OBJECTIVE a case is described of a spontaneously occurring cerebrospinal fluid collection in the ventral cervical spine which caused radiculopathy and spontaneous intracranial hypotension. CASE a sixty eight year old Caucasian man presented with a 2 year history of proximal upper limb weakness with a his-tory of trivial cervical trauma many years previously. METHODS the patient was investig...

OBJECTIVE To describe a case of spontaneous intracranial hypotension with a previously unreported constellation of presenting features. DESIGN Case report. SETTING Tertiary care center. MAIN OUTCOME AND RESULTS We describe a patient with intracranial hypotension who presented with a parkinsonian syndrome and later development of ataxia and prominent bulbar symptomatology. Headache was not...

The effects of arterial hypotension and a raised intracranial pressure on cerebral blood flow (CBF) have been investigated in an animal model of hepatic failure. Arterial hypotension was associated with a fall in CBF in the animals with liver failure but not in the controls. Significant differences in mean CBF between the two groups of animals could be demonstrated when the systolic blood press...

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...

BACKGROUND AND PURPOSE Comprehensive diagnostic criteria encompassing the varied clinical and radiographic manifestations of spontaneous intracranial hypotension are not available. Therefore, we propose a new set of diagnostic criteria. MATERIALS AND METHODS The diagnostic criteria are based on results of brain and spine imaging, clinical manifestations, results of lumbar puncture, and respon...

The most common causes of intracranial hypotension include persistent cerebrospinal fluid (CSF) leakage from lumbar puncture, spontaneous CSF leakage, or excessive CSF drainage. Spontaneous intracranial hypotension (SIH) is defined as a syndrome of reduced CSF pressure that occurs in the absence of dural puncture, surgery, or trauma. The pathogenesis is generally thought to be an occult leak of...

Intracranial hypotension (IH) can occur following lumbar drainage for clipping of an intracranial aneurysm. We observed 3 cases of IH, which were all successfully treated by epidural blood patch (EBP). Herein, the authors report our cases.

INTRODUCTION Headache is a common presenting complaint and has a wide differential diagnosis. Clinicians need to be alert to clues that may suggest an underlying secondary aetiology. We describe a novel case of headache secondary to intracranial hypotension which was precipitated by the rupture of a spinal arachnoid cyst. CASE REPORT A 51-year-old Indian female presented with sudden onset sev...

Spontaneous intracranial hypotension (SIH) is a syndrome in which a cerebrospinal fluid leak occurs within the spinal axis, and may lead to a constellation of neurological symptoms. A postural or orthostatic headache is the most common of these symptoms1. Spontaneous intracranial hypotension was first recognized by Georg Schaltenbrand in the 1930s. Many terms have been used to describe the cond...

Symptomatic overdrainage of cerebrospinal fluid (CSF) can be seen in shunted hydrocephalus patients and in non-shunted patients with spontaneous intracranial hypotension (SIH). In these patients, intracranial pressure (ICP) monitoring often reveals negative static ICP, while it is less understood how the pulsatile ICP (cardiac induced ICP waves) is affected. This latter aspect is addressed in t...
