A rare case of segmental arterial mediolysis

Segmental arterial mediolysis (SAM) is a presumably vasospastic disorder [1]. SAM commonly involves large to medium sized intraabdominal, cerebral and rarely coronary arteries. In 1943, Kernohan and Woltman described arteries with features of SAM in the posterior circulation of the brain for the first time [2]. The first case of SAM was presented in 1976 by Slavin and Gonzalez [3]. At first they termed it segmental mediolytic arteritis, but due to lack of inflammatory changes, renamed it segmental arterial mediolysis [3]. We describe an extremely rare case of a combined hemorrhage from an intra-abdominal and intracranial aneurysms.
