A Rare Case of Superior Gluteal Artery Pseudo Aneurysm after Blunt Trauma

Abstract

Prevailing over in rotationally unstable pelvic fractures, acetabular fractures or hip dislocations, superior gluteal artery pseudo aneurysm imperceptibly could be found after blunt force trauma of the pelvic region. We present a case of superior gluteal artery pseudo aneurysm after blunt force trauma that became gradually symptomatic in two months following the prime malevolence. Non-resolving gluteal hematoma presented two months after the incident, disregarding standard treatment methods led the diagnosis to plausible entity of pseudo aneurysm. Standard protocol was followed. CT angiography was indicated and it confirmed the suspected diagnosis. Upon indication a treatment plan was established with correspondent angioembolization of the pathologic substrate. Pseudo aneurism of the superior gluteal artery should be considered as differential diagnosis for unexplained hematomas in the posterior pelvic region following a trauma regardless of its nature.
