title: Lower extremity monoparesis after aneurysmal subarachnoid hemorrhage.
abstract: Two patients presented with acute subarachnoid hemorrhage from a ruptured intracranial aneurysm. Both patients were treated via endovascular coil embolization, and both developed delayed lower extremity monoparesis without associated symptoms that resolved over the ensuing months. An extensive work-up lead us to propose the following hypothesis: the painless peripheral neuropathy likely resulted from nerve root irritation from abundant subarachnoid blood in the lumbar cistern.
