Abstract:
Only a few case reports currently exist regarding symptomatic spinal arachnoiditis following aneurysm-related subarachnoid haemorrhage. We present three patients who developed symptomatic spinal arachnoiditis following spontaneous aneurysm rupture. Following initial aneurysm and subarachnoid haemorrhage management (including ventriculo-peritoneal shunt placement), all three patients developed gradually worsening neurological abnormalities, and subsequent imaging demonstrated spinal arachnoiditis. Despite spinal decompression, all three patients experienced progressively worsening neurological decline.
