| Description: | Background: Lipomatous hypertrophy of the interatrial septum is rare, and extension to surrounding structures is extremely uncommon, yet may result in obstructive symptoms requiring surgical resection. Case: This case report describes a 56-year-old male who had been undergoing an outpatient workup for lightheadedness, palpitations, and chest pain. Computed tomography revealed a large mass extending from the superior vena cava to the atrial septum, resulting in compression of the superior vena cava. Magnetic resonance imaging suggested lipomatous characteristics. Subsequently, the patient was referred for cardiac surgery and underwent an uncomplicated resection of the mass and reconstruction of the superior vena cava, with ensuing resolution of the symptoms. Conclusion: Lipomatous hypertrophy of the interatrial septum can rarely expand into the superior vena cava, causing obstructive symptoms. Symptomatic relief may be achieved via resection of the entire mass, which can be performed without violating the atrial septum and atrial wall. |
