Background and Importance: This interesting case is about the presence of normal pressure hydrocephalus and a large pseudomeningocele at the same time after 13 months of posterior fossa surgery. Although the occurrence of a pseudomeningocele following posterior fossa surgery is not so rare, such a late large pseudomeningocele development with signs and symptoms of NPH after 13 months of surgery...

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 ...

abstract a patient with a 3-month history of headache refractory to pain medication was admitted. the ct scan and mri showed evidence of a posterior fossa mass. this was pathologically confirmed as an extra medullary plasmacytoma (emp). he had a pathologic fracture of the left humerus 7 years ago while the radiologist was unaware at the time of diagnosis. a solitary bone plasmacytoma (sbp) was ...

Posterior fossa ependymoma comprises two distinct molecular entities, ependymoma_posterior fossa A (EPN_PFA) and ependymoma_posterior fossa B (EPN_PFB), with differentiable gene expression profiles. As yet, the response of the two entities to treatment is unclear. To determine the relationship between the two molecular subgroups of posterior fossa ependymoma and treatment, we studied a cohort o...

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...
