Abstract Cerebrospinal fluid (CSF) leakage is a rare but severe complication during dacryocystorhinostomy (DCR). Understanding the details of the anatomy of the lacrimal drainage system and skull base is essential to avoid this complication. We examined the positional relationship between the lacrimal sac and skull base using 16 cadavers (22 sides) and computed tomographic images taken in 81 patients (81 sides). Consequently, the frontal sinus intervened between the lacrimal sac and skull base in 81.8–90.1% of cases. The lacrimal sac fundus and posterior lacrimal crest were far from the skull base/cribriform plate, and the skull base above the lacrimal sac was considerably thick. These results indicate that the risk of skull base injury and following CSF leakage during DCR is extremely low. However, surgeons should be cautious of this complication by indirect injury due to a twisting movement of a bone rongeur applied to the maxillary bone during the creation of a bony window in patients with no interposition of the frontal and ethmoid sinuses between the lacrimal sac and skull base.

Object Persistent posttraumatic cerebrospinal fluid (CSF) leakage frequently complicates skull base fractures. Although many CSF leaks will cease without treatment, patients with CSF leaks that persist greater than 24 hours may be at increased risk for meningitis, and many will require surgical intervention. The authors reviewed their 15-year experience with posttraumatic CSF leaks that persisted longer than 24 hours. Methods The authors reviewed the medical records of 51 patients treated between 1984 and 1998 with CSF leaks that persisted for 24 hours or longer after traumatic head injury. In 27 patients (55%) spontaneous resolution of CSF leakage occurred at an average of 5 days posttrauma. In 23 patients (45%) surgery was required to resolve the leakage. Eight patients (16%) with occult CSF leaks presented with recurrent meningitis at an average of 6.5 years post-trauma. Forty-three (84%) patients with CSF leaks sustained a skull fracture, most commonly involving the frontal sinus, whereas parenchymal brain injury or extraaxial hematoma was demonstrated in only 18 patients (35%). Delayed CSF leaks, with an average onset of 13 days posttrauma, were observed in eight patients (16%). Among patients with clinically evident CSF leakage, the frequency of meningitis was 10% with antibiotic prophylaxis, and 21% without antibiotic prophylaxis. Thus, prophylactic antibiotic administration halved the risk of meningitis. A variety of surgical approaches was used, and no significant neurological morbidity occurred. Three (13%) of 23 surgically treated patients required additional surgery to treat continued CSF leakage. Conclusions A significant proportion of patients with CSF leaks that persist greater than 24 hours will require surgical intervention. Prophylactic antibiotic therapy may be effective in this group of patients. Patients with skull base or frontal sinus fractures should be followed to detect the occurrence of delayed leakage. Surgery-related outcome is excellent.

Abstract Background Cerebrospinal fluid (CSF) leakage is a common complication after neurosurgical intervention. It is associated with substantial morbidity and increased healthcare costs. The current systematic review and meta-analysis aim to quantify the incidence of cerebrospinal fluid leakage in the pediatric population and identify its risk factors. Methods The authors followed the PRISMA guidelines. The Embase, PubMed, and Cochrane database were searched for studies reporting CSF leakage after intradural cranial surgery in patients up to 18 years old. Meta-analysis of incidences was performed using a generalized linear mixed model. Results Twenty-six articles were included in this systematic review. Data were retrieved of 2929 patients who underwent a total of 3034 intradural cranial surgeries. Surprisingly, only four of the included articles reported their definition of CSF leakage. The overall CSF leakage rate was 4.4% (95% CI 2.6 to 7.3%). The odds of CSF leakage were significantly greater for craniectomy as opposed to craniotomy (OR 4.7, 95% CI 1.7 to 13.4) and infratentorial as opposed to supratentorial surgery (OR 5.9, 95% CI 1.7 to 20.6). The odds of CSF leakage were significantly lower for duraplasty use versus no duraplasty (OR 0.41 95% CI 0.2 to 0.9). Conclusion The overall CSF leakage rate after intradural cranial surgery in the pediatric population is 4.4%. Risk factors are craniectomy and infratentorial surgery. Duraplasty use is negatively associated with CSF leak. We suggest defining a CSF leak as “leakage of CSF through the skin,” as an unambiguous definition is fundamental for future research.

<b><i>Introduction:</i></b> Epidural blood patches (EBPs) are rarely performed at the high-level cervical levels. The aim of the study was to investigate the imaging features, safety, and effectiveness of CT-guided percutaneous EBPs for high-level cervical cerebrospinal fluid (CSF) leakage. <b><i>Methods:</i></b> Twenty-five patients with spontaneous high-level (C1–C3) CSF leakage on MRI and CT imaging, including 2 patients with intracranial epidural hematoma caused by CSF, were treated with EBP. Two needles were inserted into the C1–3 bilateral epidural space. The needle location was confirmed by injection of both 3–5mL sterile air and a diluted iodinated contrast agent to delineate its spatial diffusion. The patient’s blood 11.1 ± 3.1 mL was slowly injected to make a patch; the distribution in epidural space was monitored with intermittent CT scanning. <b><i>Results:</i></b> The typical manifestation of CSF leakage was the high signal outside the C1–3 cervical dura on MR T2W fat inhibition images and low density in cervical muscle space on CT images. Twenty patients suffered from headaches and were able to sit and walk 24 h after the operation. Four patients, with partial relief of headache and a small but persistent CSF leakage, were re-treated with EBS. One patient underwent a third operation because of a persistent CSF leakage on MRI. <b><i>Conclusions:</i></b> Imaging of water at the surrounding epidural space of high cervical level is a typical feature of dural rupture on both MRI and CT. CT-guided EBP is safe and efficient for the high-level cervical CSF leakage, especially for cases in which conservative treatments failed.

Object. Spontaneous spinal cerebrospinal fluid (CSF) leakage with development of the intracranial hypotension syndrome and acquired Chiari I malformation due to lumbar spinal CSF diversion procedures have both been well described. However, concomitant presentation of both syndromes has rarely been reported. The object of this paper is to present data in seven cases in which both syndromes were present. Three illustrative cases are reported in detail. Methods. The authors describe seven symptomatic cases of spontaneous spinal CSF leakage with chronic intracranial hypotension syndrome in which magnetic resonance (MR) images depicted dural enhancement, brain sagging, loss of CSF cisterns, and acquired Chiari I malformation. Conclusions. This subtype of intracranial hypotension syndrome probably results from chronic spinal drainage of CSF or high-flow CSF shunting and subsequent loss of brain buoyancy that results in brain settling and herniation of hindbrain structures through the foramen magnum. Of 35 cases of spontaneous spinal CSF leakage identified in the authors' practice over the last decade, MR imaging evidence of acquired Chiari I malformation has been shown in seven. Not to be confused with idiopathic Chiari I malformation, ideal therapy requires recognition of the syndrome and treatment directed to the site of the spinal CSF leak.

Object The purpose of this study was to clarify whether cerebrospinal fluid (CSF) leakage into the subdural space is involved in the genesis of chronic subdural hematoma (CSDH) and subdural hygroma (SH) and to clarify whether this leakage of CSF into the subdural space influences the postoperative recurrence rate of CSDH and SH. Methods In this prospective observational study, 75 cases involving patients treated surgically for CSDH (67 patients) or SH (8 patients) were evaluated with respect to clinical and radiological findings at presentation, the content of β -trace protein (β TP) in the subdural fluid (βTPSF) and serum (βTPSER), and the CSDH/SH recurrence rate. The βTPSF was considered to indicate an admixture of CSF to the subdural fluid if βTPSF/βTPSER > 2. Results The median β TPSF level for the whole patient group was 4.29 mg/L (range 0.33–51 mg/L). Cerebrospinal fluid leakage, as indicated by βTPSF/βTPSER > 2, was found to be present in 93% of the patients with CSDH and in 100% of the patients with SH (p = 0.724). In patients who later had to undergo repeated surgery for recurrence of CSDH/SH, the βTPSF concentrations (median 6.69 mg/L, range 0.59–51 mg/L) were significantly higher (p = 0.04) than in patients not requiring reoperation (median 4.12 mg/L, range 0.33–26.8 mg/L). Conclusions As indicated by the presence of βTP in the subdural fluid, CSF leakage into the subdural space is present in the vast majority of patients with CSDH and SH. This leakage could be involved in the pathogenesis of CSDH and SH. Patients who experience recurrences of CSDH and SH have significantly higher concentrations of βTPSF at initial presentation than patients not requiring reoperation for recurrence. These findings are presented in the literature for the first time and have to be confirmed and expanded upon by further studies.

Paranasal sinus mucocele is a slowly growing benign cystic lesion. It usually involves the frontal and ethmoid sinuses and can extend to adjacent structures, especially to the orbit, skull base and brain parenchyma. Prompt surgical intervention is needed when symptoms occur. Complete resection of mucocele is approached via endoscopic sinus surgery, while marsupialization is also widely considered. Recently, we encountered a case of spontaneous brain herniation and cerebrospinal fluid leakage during endoscopic marsupialization of ethmoid sinus mucocele. Herein, we report the case with a review of the literature.

Isolated cases of spontaneous cerebrospinal fluid (CSF) leakage with and without middle ear encephalocele have been reported. These leaks are usually accompanied by episodes of recurrent meningitis, hearing loss, or chronic headache. In this article, we report seven new cases of spontaneous CSF leakage. Six of these patients had conductive hearing loss and serous otitis media, and three had recurrent meningitis. Prior to a definitive diagnosis, six patients had received myringotomy tubes, which produced profuse clear otorrhea. Three patients had positive beta-2 transferrin assays. Computed tomography and magnetic resonance imaging confirmed a defect in the temporal bone tegmen. A combined transmastoid and middle fossa surgical approach with a three-layer closure was used to repair the tegmen defect. All patients had a lumbar drain placed prior to surgery. In addition to describing the seven new cases, we review the history of CSF leakage and discuss diagnostic methods, surgical findings, and our recommendations for management.
