Segmental arterial mediolysis (SAM) is a rare condition and presents with intra-abdominal bleeding which may result in a life-threatening situation. Unruptured aneurysms were rarely exacebated and could be followed-up by contrast-enhanced CT. Understanding and recognizing radiologic features of SAM is critical for an accurate diagnosis and determination of appropriate treatments.  

Review the various clinical manifestations of SAM. Presentation of characteristic imaging findings of SAM including string of beads, fusiform and saccular formation of aneurysms, and arterial wall thickening and dissection. Review the clinical indications and treatment options of transcatheter arterial embolization. Discussion of the diagnostic problems and the treatment strategies.
