Spontaneous intracranial hypotension is an increasingly recognized disorder, often, although not always, characterized by the triad of low-opening cerebrospinal fluid pressure on lumbar puncture, postural headache, and diffuse parenchymal meningeal enhancement on magnetic resonance imaging of the head. We describe an unusual case of a patient with spontaneous intracranial hypotension presenting with postural headache and tinnitus, aggravated at high altitudes.  相似文献

Background and Objective.— The occurrence of cerebral venous thrombosis has been reported among patients with spontaneous intracranial hypotension, but a causal relationship has not been clearly established. We reviewed our experience with spontaneous intracranial hypotension and cerebral venous thrombosis and we reviewed the relevant literature to evaluate the relationship between these 2 entities. Methods.— We reviewed the medical records and imaging studies of a consecutive group of patients with spontaneous intracranial hypotension evaluated at a tertiary care center between 1/1/2001 and 12/31/2007. The main search strategy was a systemic review of journal articles in MEDLINE (1966 to January 2008). Results.— Among 141 patients with spontaneous intracranial hypotension, 3 (2.1%) were also diagnosed with cerebral venous thrombosis. Among these 3 patients and the 17 reported in the literature there were 11 men and 9 women with a mean age of 39.5 years. Radiographic or clinical evidence for spontaneous intracranial hypotension preceding cerebral venous thrombosis was found in most patients, while there was no evidence for cerebral venous thrombosis preceding spontaneous intracranial hypotension in any patient. Eight (40%) of the 20 patients were found to have a change in their headache pattern believed to be due to the development of cerebral venous thrombosis. Complications of cerebral venous thrombosis, eg, cerebral venous infarction, occurred in 8 patients (40%). Conclusions.— Spontaneous intracranial hypotension is a risk factor for cerebral venous thrombosis, but cerebral venous thrombosis is found in only about 2% of patients with spontaneous intracranial hypotension. A change in headache pattern is not a reliable predictor of the development of cerebral venous thrombosis in patients with spontaneous intracranial hypotension.  相似文献

We report a case of spontaneous intracranial hypotension due to a cerebrospinal fluid leak at the C2 level, which was successfully treated by epidural fibrin glue patching. Epidural blood patching was performed twice, first with 6 mL of autologous blood and then with 10 mL, but the intracranial hypotension was unresponsive. Although successful treatment of postdural puncture headache and persistent leak after intrathecal catheterization by epidural patching with fibrin glue has been reported, fibrin glue has not been previously applied in spontaneous intracranial hypotension. Our observation suggests that epidural patching with fibrin glue should be considered in patients with spontaneous intracranial hypotension, if epidural blood patching fails to resolve the symptoms.  相似文献

Orthostatic headaches are the hallmark of spontaneous intracranial hypotension, but MRIs are traditionally obtained in the supine position. We investigated the utility of upright MRI of the brain in 6 patients with spontaneous intracranial hypotension. No discernable differences were noted between the supine and upright images.  相似文献

BACKGROUND: Some patients with spontaneous intracranial hypotension (SIH) often do not demonstrate typical orthostatic headache, which is contrary to the typical SIH syndrome. They usually have an obscure and intermittent headache, regardless of their positional change. OBJECT: The objective of this study is to investigate the clinical course of atypical SIH that manifests with diffuse pachymeningeal enhancement, but no orthostatic headaches. METHODS: Between January 1997 and December 2005, we observed a total of 6 patients who revealed atypical presentations including nonpostural headaches and normal cerebrospinal fluid (CSF) pressure, despite the diffuse pachymeningeal enhancement seen on their MR images. For a comparison of the clinical features and the disease course, 13 other SIH patients with typical clinical manifestations were selected as a control group. RESULTS: Cerebrospinal fluid leakage sites were confirmed in only one patient through a variety of diagnostic tools; in contrast, definite focal CSF leakage sites were found in 12 of 13 patients with typical SIH. The 6 atypical SIH patients were treated with conservative treatment, including strict bed rest and intravenous hydration for 2 to 3 weeks. After a mean follow-up of 12 months, their headaches were gradually relieved after 2 to 3 weeks of conservative treatment only. CONCLUSIONS: All SIHs do not necessarily show the typical clinical manifestations. The atypical finding of SIH such as nonorthostatic headache or normal CSF pressure may be the result of a normal physiologic response to the typical SIH as a compensatory reaction. Therefore, when faced with patients showing findings compatible with SIH on the brain MR images, regardless of nonpostural headache, atypical SIH should be suspected.  相似文献

Cerebral vein thrombosis (CVT) is a rare complication of spontaneous intracranial hypotension (SIH). When to suspect a thrombotic disorder during the course of intracranial hypotension is not fully elucidated. A 48‐year‐old woman was admitted because of SIH with no signs of CVT on neuroimaging. The occurrence of diplopia and blurred vision 12 days later led to the performance of further investigations, which revealed thrombosis of the left lateral sinus, in the absence of variations in the headache characteristics. Among the other 4 cases of SIH clearly preceding the occurrence of CVT reported so far, only one had a change in the headache pattern related to CVT development. Although a change in the characteristics of headache is considered a marker of CVT in patients with SIH, this is not invariably part of the clinical scenario. Any new neurologic finding on exam in the disease course should raise a suspicion of venous thrombosis, thus prompting further specific investigations.  相似文献

Spontaneous intracranial hypotension is considered a rare disorder. We conducted a study on the frequency of spontaneous intracranial hypotension in the emergency department (ED). We identified patients with spontaneous intracranial hypotension evaluated in the ED of a large urban hospital between 1 January 2003 and 31 December 2006. For comparison, we also identified all patients with spontaneous subarachnoid haemorrhage (SAH). Eleven patients with previously undiagnosed spontaneous intracranial hypotension were evaluated in the ED during the four-year time period. All patients presented with positional headaches and the duration of symptoms varied from one day to three months. None of the patients were correctly diagnosed with spontaneous intracranial hypotension in the ED. During the same time period, 23 patients with aneurysmal SAH were evaluated. Spontaneous intracranial hypotension is more common than previously appreciated and the diagnosis in the ED remains problematic.  相似文献

We applied the recent International Headache Society (IHS) criteria for headache related to spontaneous intracranial hypotension (SIH) to 90 consecutive patients with a final diagnosis of SIH confirmed by cerebral magnetic resonance imaging with contrast. Orthostatic headache (developing within 2 h of standing or sitting up) was present in 67 patients (75%) but appeared within 15 min after standing or sitting—as required by point A of the criteria—in only 53 (59%). Forty-four (49%) patients did not satisfy point A, including 22 (24%) with non-orthostatic headache and 14 (16%) with headache developing ≥ 15 min after standing or sitting up; 80 (89%) did not satisfy point D. Only three (3%) patients had headache fully satisfying the IHS criteria. These findings indicate that the current IHS criteria do not capture most patients with SIH-associated headache. Excluding the requirement for response to epidural blood patch (criterion D) and considering headaches appearing within 2 h of sitting or standing up would capture more patients.  相似文献

Background and Objective.— Spontaneous intracranial hypotension has become a well-described cause of headache particularly among young and middle-aged individuals. Treatment of the underlying spinal cerebrospinal fluid (CSF) leak is effective in relieving symptoms in the vast majority of patients but symptoms may become refractory. The author describes a novel surgical technique to treat intractable spontaneous intracranial hypotension.
Methods.— A lumbar laminectomy is performed, a strip of dura is resected, and the dural defect is closed. The resulting decrease in lumbar CSF volume is believed to increase intracranial CSF volume and pressure.
Results.— The technique was utilized in a patient who suffered with intractable positional headaches because of a spinal CSF leak for 6 years in spite of numerous surgical and nonsurgical therapies. Significant improvement of symptoms was sustained during a 1-year period of follow-up.
Conclusion.— Dural reduction surgery may be considered in carefully selected patients with intracranial hypotension.  相似文献

Filum ependymoma mimicking spontaneous intracranial hypotension   总被引:2,自引:0,他引:2  
Schievink WI  Akopov SE 《Headache》2005,45(5):607-609
A 34-year-old man with a 2-week history of orthostatic headaches and a "dry tap" at lumbar puncture was found to have a lumbar intradural mass on magnetic resonance imaging (MRI) examination. A myxopapillary ependymoma was resected and the patient's headache completely resolved. The combination of spontaneous orthostatic headaches and a "dry tap" at the time of lumbar puncture does not always indicate the presence of a spontaneous cerebrospinal fluid (CSF) leak and intracranial hypotension.  相似文献

A 48-year-old slender woman presented with a rare case of spontaneous intracranial hypotension syndrome manifesting as patulous Eustachian tube. The patient complained of sudden onset of ear fullness and nasal voice as well as typical orthostatic headache. Patulous Eustachian tube was identified by observation of synchronous movement of the tympanic membrane with respiration and swallowing. The diagnosis of spontaneous intracranial hypotension was confirmed by negative cerebrospinal fluid pressure, and typical magnetic resonance imaging and radioisotope cisternography findings. All symptoms completely resolved within a few days after epidural blood patch treatment. Changes in the venous blood distribution led by collapse of the dural sac of the cervical spine in the standing position presumably caused decreased size of the pterygoid venous plexus around the Eustachian tube.  相似文献

Intracranial hypotension: the nonspecific nature of MRI findings   总被引:1,自引:0,他引:1  
We present three patients who complained of postural headache related to different types of intracranial hypotension: spontaneous or primary, and secondary, but presenting the same findings on brain magnetic resonance imaging. Diffuse pachymeningeal gadolinium enhancement supports the belief that the enhancement is a nonspecific meningeal reaction to low pressure.  相似文献

Lumbar puncture is crucial in two distinct clinical situations in the diagnosis of the headache patient. The first is the patient who is suspected of having a symptomatic headache; the second is the patient with a chronic intractable or atypical headache disorder. This review discusses the usefulness of the lumbar puncture in the diagnosis of headache secondary to subarachnoid hemorrhage, meningitis, and intracranial hypotension and hypertension. The value of lumbar puncture in the presence of a normal CT/MRI scan is discussed.  相似文献

Intracranial hypotension is typically manifested by orthostatic headache. The most frequent underlying factor is cerebrospinal fluid leakage. It has been suggested that dural structural weakness in some connective tissue diseases may be responsible for dural tears and diverticula and consequently leakage. We present a case of spontaneous intracranial hypotension associated with Marfan syndrome and autosomal dominant polycystic kidney disease. The patient was treated successfully with epidural autologous blood patch. Dural involvements of these hereditary connective tissue diseases are also discussed.  相似文献

Spontaneous intracranial hypotension (SIH) is typically characterized by orthostatic headache; however, various atypical manifestations of SIH have been reported recently. We report here the case of a 46‐year‐old man with headache secondary to SIH, which was nonorthostatic, triggered only when the patient shook his head. We suggest that SIH should be suspected in patients with headache induced by head‐shaking, even without orthostatic features, especially when the headache is accompanied by other symptoms commonly associated with SIH.  相似文献

Two patients with spontaneous intracranial hypotension (SIH) subsequently developed cerebral venous thrombosis (CVT) when their headache lost its distinctive orthostatic characteristic. In addition to typical MRI features of tonsillar descent, subdural fluid collections, and diffuse pachymeningeal enhancement, hyperintense thrombi were detected in the dural sinuses, and filling defects on magnetic resonance venography. Knowledge of the typical neuroimaging features of SIH and CVT and change in headache characteristics are important for prompt diagnosis and treatment.  相似文献

Postural headache in a patient with Marfan's syndrome   总被引:2,自引:0,他引:2  
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 unrecognized trauma.  相似文献
