NASCI case of the month: pericardial hemangioma

Pericardial hemangiomas are extremely rare benign vascular tumors, accounting for 2-5% of benign cardiac neoplasms Jacob et al. (31(3):7547-57, 2021). These tumors can arise from the endocardium, myocardium, or pericardium, and are often discovered incidentally Priya et al. (4(5): 2406, 2023). Cardiac magnetic resonance (CMR) imaging is crucial for characterizing these masses through distinctive features including high T2-weighted signal intensity, discontinuous peripheral nodular enhancement pattern, and contrast fill-in on late gadolinium enhancement Zeina et al. (115(10):e315-e316, 2007). We present a case demonstrating the diagnostic utility of CMR in differentiating pericardial hemangioma from malignant processes.
