Lumbar pseudomeningocele is an uncommon complication of lumbar spine surgeries. This occurred due to extradural encapsulated cerebrospinal fluid collection after accidental durotomy or un-repairable dural tear. On review of literature only 58 cases have been reported so far. Magnetic resonance imaging (MRI) is the investigation of choice for diagnosis of pseudomeningocele. Herein author has described a case of iatrogenic pseudomeningocele after lumbar spine surgery and its management.
