Stefania Bianchi Marzoli, Alessandra Criscuoli
Pain occurs with optic neuropathies associated with inflammatory central nervous system diseases (MS and NMO), idiopathic intracranial hypertension and spontaneous hypotension, giant cell arteritis, immunomediated systemic diseases, compressive lesions, or infective disorders. Pain can precede the onset of visual loss in acute optic neuritis, it can be irradiated to the orbital region in giant cell arteritis and parasellar compressive optic neuropathies, or it may be located to the back of the eye with posterior scleritis...

Peter G Kranz, Linda Gray, Timothy J Amrhein
OBJECTIVE: To discuss common myths and misperceptions about spontaneous intracranial hypotension (SIH), focusing on common issues related to diagnosis and treatment, and to review the evidence that contradicts and clarifies these myths. BACKGROUND: Recognition of SIH has increased in recent years. With increasing recognition, however, has come an increased demand for management by neurologists and headache specialists, some of whom have little prior experience with the condition...

Spontaneous intracranial hypotension (SIH) has been increasingly recognized as a phenomenon caused by cerebrospinal fluid (CSF) leaks; however, its pathogenesis is still unclear. Here, we report two cases of SIH as a result of CSF leak from a meningeal diverticulum at the C2 nerve root sleeve. The first case is that of a 46-year-old man who had suffered from orthostatic headache after a bicycle accident at age 45. Computed tomography (CT) myelography revealed CSF leaks at the C1/2 level. He underwent epidural blood patch (EBP) therapy, but it was unsuccessful...

Objective  An epidural blood patch (EBP) is the mainstay of treatment for refractory spontaneous intracranial hypotension (SIH). We evaluated the treatment efficacy of targeted EBP in refractory SIH. Methods  All patients underwent brain magnetic resonance imaging (MRI) with contrast and heavily T2-weighted spine MRI. Whole spine computed tomography (CT) myelography with non-ionic contrast was performed in 46 patients, and whole spine MR myelography with intrathecal gadolinium was performed in 119 patients...

The aim of this study is to clarify the details of distribution patterns of spinal epidural fluid and to establish it as measure of spontaneous intracranial hypotension (SIH) syndrome diagnosis. Magnetic resonance imaging findings of the spine were analyzed in 37 patients, 24 women and 13 men (mean age 46.3 years), with SIH. Detection rate, thickness and patterns of the fluid collection were evaluated at every vertebral level. Follow-up spinal MRI findings were also analyzed for changes in epidural fluid collection and association with clinical symptoms...

KEY POINTS: The brain is vulnerable to damage from too little or too much blood flow. A physiological mechanism called cerebral autoregulation (CA) exists to maintain stable blood flow even if cerebral perfusion pressure (CPP) is changing. A robust method for assessing CA is not yet available. There are still some problems with the traditional measure, the pressure reactivity index (PRx). We introduced a new method, wavelet transform method (wPRx) to assess CA using data from two sets of controlled hypotension experiments in piglets: One set with artificially manipulated ABP oscillations; the other group were spontaneous ABP waves...

A 34-year-old woman came to the emergency room complaining of a severe orthostatic headache. Results of a cerebrospinal fluid tap and brain computed tomography were normal. Based on her history and symptoms, she was found to have spontaneous intracranial hypotension. She was hospitalized and her symptoms improved with conservative treatment. On the next day, her headache suddenly worsened. Cisternography was performed to confirm the diagnosis and determine the spinal level of her cerebrospinal fluid leak. It revealed multiple cerebrospinal fluid leaks in the lumbar and upper thoracic regions...

BACKGROUND: Spontaneous intracranial hypotension (SIH) is caused by cerebrospinal fluid (CSF) leakage. Definitive diagnosis can be difficult by clinical examinations and imaging studies. METHODS: SIH was diagnosed with the following criteria: (i) evidence of CSF leakage by cranial magnetic resonance imaging (MRI) findings of intracranial hypotension and/or low CSF opening pressure; (ii) no recent history of dural puncture. We quantified CSF proteins by ELISA or Western blotting...

Spontaneous intracranial hypotension (SIH) is an uncommon headache etiology, typically attributable to an unprovoked occult spinal CSF leak. Although frequently benign, serious complications may occur, including cerebral venous thrombosis (CVT). The objective of this study was to examine a highly complicated case of CVT attributable to SIH as a lens for understanding the heterogeneous literature on this rare complication, and to provide useful, evidence-based, preliminary clinical recommendations. A 43-year-old man presented with 1 week of headache, dizziness, and nausea, which precipitously evolved to hemiplegia...

BACKGROUND: Spontaneous epidural hemorrhage (EDH) is a rare occurrence that may be caused by vascular anomalies, infections, coagulopathies, or tumors. Spontaneous EDH occurring in patients without specific underlying disease has been reported only as intraspinal lesion but has never been demonstrated in the intracranial area. This study presents a 19-year-old patient with repeated spontaneous intracranial EDH caused twice by hysterical crying. CASE DESCRIPTION: The patient had spontaneous left frontal EDH after hysterical crying...

Spontaneous intracranial hypotension (SIH) is a rare and potentially serious condition in childhood. Cerebrospinal fluid (CSF) volume depletion is thought to be the main causative feature for intracranial hypotension, results from spontaneous CSF leak, often at the spine level. SIH is increasingly diagnosed in clinical practice, although it manifests into a variegated symptomatology. Indeed, downward displacement of the brain, sometimes mimicking a Chiari I malformation, but concomitant presentation of these syndromes has rarely been reported...

Cerebrospinal fluid leakage can develop due to traffic trauma or lumbar puncture; however, in many cases, it develops spontaneously without any obvious cause. This report describes a case of cerebrospinal fluid leakage caused by bowling activity. A 57-year-old woman adjusted her bowling form, which led to the development of an orthostatic headache and double vision. Cerebrospinal fluid leakage and right abducens nerve palsy was diagnosed, which was resistant to conservative treatment. An epidural blood patch was performed, leading to an improvement in the headache and abducens nerve palsy...

BACKGROUND: Spontaneous intracranial hypotension (SIH) is often misdiagnosed, and can lead to severe complications. Conventional MR sequences show a limited ability to aid in this diagnosis. MR-based intracranial pressure (MR-ICP) may be able to detect changes of intracranial elastance and pressure. PURPOSE: To determine whether MR-ICP is able to differentiate SIH patients from normal subjects, improve diagnostic sensitivity, and provide an insight into the pathophysiology...

Ossification of the ligament flavum in the thoracic spine is an uncommon radiological finding in the Western population but can present with back pain, varying degrees of myelopathy, and even paraplegia on occasion. The authors here present the case of a 50-year-old woman with a history of progressive back pain and symptoms of spontaneous intracranial hypotension who was found to have an ossified ligamentum flavum of the thoracic spine resulting in a dural erosion cerebrospinal fluid leak. Surgery involved removal of the ossified ligament flavum at T10-11, facetectomy, ligation of the nerve root, and primary closure of the dura, which resulted in complete resolution of the patient's symptoms...

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...
