We describe a 52-year-old woman who presented with meningitis secondary to a pseudomeningocele within the sphenoid sinus derived from a bony defect in the clivus. The bony defect was radiologically characteristic of an ecchordosis physaliphora (EP). She underwent surgical repair of the defect and had resolution of her symptoms. This case report will discuss the second case of transclival pseudo...

We present a case of craniospinal hypotension in a 45-year-old woman with an associated epidural pseudomeningocele extending the entire length of the spine. The epidural pseudomeningocele was caused by a CSF leak at the T8 level. In addition to typical low-pressure symptoms, the epidural pseudomeningocele caused atypical symptoms characterized by positional thoracic radiculopathy. Craniospinal ...

OBJECTIVE Many surgeons advocate for watertight dural reconstruction after posterior fossa surgery given the significant risk of cerebrospinal fluid (CSF) leak. Little evidence exists for posterior fossa dural reconstruction utilizing monolayer collagen matrix onlay graft in a non-watertight fashion. Our objective was to report the results of using collagen matrix in a non-watertight fashion fo...

Introdução: Pseudomeningocele iatrogênica consiste na laceração do saco dural resultando em vazamento líquido cerebroespinhal (LCR) durante cirurgia da coluna vertebral, como reparo para hérnia de disco. Trata-se um cisto revestido por tecido fibroso e preenchido LCR, sendo sintomático ou assintomático. Nesse sentido, deve-se ressaltar essa complicação cirúrgica com grandes prejuízos ao pacient...

Digital subtraction myelography is described for its utility in the detection of dural leaks associated with pseudomeningoceles. Although myelography, CT, and MR imaging have been described as effective means for diagnosing pseudomeningocele, this complicated entity can be difficult to diagnose.

Aseptic meningitis is a recognised complication after posterior fossa surgery. It is often self limiting but occasionally runs a protracted course requiring repeated CSF examination to exclude infection, and treatment with systemic steroids. A patient is described with aseptic meningitis after posterior fossa surgery who underwent posterior fossa re-exploration nearly 3 years after the initial ...

BACKGROUND Pseudomeningoceles are a rare complication after spinal surgery, and studies on these complex formations are few. METHODS Between October 2000 and March 2008, 11 patients who developed symptomatic pseudomeningoceles after spinal surgery were recruited. In this retrospective study, we reported our experiences in the management of these complex, symptomatic pseudomeningoceles after s...
