treatment of hydrocephalus in posterior fossa tumors in children is still a matter of controversy and different centers have their own routines. in this regard, hospital records of all children with posterior fossa tumors treated in our center during the interval of 1985-1995 were reviewed. patients’ demographic and diagnostic data were analyzed and the frequencies of shunting procedures were d...

Spontaneous cerebrospinal fluid (CSF) leak is a recognized cause of spontaneous intracranial hypotension (SIH). Subdural hematoma (SDH) is a serious but rare complication of SIH. An autologous epidural blood patch at the CSF-leak site can effectively relieve SIH. We report a case of bilateral SDH with SIH caused by a CSF leak originating at the C1-2 level. A 55-year-old male complained of ortho...

enterobius vermicularis is a nematod of large intestine in man. extra intestinal localization of this parasite is rare. a 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. in laboratory examination of cerebrospinal fluid (c.s.f), the appearance was red, albu-min level was high and the glucose showed normal value. haematoxylin and eosin stained slides pr...

Introduction: Leakage of cerebrospinal fluid in the skull base may be accompanied with recurrent meningitis. The site of leakage may either be anterior (in the nose and paranasal sinuses) or posterior (in the temporal bone). Various imaging techniques can be used to precisely locate the point of leakage but despite all the advances in imaging techniques there are still some rare cases in which ...

mumps infection is endemic in iran. our objective was to evaluate the presence of anti mumps antibodies ( igm & igg) in cerebrospinal fluid in mumps meningoencephalitic children. a prospective/cross-sectional study was performed in tehran, iran (2003 to 2004) and serum anti mumps antibodies (igm) were detected (quantitive; elisa) in meningoencephaltis patients. specific anti mumps antibodies (i...

objective cerebrospinal fluid (csf), its secretion, circulation and absorption have been the subject of recent researches. there is a general agreement that the main site of csf secretion is in the choroids plexus. however, the main absorption site is controversial. some believe that arachnoid granulations are the principle sites of csf absorption. in this study, different locations of csf abso...

INTRODUCTION  Suboccipital craniotomy is a workhorse neurosurgical operation for approaching the posterior fossa but carries a high risk of pseudomeningocele and cerebrospinal fluid (CSF) leak. We describe our experience with a simple T-shaped fascial opening that preserves the occipital myofascial cuff as compared to traditional methods to reduce this risk. METHODS  A single institution, ret...

Introduction. Spontaneous nontraumatic pneumocephalus (PNC) and cerebrospinal fluid (CSF) leaks are both very uncommon conditions. We report a rare case of spontaneous pneumocephalus associated with CSF leak secondary to right sphenoid sinus bony defect without history of trauma. Case Description. 51-year-old Hispanic female with past medical history of hypertension and idiopathic intracranial ...

INTRODUCTION Congenital anomalies of the cochlea and labyrinth can be associated with meningitis and varying degrees of hearing loss or deafness. Despite antibiotics, meningitis remains a life threatening complication. CASE REPORT We report a case of recurrent meningitis following episodes of otitis media in a cochlear implantee child with bilateral vestibulocochlear malformation, due to fist...

Cerebrospinal fluid (CSF) leaks may occur after acoustic neuroma resection. These leaks are usually the result of an iatrogenic injury during removal. The retrosigmoid approach is commonly associated with leaks that occur through the lateral end of the internal auditory canal, through the perilabyrinthine cells extending to the region of the internal auditory canal, or through the retrosigmoid ...
