“…The same finding was reported by Silbergleit et al [154] in 6 patients with PTS using a 0.35 Tesla magnet. Benefiting from improved technology, Moser et al [120] used a heavily-weighted T2 MR technique (1.5 Tesla) to investigate the brain water content in 10 patients with PTS. They found an increase in the signal white matter free water content as reflected in prolongation of the T2 relaxation time.…”

“…Most MRI studies of papilledema focus on pseudotumor cerebri in adults [3,4,5,6,7,8,9,10,11,12]. This case demonstrates that some of the MRI findings in a pediatric tumor patient with increased ICP are similar to pseudotumor cerebri findings [5].…”

“…Diagnosis involves direct fundoscopic examination, while further neuroimaging tests are performed to exclude tumors, hematomas and venous sinus thrombosis [2,3]. The majority of magnetic resonance imaging (MRI) papilledema studies have been focused on pseudotumor cerebri in predominantly the adult population [3,4,5,6,7,8,9,10,11,12]. In the pediatric population, MRI detection of papilledema caused by intracranial tumor and increased ICP has not been described specifically.…”

We present a case report of a 21-month-old female patient to highlight magnetic resonance (MR) imaging findings associated with papilledema in a pediatric patient with an intracranial tumor. The MR findings included optic disc elevation, dilated perioptic subarachnoid spaces, optic nerve tortuosity and restricted diffusion in the optic nerve heads, all of which resolved upon resolution of raised intracranial pressure (ICP) and papilledema. The case demonstrates that both conventional and diffusion-weighted MR imaging findings can detect the presence, and follow posttreatment resolution, of increased ICP and papilledema in a pediatric tumor patient. The postoperative resolution of optic disc elevation clearly indicates the intracranial tumor etiology.

“…Says and Joynt reported microscopic evidence of intracellular and extracellular edema [29] and later some MR studies also showed increased water content of the brain [30] and water diffusion in subcortical white matter [31] providing an indirect evidence of brain edema without further confirmation. Dandy first hypothesized that the volume of either cerebral blood or CSF might be increased in this condition.…”

İdiyopatik intrakraniyal hipertansiyonun -diğer adıyla psödotümör serebrininpatofizyolojisi üzerine bir güncelleme SummaryIdiopathic intracranial hypertension (IIH) is a syndrome characterized by increased intracranial pressure of unknown cause, leading to severe headache, papilledema and visual disturbances. Its former name, pseudotumor cerebri, has gained popularity recently. The strongest and most consistent risk factors of IIH are obesity and female gender. Infrequently, IIH may present in the absence of papilledema showing a headache profile similar to chronic daily headache with migrainous features. There have been several proposed mechanisms to explain the etiology of this disorder associated with various clinical conditions. In recent years, some inflammatory factors, natriuretic peptides and aquaporins have been proposed as possible contributors of the pathogenesis. On the other hand, some investigators have reported that bilateral transverse sinus stenosis is seen in the majority of IIH patients; therefore, dural sinus stent placement is used in some patients. No single theory has been able to provide a comprehensive answer, and there is no consensus about the exact cause of IIH. The aim of this review was to discuss the new insights on the mysterious pathogenesis of IIH.
