Abstract
Objective:To evaluate the accuracy of preoperative computed tomographic cisternography(CTC) and magnetic resonance hydrography(MRH)in the diagnosis of cerebrospinal fluid(CSF) rhinorrhea. Methods:Retrospective analysis was made on the data of 38 patients diagnosed as cerebrospinal rhinorrhea who completed preoperative HRCT, CTC and MRH examinations in the Department of Otolaryngology Head and Neck Surgery of Tianjin Huanhu Hospital from October 2016 to January 2022. The diagnostic accuracy of preoperative imaging examinations was compared according to the leak location found during operation. Results:Among all the 38 cases with CSF rhinorrhea, the detection rates of HRCT, CTC, and cranial MRH were 31.58%, 89.47%, and 60.53%, respectively. The accuracy of CTC was significantlyhigher than that of MRH ( χ²=8.49, P=0.007), and the accuracy of MRH was significantly higher than that of HRCT (χ²=6.41, P=0.01). Subgroup analyses were performed according to the precise positioning of cerebrospinal fluid rhinorrhea leakage. In patients with cerebrospinal fluid rhinorrhea located in ethmoid sinus, the accuracy of CTC(80.95% vs. 14.29%,P<0.01)and MRH(52.38% vs. 14.29%,P=0.02)were significantly higher than that of HRCT, but the accuracy but the difference between CTC and MRH between CTC and MRH was not statistically significant (P=0.10). The accuracy of CTC was significantly higher than that of MRH (100.00% vs. 61.54%, P=0.04) and HRCT (100.00% vs. 53.85%, P<0.01) in patients with CSF rhinorrhea located in sphenoid sinus. However, there was no significant difference in the accuracy between MRH and HRCT ( P=1.00). However, There was no significant difference in the accuracy of CTC, MRH and HRCT in patients with cerebrospinal fluid rhinorrhea located in frontal sinus. The accuracy of CTC and MRH was 84.62% and 57.69% respectively in 26 patients who failed to detect a CSF rhinorrhea by HRCT, and the difference was not statistically significant(χ²=4.59, P=0.06). Conclusion:The comprehensive application of the multiple imaging methods has important guiding significance for the accurate treatment and prognosis evaluation. CTC and MRH could improve the accuracy of the localization diagnosis of cerebrospinal fluid rhinorrhea.

Abstract
OBJECTIVE To assess the diagnostic efficacy of various imaging methods in patients with suspected cerebrospinal fluid (CSF) rhinorrhea. DATA SOURCES The PubMed, EMBASE, SCOPUS, Web of Science, Cochrane Trials, and Google Scholar databases were searched up to December 2021. REVIEW METHODS Diagnostic accuracy was compared among seven radiological methods: computed tomography (CT), CT cisternography (CTC), magnetic resonance imaging (MRI), magnetic resonance cisternography (MRC), CT + MRI, radionuclide cisternography, and intrathecal gadolinium (Gd)-MRC. Sensitivity, specificity, and accuracy were used as outcomes of the analysis. Both a traditional pairwise meta-analysis and a network meta-analysis were performed. RESULTS Twenty-three trials were included in the analysis. The results of a network meta-analysis performed on a network consisting of seven diagnostic methods showed that all imaging modalities had greater diagnostic accuracy than CT, with the exception of CTC, which had lower sensitivity. Only intrathecal Gd-MRC was significantly superior to other imaging methods with regard to sensitivity and accuracy. Gd-MRC also showed the greatest surface under the cumulative ranking curve values for all of the outcomes (sensitivity: 0.9200; specificity: 0.8364; accuracy: 0.8920). CONCLUSION This network meta-analysis demonstrates that intrathecal Gd-MRC is the most useful diagnostic method to detect CSF rhinorrhea. Laryngoscope, 2022.

Abstract
Objective:To evaluate the application value of magnetic resonance hydrography in determine the leak location of patients with cerebrospinal fluid rhinorrhea. Methods:Clinical data of 58 patients with cerebrospinal fluid rhinorrhea treated in Tianjin Huanhu Hospital from February 2015 to February 2021 were analyzed retrospectively. The leak position was judged by three methods: nasal sinus coronal CT, magnetic resonance hydrography and magnetic resonance hydrography combined with nasal sinus coronal CT. The consistency of the leak position among groups determined by different imageological examination pre-operation was compared with the real leak position found during the operation. Results:The positive rate of magnetic resonance hydrography combined with coronal CT in paranasal sinuses(91.4%) was significantly higher than that of magnetic resonance hydrography(74.1%)(P>0.05). The positive rate of magnetic resonance hydrography(74.1%) was higher than that of CT(43.1%)(P>0.01). Conclusion:The comprehensive application of imaging examination technology has important clinical guiding significance for the correct diagnosis of cerebrospinal fluid rhinorrhea. Magnetic resonance hydrography combined with coronal CT of paranasal sinus can effectively find the leak location, which was suggested as the first choice for preoperative localization of cerebrospinal fluid rhinorrhea.

Abstract
OBJECTIVES To evaluate the usefulness of diagnosis by imaging studies for the localization of cerebrospinal fluid rhinorrhea. METHODS PubMed, SCOPUS, Embase, Web of Science, and Cochrane library databases were searched up to July 2021. True and false positive and negative data were collected along with the characteristics of each study. Methodological quality was assessed using the QADAS-2 tool. RESULTS Sixteen studies involving 472 patients were included. The diagnostic odds ratio of imaging studies was 13.6195 (95% confidence interval [7.4756; 24.8129]; I2 = 28.1%). The area under the summary receiver operating characteristic curve was 0.712. Sensitivity, specificity, negative predictive value, and positive predictive value were 0.8507 ([0.7773; 0.9029]; 72.1%), 0.7827 ([0.6865; 0.8556], 26.8%), 0.5828 ([0.4398; 0.7132]; 67.4%), and 0.9407 ([0.8935; 0.9678]; 59.1%), respectively. In subgroup analysis, there were significant differences in sensitivity (computed tomography, 0.7421; computed tomography cisternography, 0.8872; magnetic resonance imaging, 0.8365; magnetic resonance cisternography, 0.8565; and intrathecal gadolinium magnetic resonance cisternography, 0.9307; radionuclide cisteronography, 0.7097; p = 0.0481), and negative predictive value among imaging modalities (computed tomography, 0.3028; computed tomography cisternography, 0.4848; magnetic resonance imaging, 0.4658; magnetic resonance cisternography, 0.7465; and intrathecal gadolinium magnetic resonance cisternography, 0.8611, and radionuclide cisteronography, 0.5263; p = 0.0046). There were no significant differences among imaging modalities in specificity, positive predictive value, or diagnostic odds ratio (p > 0.05). CONCLUSION Imaging studies can be used in the diagnosis of cerebrospinal fluid rhinorrhea. Gadolinium magnetic resonance cisternography showed the highest diagnostic accuracy. Also, magnetic resonance cisternography showed fair diagnostic accuracy without intrathecal injection. This article is protected by copyright. All rights reserved.

Abstract
Background Cerebrospinal fluid (CSF) rhinorrhea results from abnormal communications between the subarachnoid and sinonasal spaces. Accurate preoperative diagnosis and localization are vital for positive clinical outcomes. However, the diagnosis and localization of CSF rhinorrhea remain suboptimal due to a lack of accurate understanding of test characteristics. Objective This systematic review aims to assess the diagnostic accuracy of various tests and imaging modalities for diagnosing and localizing CSF rhinorrhea. Methods A systematic review of the MEDLINE and EMBASE databases was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results Our search identified 4039 articles—53 cohort studies and 24 case series describing 1622 patients were included. The studies were heterogeneous and had a wide range of sensitivities and specificities. Many specificities were incalculable due to a lack of true negative and false positive results, thus precluding a meta-analysis. Median sensitivities and specificities were calculated for cohort studies of the following investigations: high-resolution computed tomography (HRCT) 0.93/0.50 (sensitivity/specificity), magnetic resonance cisternography (MRC) 0.94/0.77, computed tomography cisternography (CTC) 0.95/1.00, radionuclide cisternography (RNC) 0.90/0.50, and contrast-enhanced magnetic resonance cisternography (CEMRC) 0.99/1.00, endoscopy 0.58/1.00, topical intranasal fluorescein (TIF) 1.00/incalculable, intrathecal fluorescein (ITF) 0.96/1.00. Case series were reviewed separately. Etiology and site-specific data were also analyzed. Conclusion MR cisternography is more accurate than high-resolution CT at diagnosing and localizing CSF rhinorrhea. CT cisternography, contrast-enhanced MR cisternography, and radionuclide cisternography have good diagnostic characteristics but are invasive. Intrathecal fluorescein shows promising data but has not been widely adopted for purely diagnostic use. Office endoscopy has limited data but does not sufficiently diagnose CSF rhinorrhea independently. These findings confirm with current guidelines and evidence.

Abstract
OBJECTIVE CSF leakage is a potentially fatal condition that may result when a skull base dural defect permits CSF communication between the cranial vault and sinonasal cavities. Flow rate is an important property of CSF leaks that can contribute to surgical decision-making and predispose patients to complications and inferior outcomes. Noninvasive preoperative prediction of the leak rate is challenging with traditional diagnostic tools. The present study compares fluid configurations on early and late volumetric extended echo train T2-weighted MRI by using image tracings and sequence subtraction as a novel method of quantifying CSF flow rate, and it correlates radiological results with intraoperative findings and clinical outcomes. METHODS A total of 45 patients met inclusion criteria for this study and underwent 3-T MRI. Imaging sequences included two identical CUBE T2 (vendor trade name for volumetric extended echo train T2) acquisitions at the beginning and end of the scanning session, approximately 45 minutes apart. Twenty-five patients were confirmed to have definitive spontaneous or traumatic anterior skull base CSF leaks. Semiautomated volumetric segmentation of CSF intensity was performed on both CUBE data sets by using 3D-Slicer software, and volumes were subtracted to obtain accumulated CSF volume. These imaging-derived fluid accumulations were correlated with high- or low-flow states, as well as ultimate treatment outcomes including recurrences. RESULTS Of the 45 patients, 25 (55.6%) had definitive evidence of CSF leakage, and 22 (88%) of these underwent surgical repair. Patients with high-flow CSF leaks had higher early (4.058 cm3 vs 0.982 cm3, p = 0.04), late (4.58 cm3 vs 1.096 cm3, p = 0.04), and accumulated (0.53 cm3 vs 0.11 cm3, p = 0.01) fluid volume measurements than patients with low-flow leaks. The 5 (22.7%) patients who exhibited postoperative CSF leak recurrence had significantly greater early (6.30 cm3 vs 1.23 cm3, p = 0.008) and late (6.87 cm3 vs 1.45 cm3, p = 0.008) volumes. Accumulated volume was not significantly greater in patients with leak recurrence (0.58 cm3 vs 0.22 cm3, p = 0.07). Early, late, and accumulated volumes were significantly correlated with postoperative hospital stay as well as duration of postoperative lumbar drain placement (p < 0.05 for all measures). CONCLUSIONS High-resolution CUBE T2 MRI, coupled with precise volumetric segmentation and subtraction of sinonasal hyperintensity, not only demonstrated predictive value in differentiating low- and high-flow CSF leaks, but also correlated with postoperative complications such as leak recurrence. These findings may be useful in the clinical workup and neurosurgical management of patients with skull base CSF leaks.

Abstract
Background The use of MR cisternography with intrathecal administration of gadolinium-based contrast agents (GBCAs) is limited by a lack of understanding of the relationship between intrathecal GBCA exposure and dose-related adverse events. Purpose To perform a systematic review to establish an understanding of the dose-response relationship of intrathecal GBCAs and to characterize related adverse events, particularly at higher doses. Materials and Methods Medline, Embase, CINAHL, and Central databases were searched for studies reporting intrathecal GBCA use. Data extraction included studies focused on rates and types of adverse events after intrathecal GBCA exposure. A two-tailed independent sample t test statistic was used to evaluate the relationship between GBCA dose and the presence of serious versus nonserious adverse events. Meta-analysis was used to determine the overall incidence of adverse events. Study quality and publication bias were assessed using the modified Newcastle-Ottawa scale and a funnel plot (effect size measured using Hedges' g followed by the Egger test), respectively. Results Fifty-three studies with a total of 1036 patients were included for analysis. The overall rate of adverse events after intrathecal administration of GBCA was 13% (95% confidence interval [CI]: 9.3%, 18%). Meta-analysis revealed moderate heterogeneity (I2 = 62%). Serious adverse event rates could not be determined with meta-analysis. They were reported in 10 studies and were primarily neurologic in nature, with two cases of coma-one resulting in death. Serious adverse events were associated with significantly higher GBCA doses when compared with nonserious adverse events (mean difference, 4.5 mmol; 95% CI: 2.3 mmol, 6.6 mmol; P = .008). For serious adverse events, there was no clear dose-dependent increase in severity above 2.0 mmol. Conclusion Overall, intrathecal administration of GBCAs at doses greater than 1.0 mmol are associated with serious neurotoxic complications with relative clinical safety at lower doses. © RSNA, 2020 Online supplemental material is available for this article.

Abstract
OBJECTIVES Cerebrospinal fluid (CSF) rhinorrhea in children is relatively uncommon. Endoscopic repair techniques in adults have become first line for nasal-based CSF leaks, and this meta-analysis looks at the success rates of CSF leak cessation following endoscopic repair in children. METHODS Three researchers extracted information involving patient population, surgical technique, outcomes of interest, and study design. A computerized search of MEDLINE, EMBASE and the Cochrane library (January 1990-September 2019) looked for several papers on the subject of CSF leak repair in children using endoscopic technique. RESULTS A total of 15 studies met inclusion criteria. Endoscopic repair of CSF rhinorrhea in children shows a pooled weighted success rate of 94% after first attempt. The most common etiology was traumatic followed by congenital. Iatrogenic defects secondary to tumor resection are becoming more common. The high success rate was irrespective of the techniques using. CONCLUSION Endoscopic repair techniques have a highly successful closure rate for children presenting with CSF rhinorrhea.

Abstract
PURPOSE Intrathecal gadolinium-enhanced MR cisternography (IGE-MRC) has a high sensitivity to detect accurate localization of cerebrospinal fluid (CSF) leakage in otorhinorrhea patients. Our purpose in this study was to describe our experience in analyzing clinically suspected CSF leakage by IGE-MRC by using gadobutrol with emphasis on its safety and diagnostic performance. METHODS We retrospectively reviewed our imaging and clinical database for the evaluation of patients admitted to our clinic with complaints of otorhinorrhea between 2017 and 2019. Two radiologists evaluated the imaging studies independently. Consensus data was used in the analysis. Medical record review and phone call were used for the follow-up. RESULTS Of the 85 patients included in the retrospective analysis, 82 (96.5%) had rhinorrhea and 3 (3.5%) had otorrhea. Overall, 29 patients (34.1% of all patients) underwent operation for repair of the CSF leakage site. Beta-transferrin test was available and positive in 33 patients (38.8%). Five (5.9%) patients complained headaches after the procedure and complaints were resolved with increased water intake. Postprocedurally, 3 patients (3.5%) had vertigo and 1 patient (1.2%) complained nausea but spontaneous regression were observed in a few hours. None of the patients experienced a significant complication or adverse reaction during follow-up period. Sixty-seven patients (78.8%) had medical record and telephone follow-up. Mean follow-up duration with call was 14.2 months. CONCLUSION IGE-MRC is a minimally invasive and highly sensitive imaging technique. The current results during our follow-up demonstrate the relative safety and feasibility of IGE-MRC by using gadobutrol to evaluate CSF leakage.

Abstract
OBJECTIVE Damage to the dura mater often occurs in trauma cases of the head and spine, surgical procedures, lumbar punctures, and meningeal diseases. The resulting damage from dural tears, or durotomy, causes cerebrospinal fluid (CSF) to leak out into the surrounding space. The CSF leak induces intracranial hypotension, which can clinically present with a range of symptoms not limited to positional headaches which can confound accurate diagnosis. Current methods of evaluation and management of dural tears are discussed herewith, as well as the present understanding of its etiology, which may be classified as related to surgery, procedure, trauma, or connective tissue disorder. METHODS We piloted a MEDLINE® database search of literature, with emphasis on the previous five years, combining keywords such as "cerebrospinal fluid leak," "surgery," "procedure," and "trauma" to yield original research articles and case reports for building a clinical profile. RESULTS Patients with suspected dural tears should be evaluated based on criteria set by the International Headache Society, radiological findings, and a differential diagnosis to accurately identify the tear and its potential secondary complications. Afflicted patients may be treated promptly with epidural blood patches, epidural infusions, epidural fibrin glue, or surgical repair. At this time, epidural blood patches are the first line of treatment. Dural tears can be prevented to an extent by utilizing minimally invasive techniques and certain positions for lumbar puncture. Surgical, trauma, lumbar puncture, and epidural injection patients should be observed very carefully for dural tears and CSF leaks as the presenting clinical manifestations can be highly individualized and misguiding. CONCLUSION Because studies have demonstrated a high frequency of dural tears, particularly in spinal surgery patients, there is a need for prospective studies so that clinicians can develop an elaborate prevention strategy and response to avoid serious, unseen complications.

Abstract
Objectives: In the present study, the authors presented the intrathecal gadolinium enhanced MR-myelography findings of patients with spontaneous intracranial hypotension. Materials and Methods: Intrathecal gadolinium enhanced MR-myelography (Gd-MR-myelography) examinations between October 2012 and September 2018 in patients having clinical and radiological findings of spontaneous intracranial hypotension were evaluated retrospectively. Sites and types of contrast leakages in 20 patients who met inclusion criteria were reviewed. All patients had undergone T1-fat suppressed sagittal images of cervical, thoracic and lumbar region after the off label intrathecal injection of 1 ml gadolinium-based contrast agent. Results: Patients (18 female, 2 male) are aged between 23 and 62 years-old (mean age: 41.1). Cerebrospinal fluid (CSF) leakages were cervical in 6 patients, thoracic in 5 patients, lumbar in 5 patients. One patient had leakage in multiple levels on both cervical and thoracic region and another patient on both cervical-thoracic and lumbar regions. No patients had adverse effects related to intrathecal injection of gadolinium. Conclusions: Gd-MR-myelography is effective imaging modality to reveal spinal CSF leakages in patients with spontaneous intracranial hypotension.

Abstract
BACKGROUND The direct costs associated with different diagnostic algorithms to localize cerebrospinal fluid (CSF) rhinorrhea have not been described. METHODS A decision-tree analysis of imaging modalities used to localize CSF rhinorrhea was performed to compare associated direct costs. The primary outcome was cost, which was determined based on reimbursement data published by the Centers for Medicare and Medicaid Services in 2018. The model was parameterized after a literature review of published studies was performed from 1990 to 2018 to estimate the sensitivity CSF rhinorrhea localization of the following radiographic modalities: high-resolution computed tomography (HRCT), magnetic resonance cisternography (MRC), and CT cisternography (CTC). In addition to base case analysis, 1-way sensitivity analyses were also performed to evaluate the robustness of results to changes in model parameters. RESULTS Among patients with a high suspicion for CSF rhinorrhea, use of HRCT followed by exploration in the operating room if preliminary HRCT was negative was found to be the optimal localization modality from a cost perspective ($172.25). The next least costly algorithm was HRCT followed by MRC ($294.10). Imaging algorithms beginning with CTC were the next least costly modality ($727.37). Sensitivity analyses generally supported HRCT to be the optimal initial radiographic strategy over a wide range of parameter values. CONCLUSION This work advocates HRCT as first-line modality to localize CSF rhinorrhea from a cost perspective. Although algorithms beginning with MRC were on average $35 more expensive than those starting with CTC, associated risks of CTC were not modeled and may play a role in decision making.

Abstract
CSF leak from Lateral Recess of Sphenoid (LRS) sinus accounts for 35% of all CSF rhinorrhoea cases. There are various surgical techniques described for repair of LRS CSF leak. This study describes the experience of LRS leak repair in a tertiary care center with three different surgical techniques. Study comprises of 3 cases of LRS CSF leak that presented to J.S.S. Hospital, during the time period of July 2018-January 2019, who underwent endoscopic CSF leak repair. All three cases underwent endoscopic endonasal transpterygoid approach to the leak site. The closure technique opted for all three cases were different. For the first case free mucosal flap from ipsilateral middle turbinate was used, for the second ipsilateral nasoseptal flap (NSF) was used and contralateral NSF was used for the third. All the cases were followed up for a minimum of 3 months. In all the 3 cases the CSF leak site was located in the lateral recess of Sphenoid sinus. Encephalocele was noted in two cases, which were cauterised and closure was done as planned. Crusting was more in cases that underwent closure using free mucosal flap. Healing and take up was similar for both the ipsilateral NSF and contralateral NSF. The endoscope has revolutionized the management of CSF leak from the lateral recess of sphenoid sinus. These defects can be managed efficiently using multilayer closure of defect. For large defects, the Posterior nasoseptal flaps can be used. In addition, contralateral PNSF has lower chances of being devascularized due to injury to pedicle while drilling the pterygoid plates.

Abstract
Nasal liquorrhea is cerebrospinal fluid leakage from cerebrospinal fluid spaces of the cerebral cavity into the nasal cavity or paranasal sinuses due to congenital or acquired abnormalities of the skull base bones and meninges of various etiologies. The severity of liquorrhea varies from hidden manifestations to profuse leakage of cerebrospinal fluid from the nasal cavity. The diagnosis of overt nasal liquorrhea is not problematic, but the diagnosis of latent liquorrhea is a challenge. In this case, the disease leads to potentially fatal complications, such as meningitis (the risk amounts to 10-37%), pneumocephaly, pneumonia, etc. These peculiarites give rise to two main tasks: early diagnosis confirming liquorrhea and accurate identification of the CSF fistula location when planning further surgical management. PURPOSE The study purpose was to review and comparatively analyze all modern methods of diagnosing nasal liquorrhea as well as to substantiate the most effective and promising approaches and algorithms. MATERIAL AND METHODS The study included papers in English and Russian found in the Pubmed database and related to the diagnosis of basal liquorrhea of different etiology and localization. RESULTS This review demonstrates that diagnostic tests vary widely in sensitivity, specificity, accuracy, invasiveness, and cost. Given all the criteria, detection of beta-2 transferrin or beta-trace protein is the best method for confirming nasal liquorrhea, and high-resolution computed tomography is the best technique for localization of the abnormality. CONCLUSION Based on the review, we suggest a diagnostic algorithm for nasal liquorrhea. However, the evidence presented in this review is unfortunately not very reliable, which indicates the existing need for more accurate studies.

Abstract
INTRODUCTION Diagnosis of cerebrospinal fluid (CSF) leaks traditionally involves laboratory testing of markers and appropriate imaging. Surgical localization can be difficult, and the inability to accurately localize skull base defects leads to increased rates of repair failure and complications. Many imaging techniques localizing and identifying CSF leaks have been proposed. Comparisons of current and investigational imaging techniques used to localize CSF leaks are reviewed. METHODS A comprehensive and systematic search through PubMed, Scopus, and reference lists from relevant articles was completed to identify literature on sensitivities of different imaging methods for localization and detection of CSF leaks. Prospective, retrospective, and case series published since 1995 that addressed imaging techniques for CSF leaks confined to the skull base were included. Sensitivities of each major imaging technique proposed were recorded and analyzed. RESULTS In total, 133 studies initially were screened from 2125 studies on preliminary search. Of these, 38 studies were included based on inclusion criteria. Studies were segregated by imaging modality. A total of 1000 patients with CSF leaks subsequently were evaluated. CONCLUSIONS Although radionuclide cisternography has been the historical standard, recent imaging techniques have emerged considering the low sensitivity. Computed tomography cisternography with contrast also has low sensitivity, even in active leaks. Although high-resolution computed tomography is commonly the initial study of choice, magnetic resonance imaging methods, particularly 3-dimensional imaging, may prove to be a more sensitive study of choice. Computed tomography/magnetic resonance imaging combination methods may show promise in localizing CSF leaks. Stratifying by status and etiology may be an important determinant. Further studies investigating various imaging techniques for localizing CSF leaks are needed.

Abstract
Cerebrospinal fluid (CSF) leaks are extracranial egress of CSF into the adjacent paranasal sinus or tympanomastoid cavity due to an osteodural defect involving skull base. It can be due to a multitude of causes including accidental or iatrogenic trauma, congenital malformations and spontaneous leaks. Accurate localization of the site of the leak, underlying causes and appropriate therapy is necessary to avoid associated complications. In this paper relevant anatomy, clinical diagnosis, imaging modalities and associated findings are discussed along with a brief mention about management.

Abstract
PURPOSE Despite a considerable amount of literature that has been published about the use of intrathecal gadolinium-enhanced MR cisternography (IGE-MRC), there is still relatively lack of evidence as to its long-term effects. Our purpose in this study was twofold: firstly, to assess the long-term safety of the IGE-MRC; secondly, to evaluate the diagnostic performance of IGE-MRC for detecting cerebrospinal fluid (CSF) leak in otorhinorrhea patients. METHODS We retrospectively reviewed our imaging and clinical database for the patients admitted to our department for the evaluation of their otorhinorrhea between 2008 and 2017. Two radiologists evaluated the imaging studies independently. Consensus data was used in the analysis. Medical record review and phone call were used for the long-term follow-up. RESULTS The retrospective review yielded 166 patients. Rhinorrhea was present in 150 (90.4%) patients and otorrhea in 16 (9.6%) patients. Overall, 67 patients (40.5% of all patients) underwent operation for repair of the CSF leak site. Beta-transferrin test was available and positive in 57 (34.3%) patients. Overall sensitivity of IGE-MRC and paranasal high-resolution CT (HRCT) was 89.3 and 72%, respectively. Within the first 24 h after the procedure, none of the patients experienced a significant complication or adverse reaction. Ninety-nine patients (59.6%) had medical record and telephone follow-up. The mean follow-up duration with call was 37.1 months. Three (3%) patients complained about severe headache 3-4 weeks after the procedure. CONCLUSIONS IGE-MRC is a minimally invasive and highly sensitive imaging technique. No adverse side effect during our long-term follow-up might strengthen and support the safety of IGE-MRC.

Abstract
BACKGROUND This study aimed to assess the efficacy of MR images with three-dimensional sampling perfection with application optimised contrast using different flip-angle evolution (3D-SPACE) sequence for detecting cerebrospinal fluid (CSF) rhinorrhea and image-guided surgery for the management of CSF rhinorrhea. MATERIALS AND METHODS This study included 45 consecutive patients with suspected CSF rhinorrhea from 2010 to 2015. Patients underwent preoperative MRI scan including 3D-SPACE and conventional T2-weighted (T2W) protocol. Two-blinded neuroradiologists determined the presence and location of CSF leakage. Imaging results were compared with surgical findings and/or β-2 transferrin testing. Intraoperative navigation was used during endonasal endoscopic surgery for repairing CSF rhinorrhea. RESULTS 3D-SPACE sequence correctly described 27 cases (93.1%) and conventional T2W sequence described only 20 (69.0%) of the total 29 patients with truly positive CSF leakage. The sensitivity, specificity, positive predictive value and negative predictive value for detecting CSF leakages were 93.1%, 87.5%, 93.1%, and 87.5% for 3D-SPACE, and 69.0%, 81.3%, 87.0% and 59.1% for T2W, respectively. To repair the leakage, 3D-SPACE image-guided navigation was used to locate the CSF leakage sites intraoperatively. Only two CSF leakage sites proved by surgery were missed by navigation. Successful endoscopic repairs were achieved in 25 of 26 (96.2%) patients during the first attempt. During the follow-up, there were no major postoperative complications or recurrences encountered. CONCLUSION MR imaging with 3D-SPACE sequence is an effective and reliable method with higher sensitivity and specificity than T2W for detecting CSF leakage. Intraoperative 3D-SPACE image-guided navigation is helpful in locating the sites of the CSF leakage during endonasal endoscopic surgery.

Abstract
BACKGROUND Cerebrospinal fluid (CSF) rhinorrhea, when left untreated, can lead to meningitis and other serious complications. Treatment traditionally has entailed an open craniotomy, although the paradigm has now evolved to encompass endoscopic procedures. Trauma, both accidental and iatrogenic, causes the majority of leaks, and trauma involving skull base and facial fractures is most likely to cause CSF rhinorrhea. Diagnosis is aided by biochemical assay and imaging studies. METHODS We reviewed the literature and summarized current practice regarding the diagnosis and management of CSF rhinorrhea. RESULTS Management of CSF leaks is dictated by the nature of the fistula, its location, and flow volume. Control of elevated intracranial pressure may require medical therapy or shunt procedures. Surgical reconstruction utilizes a graduated approach involving vascularized, nonvascularized, and adjunctive techniques to achieve closure of the CSF leak. Endoscopic techniques have an important role in select cases. CONCLUSION An active surgical approach to closing CSF leaks may provide better long-term outcomes in some patients compared to more conservative management.

Abstract
BACKGROUND Diagnostic strategies employed for cases of cerebrospinal fluid (CSF) rhinorrhea vary widely due to limited evidence-based guidance. METHODS A systematic review of the literature was performed using PubMed, EMBASE, and Cochrane databases from January 1990 through September 2014, to examine 9 diagnostic and localization modalities for CSF rhinorrhea. Benefit-harm assessments, value judgments and recommendations were made based on the available evidence. Study exclusion criteria were language other than English, pre-1990 studies, case reports, and nonrhinologic leak. All authors agreed on recommendations through an iterative process. RESULTS We reviewed 68 studies examining 9 practices pertinent to the diagnosis of CSF rhinorrhea, with a highest aggregate grade of evidence of C. The literature does not support the use of the ring sign, glucose testing, radionuclide cisternography (RNC), or computed tomography cisternography (CTC) for identification of CSF leak. Beta-2 transferrin is the most reliable confirmatory test for CSF leak. High-resolution CT (HRCT) is then recommended as the first-line study for localization. Magnetic resonance cisternography (MRC) should be used for CSF leak identification as a second line for each of these if beta-2 transferrin is not available or if HRCT is ambiguous. Intrathecal fluorescein (IF) may also be of benefit in certain clinical scenarios. CONCLUSION Despite relatively low levels of evidence, recommendations for the diagnosis and management of CSF rhinorrhea can be made based on the current literature. Higher-level studies are needed to better determine optimal diagnostic and clinical management approaches.
