OBJECTIVE: The objective of this study was to identify a relationship between cerebrospinal fluid (CSF) volume removal and change in CSF pressure in children with suspected idiopathic intracranial hypertension (IIH). METHODS: We performed a cross-sectional study of children 22 years and younger who underwent a lumbar puncture (LP) and had a documented opening pressure, closing pressure, and volume removed. Relationship between volume removal and pressure change was determined using a fractional polynomial regression procedure...

Idiopathic intracranial hypertension (IIH) is characterised by increased intracranial pressure with normal cerebrospinal fluid, and no evidence of space occupying process, meningeal pathology or venous thrombosis. The condition is associated with obesity, especially in women of childbearing age. IIH is a rare but serious cause of headache, and constitutes a differential diagnosis for sudden-onset headache, particularly if the patient has visual disturbances not related to migraine and reports pulsatile tinnitus, cranial nerve palsy or radiculopathy...

This report is of two cases of asymmetrical papilloedema in patients with asymmetrical intraocular pressures (IOPs). The first patient presented with headaches, transient visual obscurations (TVOs), and elevated IOPs, and was found to have increased intracranial pressure caused by a torcula meningioma. He developed papilloedema after his IOPs were pharmacologically lowered; the papilloedema resolved after the IOP became elevated again after stopping his glaucoma drops, and then again returned as the IOP reduced when the drops were restarted...

Peter Gates, Peter McNeill
This paper reports 14 patients with idiopathic intracranial hypertension (IIH) who experienced immediate and sustained resolution of their IIH; 13 in the setting of a low-pressure headache and 1 who underwent lumbar drainage for 4 days draining the cerebrospinal fluid (CSF) at a rate of 5-15 mL/h. These observations, if confirmed, suggest that draining CSF using a temporary lumbar drain draining CSF at a rate greater than it is produced may potentially have a pivotal role in the management of IIH.

This is a 25-year observational retrospective review of 372 consecutive participants with optic disc drusen or resolved papilloedema from idiopathic intracranial hypertension. The prevalence of optic disc drusen at 19% among eyes with resolved papilloedema was approximately 10 times higher and significantly increased (p < 0.001) as compared with the occurrence in the general population. Eyes with both resolved papilloedema and optic disc drusen had similar visual acuity and visual field outcome as compared with resolved papilloedema alone...

Papilloedema is a key clinical finding in the diagnosis of idiopathic intracranial hypertension (IIH). However, newly proposed criteria allow diagnosis without papilloedema only if certain neuroimaging features are present. It is currently unclear if these findings persist upon resolution of papilloedema and IIH. A retrospective chart review identified three groups of patients (six per group) who had received orbital imaging within 4 weeks of fundoscopic examination: (1) IIH patients without active papilloedema, (2) IIH patients with active papilloedema, and (3) patients with no history of IIH or papilloedema...

The purpose of this study was to report the incidence and describe the characteristics of sixth cranial nerve (CN VI) palsy in paediatric patients with intracranial hypertension (IH). A retrospective chart review of central Ohio children diagnosed with IH over the 3-year period from 2010 to 2013 was conducted. IH without identifiable cause was defined as idiopathic intracranial hypertension (IIH), whereas IH with identifiable pathologic aetiology was deemed secondary intracranial hypertension (SIH). A subset of patients with CN VI palsy was identified...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic hereditary kidney disease characterized by progressive enlargement of renal cysts. The incidence is 1-2‰ worldwide. Mutations in two genes (PKD1 and PKD2) cause ADPKD. Currently, there is no pharmaceutical treatment available for ADPKD patients in China. Summary: This review focused on advances in clinical manifestation, gene diagnosis, risk factors, and management of ADPKD in China. There is an age-dependent increase in total kidney volume (TKV) and decrease in renal function in Chinese ADPKD patients...

Coarctation of the aorta (CoA) is reported to be associated with an increased risk for migraine. We describe here the case of a 13-year-old female patient who presented migraine with aura after surgical repair of CoA with a stent. As possible reasons for her condition, we postulate host responses to stent placement and/or disturbed cerebral autoregulation related to intracranial hypertension before the surgical repair and hypotension afterward, leading to hypoperfusion. This case demonstrates that de novo migraine with aura can occur after surgical repair of CoA and should be recognized as a potential complication...

Bethanie Morgan-Followell, Shawn C Aylward
The authors aimed to compare the opening pressures of children with demyelinating disease to children with primary intracranial hypertension. Medical records were reviewed for a primary diagnosis of demyelinating disease, or primary intracranial hypertension. Diagnosis of demyelinating disease was made according to either the 2007 or 2012 International Pediatric Multiple Sclerosis Study Group criteria. Primary intracranial hypertension diagnosis was confirmed by presence of elevated opening pressure, normal cerebrospinal fluid composition and neuroimaging...

BACKGROUND: Meningioma is a frequent primary intracranial tumor, the etiology of which is potentially related to adiposity. Metabolic syndrome (MetS) is an increasingly common disease characterized by having at least three of the following conditions: central adiposity, arterial hypertension, dyslipidemia, and insulin resistance. Only one prior study investigated MetS in relation to meningioma risk and found a positive association between the two. RESULTS: Among 2,027 cases and 20,269 controls, body mass index was positively associated with meningioma (p-value for trend < 0...

The pseudotumor cerebri syndrome (PTCS), also known as idiopathic intracranial hypertension (IIH), is characterized by signs and symptoms of increased intracranial pressure such as headache and cranial nerve palsies, in the absence of any space-occupying mass. This condition commonly affects overweight women of childbearing age, even if it is also frequent in men and children. Children with PTCS may present with atypical signs and symptoms, with a different prognosis compared to adults. However, the treatment is the same for both children and adults, even if there are no strict treatment guidelines in regards...

OBJECTIVE: Closed head injury rarely predisposes patients, particularly children, to the development of dural sinus thrombosis. In addition, most cases of sinus thrombosis are subacute in nature. The following is a case report of a precipitous course of dural sinus thrombosis after closed head injury in a pediatric trauma patient. DESCRIPTION: A 14-year-old African American girl presented to the emergency department as a trauma activation. She was an unrestrained rear-seat passenger involved in a motor vehicle collision during which she was ejected...

Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril...
