BACKGROUND: Diagnosis of spontaneous intracranial hypotension (SIH) relies on the ability of medical staff to recognize cerebrospinal fluid (CSF) leakage at the spine. However, difficulties with interobserver discrepancy sometimes occurred while reading magnetic resonance myelography (MRM) because clear image definition was lacking. In this study, we tried to determine which pattern of CSF distribution is more reliable for diagnosis of CSF leakage by using MRM. METHODS: From January 2012 to August 2014, 19 SIH patients and 27 healthy controls (HC) were recruited into our study; 10 of the 19 patients were recovered (SIH-R) after treatment...

Spontaneous intracranial hypotension (SIH) is a more common than previously noted condition (1-2.5 per 50,000) typically caused by cerebrospinal fluid (CSF) leakage. Initial treatment involves conservative therapies, but the mainstay of treatment for patients who fail conservative management is the epidural blood patch (EBP). Subdural hematoma (SDH) is a common complication occurring with SIH, but its management remains controversial. In this report, we discuss a 62-year-old female who presented with a 5-week history of orthostatic headaches associated with nausea, emesis, and neck pain...

A 30-year-old woman at 28 weeks presented with sudden onset of intense headache, epigastric pain, hot flushes, nausea, vomiting, and stiff neck. Cerebral magnetic resonance imaging showed pathognonomic signs of spontaneous intracranial hypotension (SIH). Epidural blood patch was performed 2 times during pregnancy for symptoms relief in spite of medical treatments. No other recurrence was noted until the spontaneous delivery. SIH is a rare entity during pregnancy which may be diagnosed using magnetic resonance imaging...

INTRODUCTION: The syndrome of spontaneous intracranial hypotension has been increasingly diagnosed since its discovery through magnetic resonance imaging (MRI). It is a rare syndrome that is due to the leakage of cerebrospinal fluid (CSF) from a tear in the dura and can occur at any age, even among adolescents, but is most frequently seen among females in late middle age. CASE PRESENTATION: Here, we describe a 32-year-old woman with a two-month history of headaches and occasional nausea and vomiting (N/V)...

Spontaneous cerebrospinal fluid leak and intracranial hypotension associated with cervical spondylosis have rarely been observed, and only a few cases are reported. A 69-year-old woman, previously treated for rectal and thyroid cancer, complained of a non-postural persistent headache. The patient regularly practiced aerobic exercise, but a month earlier she had started experiencing headache and neck pain while exercising. Computed tomography(CT)showed bilateral chronic subdural hematomas, and magnetic resonance imaging(MRI)revealed diffuse dural enhancement and tonsillar herniation...

OBJECTIVE: The objective of our study was to determine whether the presence of individual imaging signs of spontaneous intracranial hypotension (SIH) is correlated with increasing duration of headache symptoms. Of particular interest is the relationship of symptom duration to dural enhancement because it is the most commonly identified imaging sign in patients with SIH. MATERIALS AND METHODS: Eighty-nine patients with SIH who underwent pretreatment brain MRI and total-spine CT myelography and whose medical record included data on the duration of clinical symptoms were included in this cross-sectional retrospective study...

We report 3 cases of spontaneous intracranial hypotension (SIH) associated with consciousness disorder and coma. In patients, SIH was suspected on a computed tomography scan and diagnosed by cerebral magnetic resonance imaging (MRI). Spinal MRI confirmed cerebrospinal fluid leakage. SIH should be seen as an underestimated cause of consciousness disorder and coma, especially in patients with a history of orthostatic headache, spinal injury, or oculomotor signs. Computed tomography scans should be examined for signs of SIH before operating on patients with a spontaneous subdural hematoma...

Cranial chronic subdural hematoma (CSH) occurs secondary to trauma or just spontaneously. In this clinical report, the authors presented a 39-year-old male patient who was admitted with cranial CSH. In further assessment of the patient, the authors found an underlying cerebrospinal fluid (CSF) leak at the level of cervical spine. Following evacuation of the CSH, it recurred. In the second session, the hematoma was re-evacuated and the CSF fistula repaired. The CSH did not recur again. In young adult patients with recurrent CSH and prior presence of bilateral CSH, a survey for an underlying spinal CSF leak should be considered in the differential, especially in the background of trauma...

Intracranial cerebrospinal fluid (CSF) hypotension usually arises in the context of known or suspected leak of CSF. This can be spontaneous, or due to central nervous system trauma or dural defects created during lumbar puncture or epidural anaesthesia. Spontaneous intracranial hypotension (SIH) is increasingly being recognised as a cause for orthostatic headache or spontaneous subdural haematoma where no other obvious cause is found. We review CSF physiology, the mechanism of symptom generation in CSF hypotension and the investigation and management of the syndrome...

: Intracranial pressure (ICP) is the pressure inside the bony calvarium and can be affected by a variety of processes, such as intracranial masses and edema, obstruction or leakage of cerebrospinal fluid, and obstruction of venous outflow. This review focuses on the imaging of 2 important but less well understood ICP disorders: idiopathic intracranial hypertension and spontaneous intracranial hypotension. Both of these ICP disorders have salient imaging findings that are important to recognize to help prevent their misdiagnosis from other common neurological disorders...

Spontaneous intracranial hypotension (SIH) caused by spontaneous spinal cerebrospinal fluid (CSF) leaks produces orthostatic headaches. Although upper arm pain or paresthesia is reportedly associated with SIH from spontaneous spinal CSF leak in the presence of orthostatic headache, low thoracic radicular pain due to spontaneous spinal CSF leak unassociated with postural headache is extremely rare. We report a 67-year-old female who presented with chronic, positional radicular right T11 pain. Computed tomography myelography showed a spontaneous lumbar spinal CSF leak at L2-3 and repeated lumbar epidural blood patches significantly alleviated chronic, positional, and lower thoracic radiculopathic pain...

OBJECTIVE: Spontaneous spinal CSF leaks cause spontaneous intracranial hypotension but no systematic study of the different types of these CSF leaks has been reported. Based on our experience with spontaneous intracranial hypotension, we propose a classification system of spontaneous spinal CSF leaks. METHODS: We reviewed the medical records, radiographic studies, operative notes, and any intraoperative photographs of a group of consecutive patients with spontaneous intracranial hypotension...

Intracraneal hypotension headache is a well known syndrome in neurosurgery practice. In most cases cerebrospinal fluid leaks are caused by medical interventions, such as lumbar puncture, peridural anesthesia and surgical interventions on the spine. Clinical symptoms tipically show orthostatic headache that resolves in supine position, and other symptoms like neck tightness, vertigo and diplopia. RMI diagnostic confirms paquimeningeal enhancement and subdural hygromas. Conservative treatment usually includes bed resting, hydratation and administration of caffeine or glucocorticoids, resolving spontaneously in one to four months...

BACKGROUND: The significance of sex- and age-related differences in the clinical course of spontaneous intracranial hypotension (SIH) was investigated. METHODS: We retrospectively studied 40 consecutive patients (female:male = 28:12, median age 41.5 years) treated under clinical diagnoses of SIH satisfying the International Classification of Headache Disorders 3rd edition criteria, including 37 patients (92.5%) with diffuse pachymeningeal enhancement. The patients were divided into two groups by age and sex, and the clinical and neuroimaging findings in each group were investigated...

BACKGROUND AND PURPOSE: Epidural blood patch treatment of spontaneous intracranial hypotension arising from ventral CSF leaks can be difficult secondary to challenges in achieving ventral spread of patching material. The purpose of this study was to determine the technical success rates and safety profile of direct needle placement into the ventral epidural space via a posterior transforaminal approach. MATERIALS AND METHODS: We retrospectively reviewed consecutive CT fluoroscopy-guided epidural blood patches from June 2013 through July 2015...

The authors report the case of a 28-year-old woman with a spontaneous cerebrospinal fluid leak from the sleeve of a redundant thoracic nerve root. She presented with postural headaches and orthostatic symptoms indicative of intracranial hypotension. CT myelography revealed that the lesion was located at the T-11 nerve root. After failure of conservative management, including blood patches and thrombin glue injections, the patient was successfully treated with surgical decompression and ligation of the duplicate nerve, resulting in full resolution of her orthostatic symptoms...
