  • Spontaneous CSF Leaks Low CSF Volume Syndromes
    Spontaneous CSF Leaks Low CSF Volume Syndromes Bahram Mokri, MD KEYWORDS Spontaneous CSF leak Spontaneous intracranial hypotension (SIH) CSF hypovolemia Orthostatic headaches Diffuse patchy meningeal enhancement Acquired Chiari malformation Epidural blood patch Radioisotope cisternography KEY POINTS Spontaneous intracranial hypotension nearly always results from spontaneous cerebro- spinal fluid (CSF) leaks, typically at the spine level and only rarely from the skull base. The triad of orthostatic headaches, diffuse patchy meningeal enhancement, and low CSF pressure, although a diagnostic hallmark, may or may not be encountered because the variability in clinical presentations, imaging observations, and CSF findings is indeed substantial. The core pathogenetic factor is a decreased volume of CSF rather than its pressure. The anatomy of the leak may be complex. A preexisting dural weakness, usually in connection with an abnormality of the connective tissue matrix sometimes along with triv- ial traumas, may play an etiologic role. Slow-flow and fast-flow CSF leaks each present challenges on locating the actual site of the leak. Epidural blood patch (EBP) has emerged as the treatment of choice when conservative measures have failed. However, expect considerable variability in response to this treat- ment, and recall that the efficacy of EBP in spontaneous CSF leaks is substantially less than its efficacy in postlumbar puncture leaks. Surgery may be helpful in well-selected cases, when less invasive measures have failed and when the site of the leak has been definitely identified. INTRODUCTION About 2 decades ago, the first report on pachymeningeal gadolinium enhancement in spontaneous intracranial hypotension (SIH) appeared in the literature.1 This relatively short interval has witnessed enormous progress while a much larger number of pa- tients are now identified and a far broader clinical spectrum is recognized.2 Funding Source: None.

  • Cerebrospinal Fluid Dissemination and Neoplastic Meningitis in Primary Brain Tumors Sajeel Chowdhary, MD, Sherri Damlo, and Marc C
    Special Report Cerebrospinal Fluid Dissemination and Neoplastic Meningitis in Primary Brain Tumors Sajeel Chowdhary, MD, Sherri Damlo, and Marc C. Chamberlain, MD Background: Neoplastic meningitis, also known as leptomeningeal disease, affects the entire neuraxis. The clinical manifestations of the disease may affect the cranial nerves, cerebral hemispheres, or the spine. Because of the extent of disease involvement, treatment options and disease staging should involve all compartments of the cerebrospinal fluid (CSF) and subarachnoid space. Few studies of patients with primary brain tumors have specifically addressed treatment for the secondary complication of neoplastic meningitis. Therapy for neoplastic meningitis is palliative in nature and, rarely, may have a curative intent. Methods: A review of the medical literature pertinent to neoplastic meningitis in primary brain tumors was performed. The complication of neoplastic meningitis is described in detail for the various types of primary brain tumors. Results: Treatment of neoplastic meningitis is complicated because determining who should receive ag- gressive, central nervous system (CNS)–directed therapy is difficult. In general, the therapeutic response of neoplastic meningitis is a function of CSF cytology and, secondarily, of the clinical improvement in neuro- logical manifestations related to the disease. CSF cytology may manifest a rostrocaudal disassociation; thus, consecutive, negative findings require that both lumbar and ventricular cytological testing are performed to confirm the complete response. Based on data from several prospective, randomized trials extrapolated to primary brain tumors, the median rate of survival for neoplastic meningitis is several months. Oftentimes, therapy directed at palliation may improve quality of life by protecting patients from experiencing continued neurological deterioration.

  • Cerebral Venous Overdrainage: an Under-Recognized Complication of Cerebrospinal Fluid Diversion
    NEUROSURGICAL FOCUS Neurosurg Focus 41 (3):E9, 2016 Cerebral venous overdrainage: an under-recognized complication of cerebrospinal fluid diversion Kaveh Barami, MD, PhD Department of Neurosurgery, Kaiser Permanente Northern California, Sacramento, California Understanding the altered physiology following cerebrospinal fluid (CSF) diversion in the setting of adult hydrocephalus is important for optimizing patient care and avoiding complications. There is mounting evidence that the cerebral venous system plays a major role in intracranial pressure (ICP) dynamics especially when one takes into account the effects of postural changes, atmospheric pressure, and gravity on the craniospinal axis as a whole. An evolved mechanism acting at the cortical bridging veins, known as the “Starling resistor,” prevents overdrainage of cranial venous blood with upright positioning. This protective mechanism can become nonfunctional after CSF diversion, which can result in posture- related cerebral venous overdrainage through the cranial venous outflow tracts, leading to pathological states. This review article summarizes the relevant anatomical and physiological bases of the relationship between the craniospinal venous and CSF compartments and surveys complications that may be explained by the cerebral venous overdrainage phenomenon. It is hoped that this article adds a new dimension to our therapeutic methods, stimulates further research into this field, and ultimately improves our care of these patients. http://thejns.org/doi/abs/10.3171/2016.6.FOCUS16172 KEY WORDS cerebrospinal fluid diversion; hydrocephalus; posture; shunt; Starling resistor; cerebral venous overdrainage HE intimate relationship between cerebral venous ent pressure (CSF in the subarachnoid space) all contained and cerebrospinal fluid (CSF) compartments is in a rigid box, such as the skull in the hydraulic model increasingly recognized as an important aspect of shown in Fig.
