapy. Unfortunately, the patient passed away at home two weeks later, and no autopsy was performed.
