Bilateral atrial myxomas with multiple arterial aneurysms--a syndrome mimicking polyarteritis nodosa.
This patient, previously described as having polyarteritis nodosa with multiple aneurysms shown by angiography, was recently found to have bilateral atrial myxomas. The angiographic demonstration of multiple cerebral aneurysms has been described in a few cases of left atrial myxoma. This uncommon tumor is also accompanied by "constitutional" manifestations. Thus, a syndrome mimicking polyarteritis nodosa may be produced. Cardiac myxoma should be borne in mind in conditions with multifocal organic involvement, and they should be included in the list of conditions causing multiple arterial aneurysms.
