Incidental durotomy during lumbar spine surgery is a commonly reported complication. Those presenting with cerebrospinal fluid (CSF) leak are usually recognized and repaired intraoperatively. In some circumstances, it may either be unrecognised or occur as a delayed complication. Such delayed occurrences cannot be predicted and its management remain a challenge to the surgeon, especially when i...

BACKGROUND Cerebrospinal fluid (CSF) leakages represent a major complication of skull base surgery. Watertight dural suture is challenging, and different ways to reinforce it have been proposed. Since 6 months, we use locally harvested autologous pericranium graft for dural repair in retrosigmoid approach. METHODS Retrospectively, we analyzed 27 patients operated on with key-hole retrosigmoid...

Introduction: A spontaneous pseudomeningocele (PMC) (e.g.without previous surgery or injury) is a rare pathology that may be mimicked as an unilateral polypoid mass in endoscopy or as a mucocele on CT /MRI, which only very exceptionaly doesn’t present with rhinoliquorhea. PMC develops when cerebrospinal fluid (CSF) becomes trapped behind the paranasal sinus mucosa or extracranial soft tissues, ...

Atlantooccipital dislocation can be complicated by a traumatic durotomy that may lead to the rare development of a retropharyngeal pseudomeningocele. To our knowledge this has been reported only five times previously. We present the case of a 60-year-old man involved in a motor vehicle accident who suffered an atlantooccipital dislocation and C5-C6 three-column injury. A unique MRI image of a d...
