Objective: Encephalomalacia after traumatic brain injury (TBI) is one of the factors leading to epilepsy. In this study, magnetic resonance imaging (MRI) was used to explore the brain image features of epilepsy after traumatic encephalomalacia, and to provide objective evidence for predicting the possible occurrence of epilepsy after traumatic encephalomalacia. Methods: Two-hundred-fifty-two patients with traumatic encephalomalacia were prospectively enrolled in the study...

Five calves that had shown neurological symptoms within 9 days after birth were histopathologically diagnosed as encephalomalacia. Two calves showed bilateral laminar cerebrocortical necrosis and neuronal necrosis in the corpus striatum and hippocampus. Since the distributional pattern of the lesions was consistent with that of global ischemia in other species, the lesions were probably hypoxic/ischemic encephalopathy consistent with the history of dystocia and perinatal asphyxia. One calf also showed bilateral laminar cerebrocortical necrosis...

Brake cleaner liquid is commonly used for cleaning of engines and motor parts. The commercially available products usually contain mainly volatile organic compounds. As a consequence brake cleaner evaporates fast and almost completely from the cleaned surface. This case report presents a fatal accidental inhalation of brake cleaner liquid aerosols due to the attempted cleaning of a boat engine. A 16year old boy was found lifeless in the engine compartment of a boat engine. In close proximity to the body, the police found cleanings wipes soaked with brake cleaner as well as a pump spray bottle filled with brake cleaner...

In 2016, the highly pathogenic avian influenza (HPAI) H5N8 virus was detected in wild birds for the first time in Egypt. In the present study, we identified the HPAI virus H5N8 of clade 2.3.4.4 from domestic waterfowl in Egypt, suggesting its transmission to the domestic poultry from the migratory birds. Based on partial hemagglutinin (HA) gene sequence, this virus has a close genetic relationship with subtype H5N8 viruses circulating in Asia and Europe. Pathologically, H5N8 virus in hybrid duck induced nervous signs accompanied by encephalomalacia, hemorrhages, nonsuppurative encephalitis and nonsuppurative vasculitis...

Molybdenum cofactor deficiency is a rare metabolic disorder manifesting with early onset seizures, developmental delay, microcephaly, and spasticity. In this report, we describe a three-month-old infant with neonatal onset, poorly controlled seizures, developmental delay, microcephaly, spastic quadriparesis and visual insufficiency. Magnetic resonance imaging of brain had shown cystic encephalomalacia involving bilateral parieto-occipital lobe and elevated lactate in magnetic resonance spectroscopy. Restricted diffusion noted along the corticospinal tract in our case is a novel imaging finding in patients with molybdenum cofactor deficiency...

We present a case of a 56-year-old male with a history of perinatal intracerebral hemorrhage who presented to the emergency department after a witnessed new-onset generalized tonic-clonic seizure. Computerized tomography and magnetic resonance imaging of the head revealed a large frontal lobe porencephalic cyst, with encephalomalacia in the right parietal lobe and temporal lobe (the patient did not have any prior cranial imaging). The patient has subsequently remained seizure-free on levetiracetam. Porencephalic cyst is a rare condition of cerebrospinal fluid accumulation in the brain parenchyma that is usually related to perinatal vascular events...

Magnetic resonance imaging (MRI) is a powerful tool for visualizing traumatic brain injury(TBI)-related lesions. Trauma-induced encephalomalacia is frequently identified by its hyperintense appearance on fluid-attenuated inversion recovery (FLAIR) sequences. In addition to parenchymal lesions, TBI commonly results in cerebral microvascular injury, but its anatomic relationship to parenchymal encephalomalacia is not well characterized. The current study utilized a multimodal MRI protocol to assess microstructural tissue integrity [via mean diffusivity (MD) and fractional aniosotropy (FA)], and altered vascular function [via cerebral blood flow (CBF) and cerebral vascular reactivity (CVR)], within regions of visible encephalomalacia and normal appearing tissue in 27 chronic TBI (minimum 6 months after injury) subjects...

Because of the more frequent use of noninvasive imaging methods, arteriovenous malformation (AVM) are gaining more attention. Population based studies reveal that about 35% to 50% of patients with AVM initially present with hemorrhage. Prior hemorrhage is the most consistent risk factor for future hemorrhage, other risk factors include deep venous drainage pattern, deep location, and so on. Surgical interventions, including surgical excision, intravascular intervention, and stereotactic radiation, have been developed with the aim at eliminating this source of hemorrhage...

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...

Despite the availability of modern antibiotics, pneumococcal meningitis in both children and adults remains a severe disease-one known to frequently cause grave complications and residual disability. Although the appearance of arterial vasospasms in bacterial meningitis systematically has been investigated and reported on for adult patients, such research is lacking when it comes to infants. We report on a 4-week-old infant who, 6 days after onset of pneumococcal meningitis, suffered severe neurological deterioration with treatment-resistant seizures and coma...

The pathophysiology of drug-resistant pediatric epilepsy is unknown. Flow cytometric analysis of inflammatory leukocytes in resected brain tissues from 29 pediatric patients with genetic (focal cortical dysplasia) or acquired (encephalomalacia) epilepsy demonstrated significant brain infiltration of blood-borne inflammatory myeloid cells and memory CD4+ and CD8+ T cells. Significantly, proinflammatory (IL-17- and GM-CSF-producing) γδ T cells were concentrated in epileptogenic lesions, and their numbers positively correlated with disease severity...

Glioblastoma is the most common primary parenchymal brain malignancy, with median survival of less than one year. While there are likely multiple predisposing genetic and environmental factors in glioblastoma formation, chronic inflammation resulting from non-traumatic vascular brain injury is one proposed risk factor for oncogenesis. Here, we report two instances of glioblastoma arising within areas of encephalomalacia caused by remote vascular insults (one following aneurysmal subarachnoid hemorrhage and one following ischemic infarction), review the literature associating glioblastoma with prior brain injury, and discuss potential mechanisms for malignant transformation in injured brain tissue...

Vitamin E is a generic term frequently used to group together eight different molecules, namely: α-, β-, γ- and δ-tocopherol and the corresponding tocotrienols. The term tocopherol and eventually Vitamin E and its related activity was originally based on the capacity of countering foetal re-absorption in deficient rodents or the development of encephalomalacia in chickens. In humans, Vitamin E activity is generally considered to be solely related to the antioxidant properties of the tocolic chemical structure...

OBJECTIVE Epilepsy surgery is effective for lesional epilepsy, but it can be associated with significant morbidity when seizures originate from eloquent cortex that is resected. Here, the objective was to describe chronic subthreshold cortical stimulation and evaluate its early surgical safety profile in adult patients with epilepsy originating from seizure foci in cortex that is not amenable to resection. METHODS Adult patients with focal drug-resistant epilepsy underwent intracranial electroencephalography monitoring for evaluation of resection...

Structural neuroimaging of athletes who have sustained a sports-related concussion (SRC) can be viewed as either standard clinical imaging or with advanced neuroimaging methods that quantitatively assess brain structure. Negative findings from conventional computed tomography (CT) or magnetic resonance imaging (MRI) are the norm in SRC. Nonetheless, these conventional measures remain the first line of neuroimaging of the athlete as they do detect clinically significant pathologies, when present, such as hemorrhagic abnormalities in the form of hematomas, contusions and mircobleeds along with regions of focal encephalomalacia or other signal abnormalities, with CT best capable of detecting skull fractures...
