Repair of giant lumbosacral pseudomeningocele with fast-resorbing polymer mesh in a pediatric patient operated for posterior dysraphism

Surgical management of an ossified giant lumbar pseudomeningocele: A case report

BACKGROUND

Pseudomeningoceles (PMs) are infrequent complications of spine surgery resulting from incidental durotomy and subsequent extravasation of cerebrospinal fluid. Giant PMs (GPMs), defined as ≥8 cm in major diameter, are rarely reported in the literature and present a challenge due to a lack of clear guidelines for surgical management.

CASE DESCRIPTION

Here, the authors discuss the successful surgical management of a 25.3 cm lumbar GPM that became calcified 3 years following an initial T10-S2 laminectomy with instrumented fusion performed at an outside-hospital.

CONCLUSION

This report focuses on the successful 3-year delayed surgical intervention for the management of an ossified GPM.

Repair of refractory postoperative cerebrospinal fluid leakage using a reversed dermis flap in a pediatric lipomyelomeningocele patient

INTRODUCTION

Cerebrospinal fluid (CSF) leak and pseudomeningocele are common complications after surgery for spinal dysraphism.

CASE REPORT AND TECHNIQUE

We report a 6-month-old girl with a lumbosacral lipomyelomeningocele and accessory lower limb who developed a refractory cerebrospinal fluid leak and pseudomeningocele after lipomyelomeningocele repair and removal of the accessory limb. The pseudomeningocele was successfully repaired using a reversed dermis flap made from excess skin that covered the meningocele.

CONCLUSION

This technique can be performed without using synthetic material or an additional surgical incision.
