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.
