PURPOSE: A recently identified and treatable cause of spontaneous intracranial hypotension (SIH) is cerebrospinal fluid (CSF)-venous fistula, and a recently described computed tomography myelogram (CTM) finding highly compatible with but not diagnostic of this entity is the hyperdense paraspinal vein sign. We aimed to retrospectively measure the prevalence of the hyperdense paraspinal vein sign on CTMs in SIH patients without dural CSF leak, in comparison with control groups. METHODS: Three CTM groups were identified: 1) SIH study group, which included dural CSF leak-negative standard CTMs performed for SIH, with early and delayed imaging; 2) Early control CTMs, which were performed for indications other than SIH, with imaging shortly after intrathecal contrast administration; 3) Delayed control CTMs, which included delayed imaging...

STUDY DESIGN: Retrospective case-control study. OBJECTIVE: To compare the incidence, management, and outcome of incidental durotomy in revision microdiscectomy with open and minimal-access surgery. SUMMARY OF BACKGROUND DATA: Incidental durotomy occurs with a variable incidence of 3%-27% in spine surgery. The highest rate occurs in revision microdiscectomy. The intraoperative and postoperative management of dural tears varies in the literature and the definite impact on clinical outcome has to be clarified...

In this report, we present two cases of patients with cerebrospinal fluid (CSF) otorrhea who underwent surgical repair through either a transmastoid or middle cranial fossa approach. In our first case, a 34-year-old male after head trauma with conductive hearing loss and a House-Brackmann grade 2 facial palsy was found to have a soft tissue mass protruding through his right tympanic membrane. Radiological examination revealed a wide tegmen tympani defect. He underwent surgery via a transmastoid approach with repair of the defect and blind sac closure of the external auditory canal after middle ear cavity obliteration...

BACKGROUND: Secondary cerebrospinal leaks (CSF) are leaks that recur after an initial endoscopic repair of CSF leaks. Identification of characteristics that could predict secondary leaks may allow surgeons to plan repairs with the knowledge that these defects are more likely to fail. OBJECTIVE: To identify characteristics that could predict secondary CSF leaks. METHODS: A search of all studies that reported outcomes after endoscopic repair of CSF leaks was conducted by using medical literature data bases...

BACKGROUND: Anterior transthoracic approaches including thoracoscopic microdiscectomy (TMD) are the preferred technique for central, broad-based, calcified thoracic disc herniations (TDHs). Dural defects due to manipulation or transdural extension may create a potentially life-threatening subarachnoid-pleural fistula. We evaluate a fast, sutureless technique to reconstruct the dura. METHODS: We analyzed 476 anterior transthoracic approaches for TDHs (437 TMDs, 31 mini-thoracotomies, 7 transaxillary approaches, one sternotomy)...

BACKGROUND: Pseudomeningocele, an extradural collection of cerebrospinal fluid (CSF), has only been rarely reported to occur spontaneously in conjunction with isthmic spondylolisthesis (with lysis) in the lumbar spine. CASE DESCRIPTION: A 68-year-old male presented with low back pain and neurogenic claudication of several years duration without any history of trauma, epidural spine injections, or spine surgery. Lumbosacral magnetic resonance imaging (MRI) revealed a grade-I L4-L5 isthmic spondylolisthesis with spinal canal narrowing and a posterior paravertebral collection consistent with CSF...

The value of ICT is important in diagnosis of the diseases of the eye and orbit Methods for direct measurement of intracranial pressure (ICT) are exact, but they are invasive and there is some risk of infection and damage of the tissue. Currently there are 2 valid indirect methods of mesurement of IKT. Digital Ophthalmodynamometry (D-ODM) and Transcranial Doppler ultrasonography (TDU). D-ODM is a non-invasive method for measuring of the Pulsating Venous Pressure (VPT). We can measure VPT by the pulse phenomena...

This is a case report of a 60-year-old male admitted on suspicion of relapse of idiopathic transverse myelitis (TM), who after further diagnostic workup underwent successful closure of a dural arteriovenous fistula (DAVF). Magnetic resonance imaging in DAVF usually shows longitudinal TM, which, unlike DAVF, is also seen with the more common inflammatory or infectious causes usually showing inflammation in the cerebrospinal fluid. The natural history of DAVF is progressive. Since curable options exist, timely diagnosis is most important...

Visual impairment can complicate cerebral venous thrombosis (CVT). Here, we describe the various pathophysiological mechanisms and treatments available. A retrospective chart review of all patients treated for CVT in a large quaternary teaching hospital was done, and cases with visual impairment due to CVT were identified. The various mechanisms causing visual impairment in CVT were (1) raised intracranial pressure (ICP) caused by venous thrombosis without venous infarcts resulting in a benign intracranial hypertension-like presentation of CVT, (2) venous infarcts involving the occipital cortex, (3) raised ICP following the development of a secondary dural arteriovenous (AV) fistula, and (4) arterial occipital infarcts due to posterior cerebral artery compression secondary to herniation in large venous infarcts...

INTRODUCTION: The management of posttraumatic cerebrospinal fluid (CSF) rhinorrhoea remains a clinical challenge. Cerebrospinal fistula is a dural defect responsible for possible CSF leakage into the contiguous air-filled cavities located at the skull base. The risk of central nervous system infection in these conditions is severe and can be life threatening. Consequently, a specific CSF biomarker might be used in case of difficult diagnosis of CSF rhinorrhoea. CSF Tau protein is a neuronal protein, commonly assessed for diagnosis of Alzheimer Disease (AD)...

Cerebrospinal fluid fistula caused by head trauma is a potentially dangerous problem and precise localization and radical treatment are necessary. We present a case of a patient with Panfacial fracture caused by a motorcycle accident, resulting in a cerebrospinal fluid leakage. The correct diagnosis was realized by computed tomography and auxiliary tests. The successful treatment can be confirmed with the support of radionuclide cisternography examination.

PURPOSE OF REVIEW: The purpose of this study is to provide an update on recent developments in the understanding, diagnosis, and treatment of spontaneous intracranial hypotension (SIH). RECENT FINDINGS: SIH is an important cause of headaches caused by spinal cerebrospinal fluid (CSF) leaks, with an increasingly broad spectrum of clinical presentations and diagnostic findings. A simple conception of the condition as being defined by the presence of low CSF pressure is no longer sufficient or accurate...

OBJECTIVES: Arteriovenous malformations (AVMs) of the superior cerebellar vermis and dural arteriovenous fistulas (dAVFs) draining into tentorial venous structures are uncommon lesions. Various surgical approaches and positions have been used to gain access. METHODS: We present our experience with 10 superior vermian AVMs and 3 dAVFs with retrograde transverse sinus or torcular drainage, each resected through a supracerebellar infratentorial approach in the park bench position with modification of the neck and head position (vertex tilt-up instead of down)...

STUDY DESIGN: A retrospective review. OBJECTIVES: To evaluate the therapeutic efficacy of the triple layer closure technique to establish watertight sealing without diversion of lumbar drainage, in preventing persistent incidental subarachnoid-pleural fistula and other neurological complications related to excessive drainage of cerebrospinal fluid (CSF) after dural defect in transthoracic ossified posterior longitudinal ligament (OPLL) surgery. SUMMARY OF BACKGROUND DATA: CSF leakage into the pleural cavity leads to unfavorable conditions for natural healing of incidental durotomy due to the negative pressure environment of the pleural space and lack of wound healing around the bony cavity near the decompressed spinal cord...

BACKGROUND: Various types of lumbar dural punctures may contribute to neurological injury. The etiologies of dural injury include; inadvertent dural punctures due to epidurals placed for labor anesthesia, epidural steroid injections (ESI/transforaminal TESI; approximately 9 million ESI performed in the US per year), deliberate placement of intradural pain devices, and spontaneous cerebrospinal fluid (CSF) fistulas. Resulting neurological complications may include; spinal headaches/intracranial hypotension, subdural hematomas, and 6(th) nerve cranial palsies...
