Iatrogenic lumbar giant pseudomeningocele: A report of two cases.

Background: Iatrogenic lumbar pseudomeningoceles are an uncommon complication of lumbar spinal surgeries. This pathology is an extradural, encapsulated, and cerebrospinal fluid collection which develops as a consequence of an inadvertent, unrepaired dural tear. If a pseudomeningocele grows beyond 8 cm in length, it may be classified as "giant."

Methods: Two adult females with giant pseudomeningoceles due to remote lumbar laminectomy were presented. Both patients were surgically managed.

Conclusions: Iatrogenic lumbar giant pseudomeningocele is rare. Notably, their surgical management is similar to that utilized to treat routine pseudomeningoceles.
