BACKGROUND AND PURPOSE We evaluated the use of MR cisternography after intrathecal administration of gadopentetate dimeglumine to detect the presence and localization of CSF leaks in 19 patients diagnosed with spontaneous intracranial hypotension syndrome according to the criteria of International Headache Society. MATERIALS AND METHODS Lumbar puncture with an injection of 0.5 mL of gadopente...

INTRODUCTION The syndrome of spontaneous intracranial hypotension has been increasingly diagnosed since its discovery through magnetic resonance imaging (MRI). It is a rare syndrome that is due to the leakage of cerebrospinal fluid (CSF) from a tear in the dura and can occur at any age, even among adolescents, but is most frequently seen among females in late middle age. CASE PRESENTATION Her...

Spontaneous intracranial hypotension (SIH) is a syndrome in which hypovolemia of the cerebrospinal fluid (CSF) results in various symptoms. Although its prognosis is usually benign, cases with a rapid neurologic deterioration resulting in an altered mental status have been reported. One of the characteristic radiographic findings in such cases is the presence of bilateral accumulation of subdur...

A 41-year-old man presented with progressive worsening of postural headache. Computed tomography (CT) showed bilateral subdural hematomas without prior history of trauma. The diagnosis was spontaneous intracranial hypotension (SIH). Conservative treatment with oral steroids failed to prevent gradual deterioration of the patient's consciousness. CT myelography revealed massive cerebrospinal flui...

BACKGROUND Spinal cerebrospinal fluid (CSF) leaks, which are considered a cause of intracranial hypotension, generally do not cause any local symptoms. Although symptoms are key elements for further evaluation, few studies have examined symptom predictors of intracranial hypotension. The aim of this study was to determine what symptoms are predictors of CSF leaks in patients suspected of intrac...

Granulocyte macrophage-colony stimulating factor (GM-CSF) has immuno-stimulatory effects. We hypothesized that GM-CSF plays an important role both in lipopolysaccharide (LPS)- and hemorrhage-induced acute lung injury (ALI). We also postulated that GM-CSF augments LPS-induced inflammation by priming neutrophils. ALI was induced in GM-CSF-/- or control C57BL mice either by LPS injection or by hem...

The effects of intravenous injection of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on circulating neutrophil numbers, pulmonary vascular permeability, and morphologic changes in the lung were examined in rabbits. Intravenous injection of rhG-CSF caused a rapid, profound neutropenia due to neutrophil sequestration primarily within capillaries but also in larger microvessel...

BACKGROUND AND PURPOSE The apolipoprotein E (APOE) epsilon4 allele has been associated with unfavorable outcome after subarachnoid hemorrhage (SAH), suggesting that apoE plays an important role in the response of the brain to SAH. We determined the concentration of apoE in the cerebrospinal fluid (CSF) of patients with SAH and a control group to test the hypothesis that alterations in CSF apoE ...

Intracranial hypotension syndrome (IHS) is generally caused by cerebrospinal fluid (CSF) leakage. Complications include bilateral subdural hygroma or haematoma and herniation of the cerebellar tonsils. Epidural blood patch (EBP) therapy is indicated if conservative treatment is ineffective. We reported the case of a 46-year-old man with a history of postural headache and dizziness. The patient ...
