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...

An 89-year-old male presented with cerebrospinal fluid (CSF) rhinorrhea associated with head trauma sustained as a pedestrian in a traffic accident. Computed tomography (CT) showed pneumocephalus and multiple cranial bone fractures, including the clivus. Although the CSF rhinorrhea was treated conservatively for a week, clinical symptoms did not improve and surgical repair was performed. Preope...

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...

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 ...

frontal sinus fractures are of surgical importance because of the microbial flora covering the frontal air sinus and it's proximity with the duramater and brain. there is an increased risk of meningitis when fracture of the posterior wall of the frontal sinus is associated with a dural tear. in this condition, communication occurs between the contaminated space of the air sinus and the int...

INTRODUCTION Endoscopic repair is considered the treatment of choice in cerebrospinal fluid (CSF) rhinorrhea. The aim of our study was to analyze the etiopathogenesis of CSF rhinorrhea, the outcome of treatment and the causes of failure in a developing-country setting. MATERIALS AND METHODS A retrospective review of patients treated with endoscopic repair for CSF rhinorrhea at a tertiary care...
