World Arnold Chiari Malformation Association Acquired vs. Congenital 1. J Neurosurg 1995 Sep;83(3):556-558 Acquired Chiari I malformation and syringomyelia associated with bilateral chronic subdural hematoma. Case report.Morioka T, Shono T, Nishio S, Yoshida K, Hasuo K, Fukui M Department of Neurosurgery, Kyushu University, Fukuoka, Japan. The authors report a case of bilateral chronic subdural hematoma in a 25-year-old woman who had occipital and neck pain. Magnetic resonance imaging revealed progressive caudal descent of the cerebellar tonsils (acquired Chiari I malformation) and a large eccentric syrinx in the spinal cord from the C3-T7 levels. Spontaneous disappearance of the chronic subdural hematomas resulted in radiographic resolution of both lesions, as well as clinical improvement. Theories of syringomyelia formation, the relationship to acquired Chiari I malformation, and the implications of this case are discussed. 2.

Aoki, T. Sakai, A. Oikawa Department of Neurosurgery, Tokyo Metropolitan Ohkubo Hospital, Tokyo, Japan Summary A 55-year-old woman presented with headache which was characterized by aggravation in the upright position and relief in recumbency. Although intracranial hypotension syndrome was condidered to be the most-likely possible entity, computed tomography (CT) scans demonstrated subdural fluid collections associated with findings reminiscent of transtentorial herniation. Because of these CT features, cerebrospinal fluid pressure measurement by a lumbar puncture was not performed. Instead, as an alternative method, she underwent percutaneous subdural tapping, which failed to obtain spontaneous drainage of liquid haematoma, indicating intracranial hypotension. In addition, gadolinium-enhanced magnetic resonance imaging study performed later supported the diagnosis of spontaneous intracranial hypotension. Thus, the usefulness and safety of percutaneous subdural tapping for the diagnosis of spontaneous intracranial hypotension is stressed.

Treatment Depending on the cause of the leak, many cases resolve spontaneously after a few days. Complete bed rest for several days is usually recommended. Headache may be treated with pain relievers and fluids. If the headache persists longer than a week after a lumbar puncture, a blood patch procedure may be done to block the hole that may be leaking fluid. In most cases, this resolves the symptoms. If symptoms of infection occur ( fever , chills, change in mental status), antibiotic therapy is required.

Slit Ventricle Syndrome Definition slit ventricle syndrome has been applied to a small subset of these shunt-dependent children who develop disabling chronic or recurring headaches associated with signs and symptoms of increased ICP and persistant small or slit-like ventricles by CT. Pathology Pathogenesis 1. One hypothesis is that chronic overdrainage in the upright position creates a suction-induced collapse of the ventricular wall around the ventricular catheter, causing recurrent elevations of ICP, and ultimately complete shunt obstruction. The CT scan shows increases in ventricular volume during the episodes of severe headache. 2. Failure of the ventricles to enlarge may be due to an increase in CSF outflow resistance and altered intracranial compliance secondary to brain stiffness from periventricular gliosis. 3. A partially obstructed ventricular catheter may limit the ability to increase CSF drainage rate in response to increases in intracranial volume, and thus precipitate the pressure wave; this would explain the observation that in some situations a shunt revision is curative even with a normal preoperative shunt study. Clinical Features headaches that are chronic intermittent , and recurring . Headaches exacerbated by activity and upright position may be suffering from chronic intracranial hypotension. Imaging Treatment and Results Medical steroids and acetazolamide may significantly relieve the headache.

The patient was a 28 year-old female and was admitted to our hospital with orthostatic headache and back pain. Spinal puncture revealed low liquor pressure. Myelogram disclosed narrowed dural tube and emphasized outline of cauda equina and spinal cord. CTM showed an enhanced area in the posterior site of dural tube. Her complaints were gradually relieved without specific treatment. We also performed gadolinium enhanced MRI which revealed meningeal enhancement and dilatation of internal vertebral venous plexus. These typical radiological findings enabled us to diagnose this case as spontaneous intracranial hypotension.

CSF Leaks Last edited: 11/2002 by Timothy C. Hain, MD , Chicago IL. Click here to return to index Please read our Cerebrospinal fluid depetion may be caused by a leak or a shunt. Symptoms commonly include headaches, which are more severe in the upright position and are alleviated by supine positioning. There may also be nausea and tinnitus. Horizontal diplopia, change in hearing, tinnitus, blurring of vision, facial numbness and upper limb radicular symptoms may occur. These symptoms are rather nonspecific as they are commonly encountered in migraine and post-traumatic headache. Cognitive decline has also been reported (Hong et al, 2002; Pleasure et al, 1998). The leaks are typically at the level of the spine, particularly the thoracic spine and cervicothoracic junction. Sometimes they are unintentional consequences of an overdraining CSF shunt, placed for CSF hypertension. CSF leaks can also occur in the nose after trauma or surgery, and following diagnostic or therapeutic lumbar puncture. Spontaneous leaks from the nose are uncommon (1/26 in Mokri, 1997). Speculatively, it would seem possible that CSF leaks might occur after whiplash injury , as frequently there are persistent similar symptoms without findings on other studies. At this writing however (2002), almost nothing has been published regarding this possibility.

35. Kaj-e enhancement at MR in patients with post lumbar puncture headache is caused bymeningeal vein widening which in turn is caused by intracranial hypotension. http://www.ki.se/cns/news/kaj-e.html

News from Editor: Previous articles Meningeal enhancement at MR in patients with post lumbar puncture headache is caused by meningeal vein widening which in turn is caused by intracranial hypotension After lumbar puncture many patients suffer from a more or less severe headache lasting from weeks to months. The reason for post lumbar puncture headache (PLPH) is believed to be leakage of cerebrospinal fluid (CSF). Ass. Prof. Jan Hannerz, Section of Neurology, Prof. Kaj Ericson Lumbar puncture may cause a rift in the dural and arachnoidal membranes. This results in CSF leakage which then causes a reduced intracranial pressure. PLPH is a consequence of the reduced pressure. The intracranial meningeal veins are dilated as a result of the reduced intracranial pressure, and this results in increased enhancement. The enhancement may be subtle and noticed only when compared with MR studies after the PLPH has subsided. Patients with more marked enhancement after lumbar puncture may be suspected to have a longer lasting headache. Awareness of these facts are important since meningeal enhancement may suggest a serious disease such as meningitis or meningeal carcinomatosis. Thus, if conspicuous meningeal enhancement is found at MR it should be explored if the patient has had a recent lumbar puncture and is suffering from PLPH. If not, other causes for the enhancement should be investigated. One such cause may be spontaneous intermittent or continuous leakage of CSF; such leakage may be shown by MR measurements of the CSF flow. These patients may be candidates for treatment with blood patch.

Correspondence: Prof. Jeffrey S. Kroin, Rush-Presbyterian-Luke's Medical Center, Chicago January 2003 Dear Professor Jeffrey S.Kroin and Colleagues, I have read your article [1] with great attention. Your valuable experimental evidence on a rat model is supporting my hypothesis presented on web page http://www.med-lavrencic.si/raziskava.htm and my opinions expressed on web page http://www.med-lavrencic.si/correspondence.htm. I believe that the intracraniovertebral volumes' homeostatic equilibrium i.e. volumes' balance is relatively stable regardless to different body postures i.e. standing up, lying or hanging with head upside down. The relative hydrostatic pressure difference among CSF pressures and opposite hydrostatic pressures at CSF drainage paths remains relatively constant during different body postures while passively floating CSF formation/removal homeostatic equilibrium along the CSF formation curve supports this stable volumes' balance at the expense of CSF flow: when standing up it is increased and when hanging down it is decreased. What is your opinion about this?

The Intracraniovertebral Volumes, the Cerebrospinal Fluid Flow and the Cerebrospinal Fluid Pressure, Their Homeostasis and Its Physical Regulation Darko D. Lavrencic, MD darko.lavrencic@siol.net Slovenia Preface. Summary. Physiological and pathophysiological processes in the intracraniovertebral space are specific because of its rigid and constant volume (Monro-Kellie doctrine). The hypothesis presents how the homeostasis of the intracraniovertebral compartments' volumes, cerebrospinal fluid (CSF) flow and CSF pressure is physically regulated. The hypothesis takes into account the quantitative and qualitative relations regulating CSF formation and CSF removal on which the homeostasis is based. top Introduction Monro found in 1783, during studying brain blood circulation, that the processes in intracranial space are specific due to the constant volume of the skull. None of the contained masses can be compressed and one of them can be increased, only if another one is decreased. This occurs when the ossification of the cranial sutures is so strong that it resists any increase of intracranial pressure. Monro-Kellie doctrine includes 3 compartments' volumes: (1) brain and medulla spinalis with meninges, (2) cerebrospinal blood vessels with blood, (3) CSF space. Dural sac is elastic. It can be distended or collapsed. The spinal extradural space, which contains soft tissues and veins plexuses adapts to the changes of dural sac. The author of this text regards this spinal extradural space and intracranial venous sinuses as compartment IV. By the addition of compartment IV, Monro-Kellie doctrine becomes re-established in wider sense.
