Systemic lupus erythematosus is an inflammatory autoimmune disease of unknown etiology. The coronary lesions are extremely rare, particularly aneurysms.
We report a case of a coronary aneurysm of a patient diagnosed with Systemic lupus erythematosus who showed up at the emergency department presenting, since for 4 hours, an acute retro-sternal chest pain radiating to his jaws.
An electrocardiogram was performed urgently and showed an ST-elevation of 2mm in the infero-basal territories and right leads (V3r, V4r).
The patient underwent coronary angiography which revealed an aneurysmal dilatation of the right coronary artery with multiple atherosclerotic aneurysms of different sizes with no thrombus visualized within the lumen.
Coronary aneurysms are fatal and have potential complications that should be considered in the diagnostic of Cardiac involvement in Systemic lupus erythematosus since early detection might allow complete healing.
