Superior Vena Cava Lipoma in an Asymptomatic Man.

A 58-year-old asymptomatic male smoker, underwent computed tomography of the chest for lung cancer screening. Unenhanced CT showed a hypodense elongated lesion with fat density within the superior vena cava (SVC). Magnetic resonance imaging was performed and confirmed the fatty nature of the lesion. Surgical resection of the lesion was performed and histopathological evaluation confirmed the diagnosis of SVC lipoma.
