intracranial hypertension syndrome

Kathryn F Kirchoff-Torres, Ekaterina Bakradze
PURPOSE OF REVIEW: Cerebral hyperperfusion syndrome (CHS) is a rare but significant complication after carotid revascularization and is increasingly recognized after acute stroke treatments. In this review, we discuss the epidemiology and pathophysiology of CHS, clinical presentation including ipsilateral headache, seizures, and focal neurological deficits, and radiographic presentation. We propose preventive therapies with emphasis on acute stroke post-thrombectomy hyperperfusion. RECENT FINDINGS: CHS was first described after carotid revascularization but is now also reported in patients with acute ischemic stroke...

BACKGROUND AND PURPOSE: Idiopathic intracranial hypertension is a syndrome of raised intracranial pressure of unknown etiology. Few MR imaging-based studies have investigated arterial and venous blood flow in these patients. Results are inconclusive, and to our knowledge, no comparison of the hemodynamic parameters before and after CSF pressure reduction has been published. The aim of this study was to assess the short-term effects of normalizing CSF pressure on intracranial flow to better understand the pathophysiology of idiopathic intracranial hypertension...

BACKGROUND: Garcin syndrome, which consists of unilateral palsies of almost all cranial nerves without either sensory or motor long-tract disturbances or intracranial hypertension, can be caused by malignant tumors at the skull base. The case of a patient with lung cancer that metastasized to the sphenoid bone and resulted in Garcin syndrome is presented. CASE PRESENTATION: A 76-year-old woman was diagnosed as having non-small cell lung cancer with pericardial and diaphragmatic infiltration, cT4N1M0, stage 3A...

Headache is an uncommon symptom in Guillain-Barré syndrome (GBS). We review four clinical settings related to GBS in which headache may be present. We focus on pathophysiological explanations, alerting the clinician to further potential investigations and treatment. Most reports of headache in GBS occur in the context of the posterior reversible encephalopathy syndrome, an increasingly recognized dysautonomia-related GBS complication. Less frequent is headache in the setting of increased intracranial pressure and papilledema (secondary intracranial hypertension), Miller Fisher syndrome, and cerebral venous sinus thrombosis...

Roseola infantum is a clinical syndrome characterized by high fever followed by the emergence of a rash. Case reports have documented an association between bulging fontanelles and roseola. We propose a novel mechanism for the development of intracranial hypertension caused by human herpesvirus 6-induced cytokine elevation leading to increased cerebrospinal fluid production.

Crouzon syndrome (CS) is one of the craniosynostosis syndromes that leads to early fusion of cranial sutures and increased intracranial pressure. Intracranial hypertension is a serious complication that may lead to vision loss and cognitive impairment. Early detection and management are necessary to prevent complications. The authors present a patient with CS who underwent posterior cranial vault reconstruction with internal distraction after multiple episodes of headache and papilledema. The patient was unaware of any loss of color vision before the surgery; however, he noted an improvement in his color vision after the surgery...

BACKGROUND: The recommended treatment for craniosynostosis, is cranial vault expansion to prevent increased intracranial pressure and optimize developmental outcomes. Some patients complain about postoperative headaches and occasionally require revision to treat increased intracranial pressure. This study examines whether specific factors are associated with an increased risk of postoperative headaches or intracranial hypertension. METHODS: This retrospective cohort included patients with craniosynostosis from 1995 and 2010...

Elevated intracranial pressure (ICP) can result in multiple neurologic sequelae including vision loss. Inducible models of ICP elevation are lacking in model organisms, which limits our understanding of the mechanism by which increased ICP impacts the visual system. We adapted a mouse model for the sustained elevation of ICP and tested the hypothesis that elevated ICP impacts the optic nerve and retinal ganglion cells (RGCs). ICP was elevated and maintained for 2 weeks, and resulted in multiple anatomic changes that are consistent with human disease including papilledema, loss of physiologic cupping, and engorgement of the optic nerve head...

Idiopathic intracranial hypertension (IIH) is a syndrome of elevated intracranial pressure without evidence of intracranial mass lesion or venous thrombosis, and bland cerebrospinal fluid examination. It mostly affects overweight women of childbearing age and if left untreated, can lead to permanent visual loss. Visual decline in this condition is generally slow, over months to years. However, a small proportion of patients develop rapidly progressive visual loss within days or weeks of onset of headaches. We describe a 29 year-old patient with fulminant IIH in whom inadequate fundoscopy and assessment of vision contributed to a delay in diagnosis and poor outcome...

RATIONALE: Venous sinus thrombosis is a special type of cerebrovascular disease. Its incidence is low and its symptoms are lack of specificity. And its early diagnosis and treatment are very difficult. PATIENT CONCERNS: This paper reported a rare case of a 43-year-old female who presented with cerebral venous thrombosis (CVT) complicated with cerebral artery infarction and secondary epileptic seizures due to oral contraceptives. DIAGNOSES: The final diagnosis was intracranial venous sinus thrombosis, acute cerebral infarction in the left parietal lobe, intracranial hypertension syndrome, and continuous epilepsy...

The visual impairment and intracranial pressure (VIIP) syndrome is a neuro-ophthalmologic condition described in astronauts returning from long duration space missions. Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is characterized by a chronic elevation of intracranial pressure (ICP) in the absence of an intracranial mass lesion. Because VIIP and IIH share some neurologic and ophthalmologic manifestations, the latter might be used as a model to study some of the processes underlying VIIP...

Fibromyalgia (FM) is a debilitating, widespread pain disorder that is assumed to originate from inappropriate pain processing in the central nervous system. Psychological and behavioral factors are both believed to underlie the pathogenesis and complicate the treatment. This hypothesis, however, has not yet been sufficiently supported by scientific evidence and accumulating evidence supports a peripheral neurological origin of the symptoms. We postulate that FM and several unexplained widespread pain syndromes are caused by chronic postural idiopathic cerebrospinal hypertension...

Papilledema in a patient with human immunodeficiency virus (HIV)/acquired immune deficiency syndrome is an alarming finding. Any condition giving rise to raised intracranial tension (ICT) can cause papilledema, and in these patients, it could be secondary to opportunistic infections like meningitis to neoplasm. We report a case of a 28-year old female with HIV on antiretroviral therapy, who presented to us, with papilledema. Her fundus examination revealed superficial hemorrhages and Roth's spots along with papilledema...

BACKGROUND: Transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL) is benign and self-limited, with neurologic deficits including sensory disturbance of one body side, aphasia, nausea/vomiting, weakness, decreased vision, homonymous hemianopsia, photophobia. Acute confusional state can rarely occur. Papilledema and intracranial hypertension have also been described. It is a rare entity mainly affecting adults; however, it has been sporadically described in children and adolescents...

PREMISE: Idiopathic intracranial hypertension (IIH), previously known as pseudotumor cerebri syndrome (PTC) is a serious neurological disorder that can lead to irreversible visual loss. Predominantly a disorder affecting women in reproductive years, the pediatric population is not spared. PROBLEM: In the past few years, the condition has been redefined, due to new accepted values for opening pressure in children and advances in neuroimaging. Emerging techniques in ophthalmology are being increasingly used to monitor disease in these patients...

Visual impairment intracranial pressure (VIIP) syndrome is considered an unexplained major risk for future long-duration spaceflight. NASA recently redefined this syndrome as Spaceflight-Associated Neuro-ocular Syndrome (SANS). Evidence thus reviewed supports that chronic, mildly elevated intracranial pressure (ICP) in space (as opposed to more variable ICP with posture and activity on Earth) is largely accounted for by loss of hydrostatic pressures and altered hemodynamics in the intracranial circulation and the cerebrospinal fluid system...

Epidermoid cyst (EC) or cholesteatoma is a benign tumor, often of congenital origin, occurring in the sub-arachnoidian spaces. Its treatment is based on surgery. We report the case of a 38 year-old patient presenting with progressive intracranial hypertension syndrome associated with anterior pituitary insufficiency signs of the corticotropic, thyrotropic, gonadotropic axis occurring 1 year before. Brain MRI showed a craniopharyngioma. Anatomopathologic evaluation of the specimen showed epidermoid cyst.
