Systemic embolisms involving cholesterol crystals sometimes occur following vascular catheterization and may be responsible for a variety of clinical signs. The authors report a case in which the etiological diagnosis included a transesophageal echography (TEE) which revealed atheromatous plaques on the thoracic aorta which were probably responsible for the projections. It is possible that episodes of embolism, either fibrinocruoric or due to the release of cholesterol crystals, arising from the thoracic aorta, have hitherto been underestimated by imaging methods such as scans and angiographs.
