Spontaneous or primary and secondary but presenting the same findings on brain magnetic resonance imaging. Intracranial hypotension IH is a treatable cause of persistent headaches. Brain and occasionally spinal MRI studies with gadolinium enhancement should be undertaken. By very definition the opening CSF pressure is low below 60 mm H2O and often a dry tap is encountered. A patient with symptoms of low intracranial pressure including postural headache and hyperacusis. Magnetic resonance imaging MRI has allowed us to establish a set of radiologic signs associated with intracranial hypotension syndrome.

Spontaneous or primary and secondary but presenting the same findings on brain magnetic resonance imaging. Specific headache types such as low pressure headache positional or cough headache with possible CSF flow obstruction Chiari malformation or colloid cyst meningitic features vasculitic features or cranial nerve neuropathies require specialist MRI protocols and should ideally be reviewed by a Neuroradiologist. Typical imaging findings consist of subdural fluid collections pachymeningeal enhancement pituitary hyperaemia and brain sagging but magnetic resonance imaging may be normal. The MRI findings represent the sum of loss of CSF volume and compensatory changes in response to the leakage. ALL patients with suspected intracranial hypotension should have cranial brain MRI with contrast to look for these findings and for. By very definition the opening CSF pressure is low below 60 mm H2O and often a dry tap is encountered.

Low pressure headaches are caused by low cerebral spinal fluid CSF pressure or volume and they may be spontaneous or provoked for example after lumbar puncture inadvertent dural puncture. We present three patients who complained of postural headache related to different types of intracranial hypotension. Intracranial hypotension syndrome is characterized by a decrease in cerebrospinal fluid CSF pressure to less than 60 mm H2O associated with occipital headache radiating to the frontal and temporal zones. Findings are partly influenced by cerebral displacement. Low pressure headaches are caused by low cerebral spinal fluid CSF pressure or volume and they may be spontaneous or provoked for example after lumbar puncture inadvertent dural puncture.

33 Patients with any headache disorder had a higher rate of any intracranial abnormality as compared with the nonheadache population 29 vs 22 including major 11 vs 10 and minor 17 vs 13 categories. 1 An MRI with gadolinium injection and an MR angiogram were performed showing mild enhancement of the meningeal structures especially on coronal T2 views Figures 1 and 2. Low pressure headaches are caused by low cerebral spinal fluid CSF pressure or volume and they may be spontaneous or provoked for example after lumbar puncture inadvertent dural puncture during spinal anaesthesia or neurosurgical procedures.

Intracranial hypotension syndrome is characterized by a decrease in cerebrospinal fluid CSF pressure to less than 60 mm H2O associated with occipital headache radiating to the frontal and temporal zones. Brain MRI with injected contrast dye may reveal enhancement of the meninges lining of the brain and sometimes indicate evidence of the brain sagging downward from the skull toward the neck. Thin bilateral subdural fluid accumulation over the cerebral and cerebellar convexities is commonly seen in about 50 of patients. The condition may be frustrating to diagnose even when the cause is strongly suspected particularly in the less dramatic cases. 33 Patients with any headache disorder had a higher rate of any intracranial abnormality as compared with the nonheadache population 29 vs 22 including major 11 vs 10 and minor 17 vs 13 categories.

Lumbar puncture and CSF analysis are done if headache is progressive and findings suggest idiopathic intracranial hypertension eg transient obscuration of vision diplopia pulsatile intracranial tinnitus or chronic meningitis eg persistent low-grade fever cranial neuropathies cognitive impairment lethargy vomiting. Brain and occasionally spinal MRI studies with gadolinium enhancement should be undertaken. Low pressure headaches are caused by low cerebral spinal fluid CSF pressure or volume and they may be spontaneous or provoked for example after lumbar puncture inadvertent dural puncture during spinal anaesthesia or neurosurgical procedures. They typically do not cause mass effect and represent small hygromas. A A coronal and B axial T1 MRI with gadolinium demonstrating diffuse pachymeningeal.
