Spontaneous intracranial hypotension (SIH) is a syndrome in which hypovolemia of the cerebrospinal fluid (CSF) results in various symptoms. Although its prognosis is usually benign, cases with a rapid neurologic deterioration resulting in an altered mental status have been reported. One of the characteristic radiographic findings in such cases is the presence of bilateral accumulation of subdural fluid (hematoma/hygroma). When SIH-related subdural hematoma is present only unilaterally with a concomitant midline shift, making an accurate diagnosis may be challenging, and inadvertent hematoma evacuation may result in further neurologic deterioration. We report a 58-year-old woman with an altered mental status who had visited a local hospital and in whom a brain CT showed a unilateral subdural hematoma with a marked midline shift. She was referred to our department because of her neurologic deterioration after hematoma evacuation. A CT myelography revealed a massive CSF leakage in the entire thoracic epidural space. She made a full neurologic recovery following blood patch therapy. Our case is unique and educational because the suspicion for SIH as an underlying cause of subdural hematoma is warranted in nongeriatric patients not only with bilateral but also unilateral lesions. An immediate search for CSF leakage may be important in cases with failed hematoma evacuation surgery.

The most common cause of spontaneous intracranial hypotension headache is a cerebrospinal fluid (CSF) leakage, but the underlying mechanisms remain unknown. Intracranial hypotension is characterised by diffuse pachymeningeal enhancement on cranial MRI features, low CSF pressure and orthostatic headaches mostly caused by the dural puncture. We report a 31-year-old woman who presented to our services with reports of continuous severe bifrontal headache, which increased on sitting up and resolved on lying down. MRI of the cervical and lumbosacral spine showed signs of CSF leak; hence, patient was diagnosed with spontaneous intracranial hypotension headache. A CT-guided epidural blood patch was done at L4–5 with fibrin glue injected at the site of leak. The patient’s signs and symptoms improved after the procedure.

Object Spontaneous intracranial hypotension (SIH) is a potentially serious pathological syndrome consisting of specific symptoms and neuroradiological signs that can sometimes be used to assess the efficacy of the treatment. In this paper the authors report a series of 28 patients with this syndrome who were all treated with an epidural blood patch at the authors' institution. The authors propose a novel physiopathological theory of SIH based on some anatomical considerations about the spinal venous drainage system. Methods Between January 1993 and January 2007, the authors treated 28 patients in whom SIH had been diagnosed. Twenty-seven of the 28 patients presented with the typical findings of SIH on brain MR imaging (dural enhancement and thickening subdural collections, caudal displacement of cerebellar tonsils, and reduction in height of suprachiasmatic cisterns). The sites of the patients' neuroradiologically suspected CSF leakage were different, but the blood patch procedure was performed at the lumbar level in all patients. The patients were then assessed at 3-month and 1- and 3-year follow-up visits. At the last visit (although only available for 11 patients) 83.3% of patients were completely free from clinical symptoms and 8.3% complained of sporadic orthostatic headache. Results The authors think that in the so-called SIH syndrome, the dural leak, even in those cases in which it can be clearly identified on neuroradiological examinations, is not the cause of the disease but the effect of the epidural hypotension maintained by the inferior cava vein outflow to the heart. The goal of their blood patch procedure (a sort of epidural block obtained using autologous blood and fibrin glue at the L1–2 level) is not to seal CSF leaks, but instead to help in reversing the CSF-blood gradient within the epidural space along the entire cord. Conclusions The authors' procedure seems to lead to good and long-lasting clinical results.

Abstract Background Spontaneous intracranial hypotension (SIH) is characterized by positional headache caused by low CSF pressure, without any major traumatic event. Optimal treatment is still debated; epidural blood patch (EBP) is usually used after unsuccessful conservative treatment with variable efficacy and potentially severe complications. Although steroids have been reported to be beneficial, their effectiveness is still controversial, and more clinical evidence is needed. Case presentation A 37-year-old woman was admitted to the neurology department due to severe orthostatic headache with nausea over the last 5 days. No trauma history or spinal manipulation were mentioned. On arrival, neurological examination, brain CT, and laboratory investigation were normal. Intracranial hypotension was clinically suspected, and lumbar puncture revealed low opening pressure. Brain MRI demonstrated pachymeningeal gadolinium enhancement and distended and rounded dural venous sinuses, while cervicothoracic spine MRI revealed thoracic CSF leakage, leading to SIH diagnosis. The patient was treated with high-dose intravenous methylprednisolone, with complete clinical resolution within 24 h. Conclusions Our case, combined with literature evidence, supports the high-dose intravenous corticosteroids as a reasonable treatment option in selected cases, before trying EBP or surgical repair. Randomized clinical trials are needed, in order to optimize SIH patients’ outcomes.

Abstract Purpose of Review Spontaneous intracranial hypotension (SIH) is recognized far more commonly than before, and it is well known that SIH is sometimes complicated by chronic subdural hematoma (SDH). We reported a patient who was treated with epidural blood patch (EBP) five times for refractory SIH and SDH surgery. Recent Findings We experienced that targeted EBP was useful in refractory SIH, and also can be performed safely prior to drainage of the hematoma. Summary We report the case of SIH patient with a bilateral SDH who came to our hospital and was discharged 2 weeks later with no neurologic deficit after trephination and five times EBP treatment. It shows that targeted EBP was useful in refractory SIH, and also can be performed safely prior to drainage of the hematoma.

Objective An epidural blood patch (EBP) is the mainstay of treatment for refractory spontaneous intracranial hypotension (SIH). We evaluated the treatment efficacy of targeted EBP in refractory SIH. Methods All patients underwent brain magnetic resonance imaging (MRI) with contrast and heavily T2-weighted spine MRI. Whole spine computed tomography (CT) myelography with non-ionic contrast was performed in 46 patients, and whole spine MR myelography with intrathecal gadolinium was performed in 119 patients. Targeted EBPs were placed in the prone position one or two vertebral levels below the cerebrospinal fluid (CSF) leaks. Repeat EBPs were offered at 1-week intervals to patients with persistent symptoms, continued CSF leakage, or with multiple leakage sites. Results Brain MRIs showed pachymeningeal enhancement in 127 patients and subdural hematomas in 32 patients. One hundred fifty-two patients had CSF leakages on heavily T2-weighted spine MRIs. CSF leaks were also detected on CT and MR myelography in 43 and 111 patients, respectively. Good recovery was achieved in all patients after targeted EBP. No serious complications occurred in patients treated with targeted EBP during the 1 to 7 years of follow-up. Conclusions Targeted and repeat EBPs are rational choices for treatment of refractory SIH caused by CSF leakage.

Introduction: Spontaneous intracranial hypotension (SIH) is a rare syndrome, still underdiagnosed. It manifests with orthostatic headache and improves with decubitus, and may present nausea, vomiting, diplopia, vestibular and auditory symptoms. The main cause of SIH is spontaneous CSF leaks usually in the cervicothoracic transition. Case report: RSA, male, 36 years, he presented holocranial headache triggered in the orthostatic position and decubitus improvement associated with nausea. He denied visual complaints, fever, trauma or invasive procedures. Neurological examination: discrete neck stiffness, fundoscopy and others exams without abnormalities. Brain and cervical spine MRI, also venous AngioMRI were normal. Dorsal spine MRI with extradural collection. Arterial AngioMRI with 2,50x2,0mm aneurysmatic dilation in the right supraclinoid internal carotid artery. Opening pressure of CSF 6cmH2 O. Analgesia, decubitus rest and parsimonious hydration were performed. In cisternoscintigraphy, CSF leakage into the extradural space at the level of D3/D4 and D4/D5 on the left, delay in the rise of the tracer for brain convexities in 24 hours images, suggestive of CSF hypotension. Blood patch guided by radioscopy was performed, with improvement after 2 weeks of the 3rd procedure. Conclusion: Knowing the types of headache and its etiologies is essential to orientate diagnosis and treatment, avoiding unnecessary exams. In this case report, the microaneurysm found did not justify the complaint of orthostatic headache. The rapid diagnosis of spontaneous CSF leaks provided early treatment avoiding complications such as subdural hematomas, cerebral venous thrombosis, pituitary dysfunction.
