Multiple simple renal cysts and sequential, rapid progressive, aneurysmatic aortoiliac and femoral artery disease: case report and review of the literature.

Abstract Multiple simple renal cysts have been linked to aortic aneurysm and connective tissue disease by different authors. We present a case of a 64 year old male patient with multilevel, rapid progressive aneurysmatic disease. Over a period of 11 years, he sequentially developed a symptomatic infrarenal aortic aneurysm of 100 mm, a juxtarenal progression of the aneurysm up to 61 mm, an aneurysm on the descending thoracic aorta of 73 mm and a common iliac aneurysm of 53 mm. In addition, he developed an aneurysm of 69 mm of the left superficial femoral artery and an aneurysm of 53mm of the right profunda femoris artery. Although the exact relationship between multiple simple renal cysts and arterial aneurysm formation is not known, there is a suggestion that they can be a marker for arterial aneurysmatic disease. We therefore would advocate a more thorough follow up in case of aneurysmatic disease in a patient with known multiple simple renal cysts.
