Left main coronary artery thrombosis complicating an idiopathic retroperitoneal fibrosis in a 37-year-old man with long-standing type I diabetes mellitus.

Retroperitoneal fibrosis is an uncommon collagen vascular disease of unknown etiology, characterized by the replacement of normal retroperitoneal tissue with fibrosis and/or chronic inflammation usually surrounding the abdominal aorta and the iliac arteries and extending into adjacent anatomic structures. No cases of acute coronary syndrome in the setting of retroperitoneal disorder have been published as yet. We report a 37-year-old man with a 14-year history of type I diabetes mellitus who was admitted to the endocrinology department for a routine check up and glycemic re-equilibration and who was later diagnosed to have an idiopathic retroperitoneal fibrosis. The patient presented during his hospitalisation with a non ST elevation myocardial infarction caused by an isolated thrombus located inside the left main coronary artery successfully treated with manual thrombectomy.
