Giant Interatrial Septal Lipoma Filling with Right Atrium Causing Slight
Symptoms: A Case Report
Abstract
Cardiac lipoma is extremely rare. Here we presented a unique
illustrative case of interatrial septal lipoma protruding into right
atrial causing symptoms in a 54-year-old male. Echocardiogram and
computed tomography showed a well-shaped, giant and fixed occupying
located in interatrial septum and right atrium. The only manifestation
was palpitation though the mass filled almost all atrium and compressed
superior vena cava. The patient received resection of the large-sized
lipoma sizing 87mm in diameter and weighing ~1000g.
Pathological exam demonstrated mature lipocytes and substantiated the
diagnosis of lipoma. The patient did well postoperatively and symptoms
were resolved.
