A pseudomeningocoele is an extradural collection of cerebrospinal fluid which results from a dural or arachnoid tear. The fluid is not contained within a protrusion of the meninges, which is typical for a real meningocoele. Although most pseudomeningocoeles probably go unrecognised, due to lack of symptoms, surgeons should maintain an index of suspicion when reviewing postoperative patients. Sy...

Most of the previously reported lumbosacral nerve root avulsions presented with pseudomeningoceles at the time of delayed initial imaging. We report a case of traumatic lumbosacral nerve root injury associated with an isolated femur fracture and demonstrate the evolution of pseudomeningoceles following nerve root avulsions and edema in the perineural fat identified on the initial MR imaging.

This report details a 47 patient, prospective, non-randomized, single-center clinical study to evaluate the safety and performance of a new synthetic dural sealant as an adjunct to standard surgical dural repair techniques to prevent cerebrospinal fluid (CSF) leakage. A consecutive series of patients scheduled for cranial and spinal intradural surgery each received standard dural closures. Afte...

We report a 7-year-old boy with a history of headaches, staring spells and speech delay. His neurological examination showed difficulties with tandem gait but no other cerebellar signs. Head CT showed an incidental mass suggestive of large arachnoid cyst of the posterior fossa. Brain MRI showed a cystic lesion at the inferomedial aspect of the left cerebellar hemisphere that follows CSF on all ...

Iatrogenic spinal cord herniation is a rare complication following spinal surgery. We introduce a posterior trans-dural repair technique used in a case of thoracic spinal cord herniation through a ventral dural defect following resection of ossification of the posterior longitudinal ligament (OPLL) in the cervicothoracic spine. A 51-year-old female was suffering from paraplegia after laminectom...

Two patients were evaluated with somatosensory evoked potentials (SSEPs) before and after CT-guided fluid aspiration from cystic intraspinal lesions. Our objective was to use the information and the clinical response to this procedure to determine the suitability of the patients for surgical intervention. In both patients, one with a pseudomeningocele and the other with a subarachnoid cyst, imp...

In most intracranial surgery cases, a drain catheter is inserted to prevent the collection of the wound hematoma or seroma. A drain catheter is also inserted to drain the hematoma or the cerebrospinal fluid. The drain catheter itself does not cause complications; but many complications occur during its removal, such as hematoma, seroma, air collection and pseudomeningocele formation. To prevent...
