Context: The persisting embryonal infundibular recess (PEIR) is a rare anomaly of the floor of the third ventricle with a debated pathogenesis. It can be a cause of misdiagnosis in case of cystic lesions of the sellar and suprasellar area. Objective: To describe two recently evaluated cases and provide a systematic literature review. Evidence acquisition and Case Descriptions: PEIR has been previously reported in 6 adult patients. As in some cases it was associated to hydrocephalus and/or empty sella, a possible role of altered intracranial pressure in PEIR formation has been postulated...

BACKGROUND: Intracranial hypertension is believed to contribute to secondary brain insult in traumatically brain injured patients. Currently the diagnosis of intracranial hypertension requires intracranial monitoring or advanced imaging. Unfortunately, prehospital transport times can be prolonged, delaying time to the initial radiographic assessment. The aim of this study was to identify clinical variables associated with raised intracranial pressure (ICP) prior to the completion of neuroimaging...

Objective: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment. Among patients who primarily underwent craniotomy for the removal of hematoma, some consequently developed aggressive intracranial hypertension and brain edema, and required secondary decompressive craniectomy (DC). To avoid reoperation, we investigated factors which predict the requirement of DC by comparing groups of ASDH patients who did and did not require DC after craniotomy. Methods: The 129 patients with ASDH who underwent craniotomy from September 2007 to September 2017 were reviewed...

In their comments, Drs. De Bernardo and Rosa stated that our paper was missing several references
 related to optic nerve sheath diameter ONSD assessments. Specifically, they state that we neglected to
 mention that ultrasound has been used since the 1970s, that we did not emphasize the role of
 Standardized A scans, and they reference some of their publications in which they emphasize the
 importance of these scans in diagnosing optic nerve lesions and benign intracranial hypertension...

PURPOSE: In mechanical thrombectomy (MT) for ischemic stroke, endothelial cells (ECs) from intracranial blood vessels adhere to the stent retriever device and can be harvested. However, understanding the molecular biology and the role of the endothelium in different pathological conditions remains insufficient. The purpose of the study was to characterize and analyze the molecular aspect of harvested ECs using cell culture and transcriptomic techniques in an MT swine model relevant to clinical ischemic stroke...

Background: Idiopathic intracranial hypertension (IIH) is primarily a disorder of young obese women of unknown etiology. The clinical presentation of IIH is similar to that of sinus thrombosis. The incidence of transverse sinus stenosis (TSS) reaches up to 90% of patients with IIH compared with normal subjects, and venous sinus thrombosis was reported in 11.4% of patients previously diagnosed as having IIH. Patients with thrombosis showed an abnormal region of double- track pattern on gadolinium (Gd) - enhanced T1WI within the dural sinus...

Acute liver failure is a rare but life-threatening disease that can lead to progressive encephalopathy, intracranial hypertension, and multiorgan failure. In the developed world, the most common cause remains acetaminophen overdose, but there are still many cases in which there is acute liver failure of unknown etiology. The mainstay of acute liver failure management remains supportive care in the critical care setting. If supportive treatment does not stabilize the disease process, the patient may require emergent liver transplantation...

Traumatic brain injury (TBI) is a prominent public health issue that has a significant negative impact on patients and their family members. It is the leading cause of mortality and disability among young (below 50 years old) individuals. Intracranial hypertension (ICH) remains the single most difficult therapeutic challenge for the management of severe TBI. Therapeutic hypothermia may reduce intracranial hypertension and improve patient outcomes; however, the use of hypothermia is controversial. It has been reported that therapeutic hypothermia elicits no therapeutic benefit for patients with TBI...

BACKGROUND: Herpes simplex encephalitis (HSE) is the most frequent sporadic encephalitis in the world. In severe cases of HSE, the pathology usually progresses with an increase in intracranial pressure secondary to cerebral edema and/or hemorrhagic necrosis. Currently no high-power studies exist regarding the management of severe HSE and most of the papers reported in the literature are case reports. Decompressive craniectomy, effective in some cases of pharmaco-resistant intracranial hypertension (ICH) resulting from other causes, may be suggested in severe HSE, with several good results reported in the literature...
