An Anatomic Curiosity: A Silver of a Liver in an Unusual Location

Video Transcription

Video Summary

A 48-year-old woman undergoing preoperative evaluation for gastric bypass was found to have an incidental right atrial mass on echocardiogram. TEE and cardiac MRI showed a well-circumscribed mass arising from the inferior vena cava and extending into the right atrium. MRI features made acute thrombus, lipoma, myxoma, and malignancy unlikely. She underwent surgical excision, and pathology revealed ectopic hepatic tissue with normal liver architecture. The case highlights the importance of multimodality imaging for right atrial masses and the diagnostic value—and limitations—of cardiac MRI.
