Abstract

Abstract : Introduction: Segmental arterial mediolysis (SAM) is a rare, non-atherosclerotic, non-inflammatory vascular disease mostly affecting medium to large sized abdominal arteries which may cause aneurysms, stenosis, and haemorrhage. Report: A case is reported of a patient with SAM affecting the renal arteries bilaterally, where the diagnosis was made by excluding other inflammatory, immunological, and infectious mimickers. Discussion: As SAM carries a significant mortality and morbidity from end organ ischaemia, infarction, or haemorrhage, it should be considered in any patient presenting with abdominal pain. Highlights: Segmental arterial mediolysis (SAM) should be considered in a patient presenting with acute severe abdominal pain because of the high mortality risk secondary to haemorrhage. The mechanism of aneurysms, stenoses, and haemorrhage is thought to involve disruption of the arterial media. SAM can be differentiated from its other mimickers by its clinical, laboratory, and radiological findings.
