Post-operative Pseudomeningocele after Spine Surgery: Rare Cause of Failed Back Syndrome

Abstract

IrJNS. 2016;2(1) 159Background and Importance: Pseudomeningocele is a rare complication of spine surgery, and it is the collection of cerebrospinal fluid in paraspinal tissues. Giant pseudomeningoceles are still rare, and very few cases have been reported in literature. It is usually occult in presentation, and patients do not have any symptoms ascribable to it.Case Presentation: We came across two symptomatic patients with post laminectomy pseudomeningoceles in past one year at our institution. The patients were managed with surgical closure of the dural defect. Both patients were asymptomatic post-operatively and doing well on follow up. Conclusion:Reappearance of neurological symptoms in a patient undergoing spine surgery previously needs careful evaluation. Rarely the symptoms of failed back surgery are seen to be arising due to a pseudomeningocele. Keywords AbstractBackground and Importance

Giant dorsolumbar pseudomeningocele: Unusual evolution of traumatic dural tiny tear

“…Several procedures have been described in literature in the management of pseudomeningoceles. The treatment options include simple observation for spontaneous resolution of small lesions, epidural blood patch, external lumbar subarachnoid drainage, synthetic dural patch, and closure of the dural sac [7]. This observation may encourage spinal surgeons to repair small dural tears to avoid potential CSF leak and its complications.…”

Post-operative Morbidity and Mortality of Lumbar Spinal Stenosis at one Teaching Hospital in North-eastern Benin.

“…Ignorance of a dural tear or a failure to repair can lead to pseudomeningocele or even more serious complications [28]. Pseudomeningocele after spinal surgery is exceptional but not so rare [29,30]. It can occur after an unknown dural breach.…”

Giant lumbar pseudomeningocele after revision lumbar laminectomy: a case report and review of the literature

“…To date, we are aware of 28 reported cases [9,10] of GP. Twenty-one of these cases occurred in the lumbar region and were between 8 and 15 cm in length.…”
