Description
A myxoma is a benign heart tumor. One that grows on both sides of the wall between the heart's upper chambers is exceptionally rare. Herrera and six co-authors report a 74-year-old woman whose routine heart scan showed a mobile mass in each upper chamber. The two masses were joined by a single stalk passing through the small opening in the dividing wall. Three kinds of imaging confirmed one tumor straddling the wall rather than two separate growths.
Surgeons removed the whole tumor in one piece, and the patient recovered well apart from a brief slow heartbeat. The authors explain that a tumor bridging both chambers can send clots to both the body and the lungs. That makes early complete removal important. They also show how using several imaging methods together maps the tumor's shape and stalk, letting the surgical team plan with care.
