CSF-venous fistula is a recently reported cause of spontaneous intracranial hypotension that may occur in the absence of myelographic evidence of CSF leak. Information about this entity is currently very limited, but it is of potential importance given the large percentage of cases of spontaneous intracranial hypotension associated with negative myelography findings. We report 3 additional case...

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...

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...

INTRODUCTION Spontaneous intracranial hypotension is an infrequent cause of secondary headache due to cerebrospinal fluid (CSF) hypovolemia. OBJECTIVE To describe a case of headache revealing spontaneous intracranial hypotension complicated by subdural hematoma following lumbar puncture. OBSERVATION A 34-year-old man presented with acute postural headache. The first cerebral computed tomogr...

A 43-year-old man presented with a nontraumatic orthostatic headache, spatial disorientation, and visual hallucinations ("colored flames"). General and neurologic examination were normal. Turbo spin echo T2-weighted MRI showed bilateral subdural fluid collection and venous sinus engorgement (figure, A), suggesting spontaneous intracranial hypotension (SIH). Two subdural hematomas were also foun...

PURPOSE To describe a case of superior sagittal sinus thrombosis in the puerperal period and the difficulties encountered in the diagnosis and management. CLINICAL FEATURES A 29-yr-old multiparous woman presented with a postural headache four weeks after a normal pregnancy and vigorous delivery. Initial presentation suggested spontaneous intracranial hypotension (SIH) since there was no histo...

Spontaneous intracranial hypotension (SIH) is characterized by postural headache because of low cerebrospinal fluid (CSF) pressure. Brain magnetic resonance imaging (MRI) and radioisotope (RI) cisternography can be used to identify the site of a CSF leakage. Although autologous epidural blood patch (EBP) is a very effective treatment modality, some patients require a repeat autologous EBP. We i...

CONTEXT Spontaneous intracranial hypotension is caused by spontaneous spinal cerebrospinal fluid (CSF) leaks and is known for causing orthostatic headaches. It is an important cause of new headaches in young and middle-aged individuals, but initial misdiagnosis is common. OBJECTIVE To summarize existing evidence regarding the epidemiology, pathophysiology, diagnosis, and management of spontan...
