[Lysis at the dorsal vertebral bodies showing chronic contained rupture of an aneurysm: about a case].

Chronic contained ruptures of aneurysms are extremely rare. They can result from aneurysm rupture. Indeed, the most dreaded complication of aneurysm is its rupture, which is often fatal. However, haematoma can exceptionally occur after rupture, which is contained by the surrounding anatomical structures, stopping aneurysm from leaking. Unlike the classic rupture, there are no signs of hemorrhagic shock. They are replaced by moderate pain and, often, by atypical signs such as lysis of the dorsal vertebral bodies caused by the occurrence of an hematoma detected by imaging, as in our case. It's important to know this disorder because chronic rupture requires surgical management due to the risk of later rupture of the haematoma.
