Dissecting aneurysm of the l1 radiculomedullary artery associated with subarachnoid hemorrhage: A case report

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.
