Csf Leaks

✓ Spinal cerebrospinal fluid (CSF) leaks are often implicated as the cause of the syndrome of spontaneous intracranial hypotension, but they have rarely been demonstrated radiographically or surgically. The authors reviewed their experience with documented cases of spinal CSF leaks of spontaneous onset in 11 patients including their surgical observations in four of the patients. The mean age of the six women and five men included in the study was 38 years (range 22–51 years). All patients presented with a postural headache; however, most had additional symptoms, including nausea, emesis, sixth cranial-nerve paresis, or local back pain at the level of the CSF leak. All patients underwent indium-111 radionucleotide cisternography or computerized tomographic (CT) myelography. The location of the spontaneous CSF leak was in the cervical spine in two patients, the cervicothoracic junction in three patients, the thoracic spine in five patients, and the lumbar spine in one patient. The false negative rate for radionucleotide cisternography was high (30%). Subdural fluid collections, meningeal enhancement, and downward displacement of the cerebellum, resembling a Chiari I malformation, were commonly found on cranial imaging studies. In most patients, the symptoms resolved in response to supportive measures or an epidural blood patch. Leaking meningeal diverticula were found to be the cause of the CSF leak in four patients who underwent surgery. In three patients these diverticula could be ligated with good result but in one patient an extensive complex of meningeal diverticula was found to be inoperable. Two patients had an unusual body habitus and joint hypermobility, and two other patients had suffered a spontaneous retinal detachment at a young age. In conclusion, spontaneous spinal CSF leaks are uncommon, but they are increasingly recognized as a cause of spontaneous intracranial hypotension. Most spinal CSF leaks are located at the cervicothoracic junction or in the thoracic spine, and they may be associated with meningeal diverticula. The radiographic study of choice is CT myelography. The disease is usually self-limiting, but in selected cases our experience with surgical ligation of leaking meningeal diverticula has been satisfactory. An underlying connective tissue disorder may be present in some patients with a spontaneous spinal CSF leak.

Csf Leaks

Objective The objective of this report is to compare computed tomography (CT) and magnetic resonance (MR) myelography with radioisotope cisternography (RC) for detection of spinal cerebrospinal (CSF) leaks. Methods We retrospectively reviewed 12 spontaneous intracranial hypotension (SIH) patients; CT and RC were performed simultaneously. Three patients had MR myelography. Results CT and/or MR myelography identified CSF leaks in four of 12 patients. RC detected spinal leaks in all three patients confirmed by CT myelography; RC identified the CSF leak location in two of three cases, and these were due to osteophytic spicules and/or discs. RC showed only enlarged perineural activity. Only intrathecal gadolinium MR myelography clearly identified a slow leak from a perineural cyst. In eight remaining cases, the leak site was unknown; however, two of these showed indirect signs of CSF leak on RC. CSF slow leaks from perineural cysts were the most common presumed etiology; and the cysts were best visualized on myelography. Conclusion RC is comparable to CT myelography but has spatial limitations and should be limited to atypical cases.

Venous Fistula

Spontaneous CSF–venous fistulas may be present in up to one-fourth of patients with spontaneous intracranial hypotension. This is a recently discovered type of CSF leak, and much remains unknown about these fistulas. Spinal CSF–venous fistulas are usually seen in coexistence with a spinal meningeal diverticulum, suggesting the presence of an underlying structural dural weakness at the proximal portion of the fistula. The authors now report the presence of soft-tissue venous/venolymphatic malformations associated with spontaneous spinal CSF–venous fistulas in 2 patients with spontaneous intracranial hypotension, suggesting a role for distal venous pathology. In a third patient with spontaneous intracranial hypotension and a venolymphatic malformation, such a CSF–venous fistula is strongly suspected.

Abstract The hallmark symptom of spontaneous intracranial hypotension (SIH) is orthostatic headaches which manifests secondary to cerebrospinal fluid (CSF) hypovolaemia. Well-recognised aetiologies include trauma which includes procedures such as lumbar punctures and spinal surgery. More recently, structural defects such as bony osteophytes and calcified or herniated discs have been attributed to mechanically compromising dural integrity consequently resulting in CSF leak and symptom manifestation. A thorough literature review noted only a handful of such cases. We report the case of a thirty-two-year-old Asian female who presented with a one-month history of new-onset progressively worsening orthostatic headaches. Workup included MRI of the thoracic spine which revealed an epidural collection of CSF consequently prompting a dynamic CT-myelogram of the spine which not only helped to confirm severe cerebral hypotension but also suggested the underlying cause as being a dorsally projecting osteophyte-complex at level T2-3. Conservative and medical management including bed rest, analgesia, mechanical compression, and epidural blood patches failed to alleviate symptoms and a permanent surgical cure was eventually sought. The surgery involved T2-T3 laminectomy and osteophytectomy and at a 3-month follow-up, complete resolution of symptoms was noted.

Diffuse Pachymeningeal Enhancement

A 26-year-old man with Marfan's syndrome had postural headache. Brain MRI with gadolinium showed diffuse pachymeningeal enhancement. MRI myelography revealed bilateral multiple large meningeal diverticula at sacral nerve roots level. He was suspected to have spontaneous intracranial hypotension syndrome. Eight days later headache improved with bed rest and hydration. One month after the onset he was asymptomatic and 3 months later brain MRI showed no evidence of diffuse pachymeningeal enhancement. The 1-year follow-up revealed no neurological abnormalities. The intracranial hypotension syndrome likely resulted from a CSF leak from one of the meningeal diverticula. In conclusion patients with spinal meningeal diverticula (frequently seen in Marfan's syndrome) might be at increased risk of developing CSF leaks, possibly secondary to Valsalva maneuver or minor unrecognizedtrauma.

Csf Leaks

Object Spontaneous intracranial hypotension is an important cause of headaches and an underlying spinal CSF leak can be demonstrated in most patients. Whether CSF leaks at the level of the skull base can cause spontaneous intracranial hypotension remains a matter of controversy. The authors' aim was to examine the frequency of skull base CSF leaks as the cause of spontaneous intracranial hypotension. Methods Demographic, clinical, and radiological data were collected from a consecutive group of patients evaluated for spontaneous intracranial hypotension during a 9-year period. Results Among 273 patients who met the diagnostic criteria for spontaneous intracranial hypotension and 42 who did not, not a single instance of CSF leak at the skull base was encountered. Clear nasal drainage was reported by 41 patients, but a diagnosis of CSF rhinorrhea could not be established. Four patients underwent exploratory surgery for presumed CSF rhinorrhea. In addition, the authors treated 3 patients who had a postoperative CSF leak at the skull base following the resection of a cerebellopontine angle tumor and developed orthostatic headaches; spinal imaging, however, demonstrated the presence of a spinal source of CSF leakage in all 3 patients. Conclusions There is no evidence for an association between spontaneous intracranial hypotension and CSF leaks at the level of the skull base. Moreover, the authors' study suggests that a spinal source for CSF leakage should even be suspected in patients with orthostatic headaches who have a documented skull base CSF leak.

Subdural Bleeding

Subdural hematoma is a relatively common complication of long-term anticoagulation, particularly in the elderly. The combination of anticoagulation and cerebral cortical atrophy is believed to be sufficient to explain the subdural bleeding. The authors report a series of elderly patients who were on a regimen of anticoagulation and developed chronic subdural hematomas (SDHs) due to a spontaneous spinal CSF leak. They reviewed the medical records and imaging studies of a consecutive group of patients with spontaneous intracranial hypotension who were evaluated at Cedars-Sinai Medical Center. Among 141 patients with spontaneous spinal CSF leaks and spontaneous intracranial hypotension, 3 (2%) were taking anticoagulants at the time of onset of symptoms. The mean age of the 3 patients (1 woman and 2 men) was 74 years (range 68–86 years). All 3 patients had chronic SDHs measuring between 12 and 23 mm in maximal diameter. The SDHs resolved after treatment of the underlying spontaneous spinal CSF leak, and there was no need for hematoma evacuation. Epidural blood patches were used in 2 patients, and percutaneous placement of a fibrin sealant was used in 1 patient. The presence of an underlying spontaneous spinal CSF leak should be considered in patients with chronic SDHs, even among the elderly taking anticoagulants.

Background Spontaneous intracranial hypotension due to a spinal cerebrospinal fluid (CSF) leak has become a well-recognized cause of headaches. Recently, various unusual neurological syndromes have been described in such patients with chronic ventral CSF leaks, including superficial siderosis and an amyotrophic lateral sclerosis-like syndrome. The authors now report two patients with spontaneous intracranial hypotension due to a chronic ventral CSF leak who suffered a diffuse non-aneurysmal subarachnoid hemorrhage (SAH). Description of cases A 62-year-old woman underwent uneventful microsurgical repair of a ventral thoracic CSF leak that had been present for 13 years. Seventeen months after surgery, she was found unresponsive and CT showed a diffuse intracranial SAH. Cerebral angiography and spine and brain MRI did not reveal a source of the SAH. A 73-year-old woman was found unresponsive and CT showed a diffuse intracranial SAH. Cerebral angiography and brain MRI did not reveal a source of the SAH, although superficial siderosis was detected. Spine MRI showed a ventral thoracic CSF leak that by history had been present for 41 years. She underwent uneventful microsurgical repair of the CSF leak. Discussion The authors suggest that patients with a ventral spinal CSF leak of long duration may be at risk of diffuse non-aneurysmal SAH.

✓ Spontaneous intracranial hypotension due to a spinal cerebrospinal fluid (CSF) leak is a rare but increasingly recognized cause of postural headaches. The exact cause of these CSF leaks often remains unknown. The authors treated a 32-year-old man with a unique cause of spontaneous intracranial hypotension. He suffered an excruciating headache that was exacerbated by his being in an upright position. The results of four-vessel cerebral angiography were negative; however, magnetic resonance (MR) imaging of the brain revealed pachymeningeal enhancement and hindbrain herniation. A presumptive diagnosis of spontaneous intracranial hypotension was made. Myelography revealed extrathecal contrast material ventral to the cervical spinal cord as well as an unusual midline bone spur at C5–6. The patient's symptoms did not resolve with the application of epidural blood patches, and he subsequently underwent an anterior approach to the C5–6 spur. After discectomy, a slender bone spur that had pierced the thecal sac was found. After its removal, the dural rent was closed using two interrupted prolene sutures. The patient was discharged home 2 days later. On follow up his symptoms had resolved, and on MR imaging the pachymeningeal enhancement had resolved and the cerebellar herniation had improved slightly.
