Abstract |
Background |
The rupture of an isolated spinal aneurysm is an exceptional occurrence. It might be responsible for a spinal subarachnoid haemorrhage (SSAH) that in rare cases can be complicated by arachnoiditis. Among the former the adhesive type is the most severe leading to the formation of a cyst and/or a syrinx.
Patients and methods |
The literature review was performed via a PubMed search using the following keywords.
Adhesive arachnoiditis; spinal subarachnoid haemorrhage; spinal arachnoiditis; spinal arachnoid cyst; arachnoid cyst .Thesearch yielded 24 articles. Given the fact that only a few studies had been reported on the subject, we decided to include all studies regarding adhesive arachnoiditis after SAH leading to a descriptive literature review. Furthermore, a case illustration of a 57 year old man harbouring this type of rare pathology is described.
Results |
Twenty-four case reports were found regarding spinal adhesive arachnoiditis (SAA) following SSAH. Posterior cerebral circulation bleeding (66.7%) most often occurred followed by spinal (9.1%) and anterior cerebral circulation (9.1%) respectively. The mean time between the haemorrhage and the SAA onset was 10 months. A higher predominance of symptomatic thoracic SAA was found. Including the present case, 80% of patients had a laminectomy, 72% had a micro adhesiolysis, and 56% a shunt placement. Cervical and upper thoracic involvement appeared to have a better outcome.
Conclusion |
Although most authors suggested surgical treatment, the long-term outcome remains unclear. Early stage diagnosis and management of this rare and disabling pathology may lead to a better outcome. Larger co-operative studies remain essential to obtain a better understanding of such a rare and complex disease.
