Purpose: To evaluate the treatment and prevention of cerebrospinal fluid (CSF) leakage following removal of the skull base tumors with craniofacial approach.
Methods: A retrospective review was undertaken to analyze the clinical data of 14 cases suffering from CSF leakage after craniofacial surgery for tumors involving the cranial base.
Results: Ten (71.4%) case cured between 3 days and 32 days by conservative treatment including lumbar drainage. Three of four patients who needed operation had no CSF leakage after first attempt. One discontinuous leakage was closed after a second attempt. Among all cases,five(35.7%) patients developed meningitis,and one case died because of serious intracranial infection and respiration failure.
Conclusion: Continuous lumbar cerebrospinal fluid drainage is a safe and effective treatment of CSF leakage following craniofacial surgery. However,If conservative treatment fails to arrest CSF leakage,surgical therapy is recommend with multilayer reconstruction for dural defect so as to avoid meningitis. The vital procedure for prevention of CSF leakage is watertight seal of dura mater, reconstruction of bone defect and obliteration of dead space after craniofacial surgery.

Prevalence and characteristics of microspurs in patients with spontaneous intracranial hypotension compared to the general population.
AJNR Am J Neuroradiol
January 2025
From the Department of Neurosurgery (D.N., L.H., J.G., T.P., R.T.S., A.R., C.M.J.); Department of Neuroradiology (T.D., E.I.P.), Institute of Diagnostic and Interventional Neuroradiology, and Department of Neurology (C.S.), Inselspital, Bern University Hospital, University of Bern, Bern, Switzerland. Department of Neurosurgery (J.B.), Medical Center, University of Freiburg, Freiburg, Germany.
Background And Purpose: In patients diagnosed with spontaneous intracranial hypotension (SIH), microspurs are considered the culprit lesion in most ventral dural leaks (type I). The imaging characteristics of discogenic spurs, and their prevalence in the general population has not been reported in the literature.
Materials And Methods: This observational case-control study was conducted comparing the prevalence and characteristics of discogenic microspurs between SIH patients with a type I leak treated at a tertiary hospital between 2013 and 2023 and an age-and sex matched cohort of trauma patients.
Defining the typical characteristics of orthostatic headache in patients with spontaneous intracranial hypotension.

Headache and Facial Pain Group, University College London (UCL) Queen Square Institute of Neurology and The National Hospital for Neurology and Neurosurgery, Queen Square, London, UK.
Background: Orthostatic headache (OH) is a common feature of various conditions, including spontaneous intracranial hypotension (SIH), but no precise definition currently exists outlining the typical OH characteristics. This ambiguity risks misdiagnosis with unnecessary investigations and delay in institution of treatment. The present study aimed to carry out structured phenotyping of OH in patients with SIH with the aim of outlining its typical characteristics.

AJNR Am J Neuroradiol
January 2025
From the Mayo Clinic, Department of Radiology, Rochester, Minnesota.
The purpose of this video is to introduce digital subtraction myelography for CSF-venous fistula (CVF) detectection. CVF is the most recently identified and likely the most prevalent type of spinal CSF leak that leads to spontaneous intracranial hypotension CVFs are occult on conventional MRI and CT, necessitating the use of myelography for the diagnosis. This video highlights one such technique, which is important because an increasing number of centers are starting to diagnose CVF.

Department of Neurosurgery, Assiut University, Assiut, Egypt.
Background: Causes of cerebrospinal fluid (CSF) rhinorrhea could be divided into primary (spontaneous) and secondary (head trauma and iatrogenic). Idiopathic intracranial hypertension (IIH) has emerged as a cause for spontaneous CSF rhinorrhea but is still underestimated, may be overlooked and needs special consideration in management. The objective of this study is to demonstrate spontaneous CSF rhinorrhea as the primary presentation of IIH and explore the algorithm of management.

With an incidence of 2-5 per million adults, cerebral venous and sinus thrombosis (CVST) is a rarity in the spectrum of cerebrovascular diseases. The etiology and symptomatic presentation are heterogeneous and diverse. CSVT is, therefore, often underdiagnosed.
