Upward migration of the peritoneal catheter of a subgaleo-peritoneal (SP) shunt and coiling into the subgaleal space is an extremely rare complication of a SP shunt. A 32-year-old male patient visited our hospital presenting with a large skull defect due to a prior craniectomy performed elsewhere. The patient underwent a cranioplasty with methylmetacrylate, but subsequently developed progressiv...

A postlaminectomy pseudomeningocele is a spherical, fluid-filled space with fibrous capsule lying dorsal to the thecal canal in the laminectomy opening that occasionally develops after surgery. Eight cases were found in 400 symptomatic postlaminectomy patients undergoing computed tomographic examination. The contents are of cerebrospinal fluid density and may or may not have demonstrable commun...

Background and Importance Lumbar pseudomeningocele is an extradural cystic collection of cerebrospinal fluid with no dural covering. It results from a breach in the dura–arachnoid layer. This rare complication results from a dural rent or dehiscence after laminectomy. The exact cause of postoperative pseudomeningocele incidence is unknown and is usually under reported, as most of these patients...

A 38-year-old man presented with low back pain and sciatica on the left side. Magnetic resonance imaging showed spinal nerve root herniation into a pseudomeningocele associated with lumbar spondylolysis. After closure of the dural defect, the sciatic pain was relieved and subsequently the patient was able to return to work.

Background 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 sym...

It is well known that a traction injury of the brachial plexus may produce tears in the root sleeves resulting in pseudomeningoceles, which are in most instances small and not noticed by the patient. We report 2 unusual cases of giant pseudomeningoceles due to brachial plexus injury presenting as a supraclavicular mass. Compression because of the mass resulted in headache, nausea, and dizziness...
