Abstract

Background Both spinal artery aneurysm and spinal subarachnoid hemorrhage represent a very rare event.

Methods We report a case of a ruptured dissecting aneurysm of the right L1 radiculomedullary artery associated with subarachnoid hemorrhage and severe motor weakness.

Results An urgent decompressive hemilaminectomy was performed due to worsening in motor deficit. A subsequent spinal angiography showed a dissection of radiculomedullary artery of L1 on the right side, treated conservatively.

Conclusion Nowadays, therapeutic strategies for this aneurysm remain controversial. Conservative strategy can represent a valid alternative.

Keywords

subarachnoid hemorrhage - dissection aneurysm - radiculomedullary artery - conservative treatment
