OBJECTIVE: This study aimed to determine whether children's headache drawings can distinguish between pseudotumor cerebri and migraine. BACKGROUND: Headache features associated with pseudotumor cerebri (pseudotumor; idiopathic intracranial hypertension) are nonspecific and are difficult to distinguish clinically from migraines. Children's headache drawings have a high predictive value for migraine versus nonmigraine headaches. We hypothesized that drawings could help to differentiate pediatric headaches due to pseudotumor cerebri from those associated with migraines...

OBJECTIVE Idiopathic intracranial hypertension (IIH), or pseudotumor cerebri, is a complex and difficult-to-manage condition that can lead to permanent vision loss and refractory headaches if untreated. Traditional treatment options, such as unilateral ventriculoperitoneal (VP) or lumboperitoneal (LP) shunt placement, have high complication and failure rates and often require multiple revisions. The use of bilateral proximal catheters has been hypothesized as a method to improve shunt survival. The use of stereotactic technology has improved the accuracy of catheter placement and may improve treatment of IIH, with fewer complications and greater shunt patency time...

Bilateral papilledema secondary to obstructive or communicating hydrocephalus in patients with vestibular schwannomas is a known presentation; however, papilledema in the absence of hydrocephalus is rarely reported and its mechanism is poorly understood. We report a case of a 20-year-old woman presenting with visual deterioration and bilateral papilledema on fundoscopy. Magnetic resonance imaging (MRI) revealed a giant vestibular schwannoma with no sign of hydrocephalus. The only imaging evidence of increased pressure on preoperative imaging studies was seen on a T2-weighted MRI, where there was subtle dilatation of the arachnoid space of the optic sleeve...

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...

A 46-year-old man presented with severe visual loss and optic atrophy associated with optociliary shunt vessels. The diagnostic work-up revealed intracranial hypertension and cerebral venous sinus stenosis, with no evidence of previous thrombosis. In view of the severe visual dysfunction, both eyes were submitted to optic nerve sheath fenestration. After surgery, a regression of collateral vessels was observed in both eyes.

Because of a previous association of pseudotumor cerebri (PTC) with levonorgestrel, we wished to evaluate the use of levonorgestrel-eluting intrauterine devices ("levonorgestrel intrauterine systems", LNG-IUS) in our University of Utah and Rigshospitalet PTC patients. In our retrospective series, PTC prevalence was approximately 0.18% and 0.15% in the LNG-IUS population versus 0.02% and 0.04% in the non-LNG-IUS population (Utah and Rigshospitalet, respectively), with no significant differences in PTC signs and symptoms among the two groups...

BACKGROUND: Recent evidence suggests that olfaction is impaired in patients with pseudotumor cerebri (PTC). OBJECTIVES: To measure suprathreshold olfactory function by using the University of Pennsylvania Smell Identification Test (UPSIT), assessing its usefulness for routine clinical use. METHODS: Forty PTC patients underwent USPIT olfactory testing. RESULTS: Twenty-nine out of 40 (73%) PTC patients (36 women, 4 men; mean age 34 years) had reduced suprathreshold smell sensation according to UPSIT scores: 19 (47%) had mild microsmia, 9 (23%) had moderate microsmia, and one (3%) was classified as having severe microsmia...

Eighty percent of children with acute lymphoblastic leukemia (ALL) survive with current treatments. Neurotoxicity is an infrequent adverse event. We describe clinical presentations of neurological toxicity, phases of treatment when these adverse events were more frequent and patients ́ outcome. From January-1995 to December-2015, 1379 ALL cases were admitted. Neurotoxicity was diagnosed in 49 patients (3.6%) and classified according to neurological syndromes. Medical records, laboratory-tests and images were reviewed...

Familial Mediterranean fever (FMF) is characterized by recurrent episodes of fever accompanied by serosal, synovial, or cutaneous inflammation. The central nervous system (CNS) is rarely involved in FMF. The CNS involvement includes demyelinating lesions, posterior reversible encephalopathy syndrome, pseudotumor cerebri, optic neuritis, and cerebral vasculitis. Here, we present a 20-year-old man, a known case of FMF with abrupt left-sided hemiparesis. Brain magnetic resonance imaging revealed right periventricular infarction...

BACKGROUND: Cerebral edema peaks 36-72 h after moderate traumatic brain injury but thought to be uncommon after mild traumatic brain injury. Post-traumatic headache can develop 48-72 h post-injury, perhaps reflecting the developing cerebral edema. Pseudotumor cerebri can result from various causes, including cerebral edema, and is characterized by increased intracranial pressure, headache, visual, and other common symptoms. Our objective was to report a phenotypically identifiable post-traumatic headache subtype...

A ten-year-old boy presented to the hospital with body ache and joint pains for two months and headache, vomiting, and skin rash for three days. He was drowsy and lethargic at admission. Physical examination revealed bilateral papilledema. There were no cranial nerve involvement, neuromotor deficit, or signs of meningeal irritation. Computed tomography and magnetic resonance imaging of the brain did not reveal any evidence of cerebral edema or space occupying lesion. In view of the high endemicity of brucellosis in the area, Brucella agglutination test (BAT) was done at the time of admission and was negative...

Type 1 narcolepsy (NT1) is a chronic primary disorder of hypersomnolence characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, hypnagogic hallucinations and disrupted nocturnal sleep. NT1 is linked to hypothalamic hypocretin deficiency, strongly associated with Human Leukocyte Antigen (HLA) marker DQB1*06:02 and of probable autoimmune origin. NT1 is usually associated with increased rates of overweight and obesity, and sometimes with increases in overnight blood pressure and increased rates of hypoventilation with raised CO2 levels overnight...

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...

In this article, we present the case of a 12-year-old female child who complained of bilateral temporal and frontal headache for 2 to 3 months with nausea and vomiting. Physical examination revealed right-sided sixth cranial nerve palsy and papilledema in ophthalmoscopy. To find the cause of increased intracranial pressure, the patient underwent brain imaging and brain MRI showed no abnormality. Ultimately, lumbar puncture (LP) was performed and cerebrospinal fluid (CSF) pressure was 280 mmH2O with normal chemistry...

BACKGROUND: The modified Dandy criteria and the newer diagnostic criteria for pseudotumor cerebri syndrome (PTCS) are both used to diagnose intracranial hypertension (IH). In comparison to the modified Dandy criteria, the PTCS criteria stratify the IH diagnosis into definite, probable, and suggested categories, exclude clinical symptoms, and use radiologic evidence for diagnosis. There is a lack of consensus on which criteria should be used in the pediatric population. The purpose of this study was to compare the diagnostic criteria for PTCS to the modified Dandy criteria and to identify limitations within both sets of criteria...

Idiopathic intracranial hypertension (IIH), formerly known as pseudotumor cerebri, is a disease of elevated intracranial pressure that is thought to develop due to impaired CSF absorption related to elevated venous sinus pressure in the setting of increased intraabdominal and thoracic pressures. Symptoms can be disabling and, if left untreated, can lead to permanent visual loss. Previous treatments directed toward vision preservation include CSF diversion through shunting and optic nerve sheath fenestration...
