PURPOSE Spontaneous intracranial hypotension (SIH) is a rare type of headache. The association of SIH with malignancy and disseminated intravascular coagulation (DIC) has not previously been reported. CASE REPORT A 60-year-old woman had orthostatic headache for more than one month before admission. MRI of brain showed diffuse pachymeningeal enhancement with bilateral subdural hematoma. MR mye...

The association of spontaneous intracranial hypotension with cerebral venous sinus thrombosis is rare. We report here a case of extensive cerebral venous sinus thrombosis involving three sinuses following spontaneous intracranial hypotension. The patient presented no other thrombotic risk factors except for spontaneous intracranial hypotension. This case adds to the evidence that spontaneous in...

The stress-induced hyperthermia (SIH) response is the transient change in body temperature in response to acute stress. This body temperature response is part of the autonomic stress response which also results in tachycardia and an increased blood pressure. So far, a SIH response has been found in a variety of species (including rodents, baboons, turtles, pigs, impalas and chimpanzees), and th...

A literature search found no clinical trials or guidelines addressing the management of spontaneous intracranial hypotension (SIH). Based on the available literature and expert opinion, we have developed recommendations for the diagnosis and management of SIH. For typical cases, we recommend brain magnetic resonance (MR) imaging with gadolinium to confirm the diagnosis, and conservative measure...

Spontaneous intracranial hypotension (SIH) is an important cause of new daily persistent headache. It is thought to be due to spontaneous spinal cerebrospinal fluid (CSF) leaks, which probably have a multifactorial etiology. The classic manifestation of SIH is an orthostatic headache, but other neurological symptoms may be present. An epidural blood patch is thought to be the most effective tre...

The subdural hematoma (SDH) could be a serious complication of the spontaneous intracranial hypotension (SIH) that is a rare but well-known entity. We reported four illustrative cases of subdural hematomas revealing SIH. Three women and a man with mean age of 58.5 years. In three cases we noted sudden headaches, progressive and postural in one. CT scan has diagnosed the subdural hematomas that ...

Spontaneous intracranial hypotension (SIH) is characterized by orthostatic headache. Typical abnormal magnetic resonance imaging (MRI) findings have been considered to be the sine qua non of SIH, but a sizeable minority of patients has normal results using conventional MRI. The purpose of this study was to evaluate the difference in cerebrospinal fluid (CSF) flow dynamics between patients and h...

This is a case study of a 34-year-old woman who was admitted to hospital with a history of severe orthostatic headache. She was diagnosed as having spontaneous intracranial hypotension (SIH) by undetectable cerebrospinal fluid (CSF) pressure at lumbar puncture, and with evidence of diffuse dural enhancement of the brain detected by magnetic resonance imaging (MRI). However, the contrast-enhance...

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 propo...

Cerebral venous thrombosis (CVT) has been reported as an uncommon complication of spontaneous intracranial hypotension (SIH). Since this is a rare presentation, we report a patient with SIH complicated by CVT and intracerebral hemorrhage (ICH). A 43-year-old woman presented with a 2-day history of orthostatic headache and neck stiffness. Magnetic resonance imaging (MRI) of the brain demonstrate...
