Acquired non-traumatic transethmoidal encephaloceles are very infrequent lesions that are generally caused by a tumor or hydrocephalus. As far as we know, there is no reported case of encephalocele after CSF diversion in the literature. We present a 25-year-old woman with hydrocephalus due to aquiductal stenosis who was treated with endoscopic third ventriculostomy. Nine months later, she had d...

UNLABELLED Cerebrospinal fluid (CSF) rhinorrhea is a leakage of fluid from the subarachnoid space to the frontal, sphenoidal or ethmoidal sinuses. CSF rhinorrhea is a known potential complication with significant morbidity and mortality. It may present a significant challenge in diagnosis, localization and management. STUDY DESIGN Series study. MATERIAL AND METHOD Between 1993 and 2004, 44 ...

INTRODUCTION Cerebrospinal fluid (CSF) rhinorrhea results from an abnormal communication of the dura mater to the nasal mucosa. The majority of cases of CSF rhinorrhea are the result of trauma or surgery involving the skull base. Spontaneous CSF rhinorrhea is a rare clinical entity with increased risk of ascending infection. Delay in diagnosis places the patient at risk of developing meningitis...

Objectives Pseudo-cerebrospinal fluid (CSF) rhinorrhea is a rare phenomenon, presumed to result from aberrant autonomic reinnervation of the paranasal mucosa following injury to the greater superficial petrosal nerve or periarterial plexus. In this report, we discuss the case of a postoperative patient with pseudo-CSF rhinorrhea exacerbated by chewing and propose a novel mechanism of pseudo-CSF...

When patients present with spontaneous cerebrospinal fluid (CSF) rhinorrhea the primary diagnostic goal is localizing the site of leakage so that an appropriate approach for surgical repair can be selected. Metrizamide computed tomography (CT) has become the preferred method for investigating CSF rhinorrhea for several reasons [1-4]. CT provides superb bone detail so that fractures or areas of ...

Two cases of nontraumatic cerebrospinal fluid rhinorrhea were presumed to be an indirect manifesta tion of brain tumor. One patient had a parietal convexity meningioma and the other a cerebello pontine angle neurinoma. Following excision of the tumors these patients spontaneously developed cerebrospinal fluid rhinorrhea, which disappeared after the repair of fistulas at the base of the frontal ...

A radionuclide counting method, performed with the patient prone and the neck flexed, was used successfully to diagnose CSF rhinorrhea in two patients. A normal radionuclide ratio (radionuclide counts in pledget/radionuclide counts in 1-ml blood sample) was obtained in 11 normal control subjects. Significance was determined to be a ratio greater than 0.37. Use of radionuclide counting method of...

In an attempt to improve the diagnosis and to assess the intensity of intermittent cerebrospinal fluid rhinorrhea, indium-111 uptake by nasal pledgets during prolonged cisternography using 111In-DTPA was determined. In 12 patients having suspected cerebrospinal fluid rhinorrhea, cisternograms with calculation of counts/pixel in regions of interest were obtained, blood samples drawn, and nasal p...

INTRODUCTION Spontaneous cerebrospinal fluid leakage is usually caused by developmental abnormalities and is rare, accounting for approximately 5% of the cases of cerebrospinal fluid (CSF) leakage. To the best of our knowledge, clival dysplasia-caused CSF rhinorrhea has never been reported in the neurosurgical field. CONCLUSION Spontaneous cerebrospinal fluid rhinorrhea is often treated by su...
