Spinal arachnoiditis as a consequence of aneurysm‐related subarachnoid haemorrhage

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.
