Natural Growth of Left Atrial Myxoma.

Abstract

Myxomas are common benign cardiac tumors that can cause life-threatening events. Urgent surgical excision is needed. Therefore, little is known about their growth rate. We present a peculiar case of an incidental left atrial myxoma offering calculation of a growth curve over more than 6 years. The myxoma was incidentally seen retrospectively on computed tomography scans in follow-up for bladder carcinoma in a 71-year-old patient. The patient underwent surgical resection of the myxoma. The authors emphasize that myxoma can be unnoticed on non-electrocardiogram-gated computed tomography scans. In the presented case, cardiac myxoma appears to grow linearly over time.
