Left atrial myxoma with embolization presenting as an acute infrarenal aortic occlusion.
We present the case of a 42-year-old woman who had acute total infrarenal aortic occlusion resulting from embolic implantation from a left atrial myxoma. We propose that the small aortic aneurysm that was discovered and repaired in this case may be a direct result of invasion and destruction of the aortic elastic laminae by implanted myxomatous tissue originating in the primary atrial tumor. This behavior has been noted in small vessels of the cerebrum and upper extremities with this lesion, but no prior reports of this occurrence in the aorta has been noted after extensive review of the literature.
