Nada MG, Libda YI, Gohary MM, Dessouky R. Pediatric posterior reversible encephalopathy syndrome: Can MR imaging features predict outcomes in non-oncologic patients? Eur J Radiol 2024; 170:111214. [PMID: 38007856 DOI: 10.1016/j.ejrad.2023.111214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 08/09/2023] [Accepted: 11/20/2023] [Indexed: 11/28/2023]
Abstract
PURPOSE Identify MR features predictive of poor outcomes in non-oncologic pediatric PRES. METHOD A six-year search of all non-oncologic pediatric patients with clinical and MR features of PRES was performed. Modified Rankin scores were used to classify clinical outcomes into good versus poor, then clinical and MR features were compared among groups. Univariate and multivariate analysis was performed to identify MR predictors of poor outcomes for various imaging features, and p-values < 0.05 were considered statistically significant. RESULTS One hundred and forty-one patients (mean age 10.1 ± 3.0 years, male to female ratio 1:1.1) were included. Clinically, nephrotic syndrome (p = 0.03), focal deficits (p = 0.04), longer hospitalization (p < 0.001), and mechanical ventilation (p < 0.001) were significantly associated with poor outcomes. Univariate analysis revealed that deep grey matter nuclei (OR = 5.29, 95 % CI: 1.6-18.0) and cerebellar edema patterns (OR = 3.49, 95 % CI: 1.3-9.5), cytotoxic edema (OR = 63.6, 95 % CI:16.5-244.2), hemorrhage (OR = 16.58, 95 % CI: 4.3-64.2), and severe PRES patterns (OR = 11.0, 95 % CI: 3.5-34.7) on MR were all significantly associated with poor outcomes (p-values = 0.008 and 0.014, <0.001, <0.001, and < 0.001, respectively). This remained true for cytotoxic edema (OR = 84.26, 95 % CI: 17.3-410.9, p-value < 0.001) and hemorrhage (OR = 44.56, 95 % CI: 6.9-289.7, p-value < 0.001) on multivariate analysis. CONCLUSION Diffusion restriction and hemorrhage on initial MR scans were the two independent predictors of poor outcomes in non-oncologic pediatric patients.

Posterior reversible encephalopathy syndrome in children with malignancies - a single-center retrospective study. Front Neurol 2023; 14:1261075. [PMID: 38020647 PMCID: PMC10656676 DOI: 10.3389/fneur.2023.1261075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 10/23/2023] [Indexed: 12/01/2023] Open
Abstract
Background Posterior reversible encephalopathy syndrome (PRES) diagnosis relies on clinical and radiological characteristics. Clinical manifestations include focal neurologic deficits, hemiparesis, seizures with symptoms of intracranial hypertension, headache, nausea, vomiting, and visual field disturbances. The majority of patients have typical changes in magnetic resonance imaging. The epidemiology and outcomes of PRES in the pediatric cancer population have not been well described. Most of the available data are from retrospective analyses. Objective The aim of our study was to evaluate the clinical and radiological presentation as well as the outcome of PRES in children treated for cancers in a single center. Methods We analyzed data from 1,053 patients diagnosed with malignancies in a single center over 15 years to determine the incidence of PRES. Results 19/1053 (1.8%) patients developed PRES. The diagnosis was accompanied by a range of clinical symptoms including hypertension, seizures, altered mental status, and headaches. Magnetic resonance imaging was performed in all patients, and 14/19 (73.7%) exhibited typical findings consistent with PRES. Four patients (21.0%) required treatment in the Intensive Care Unit. Conclusion Posterior reversible encephalopathy syndrome (PRES) is a rare but significant complication in children with cancer.There is a clear need to establish clinical criteria for PRES to improve the diagnosis and treatment of patients with PRES, particularly in the pediatric oncological population.Further studies are needed to identify the risk factors for recurrent PRES, particularly in pediatric cancer patients undergoing chemotherapy or immunosuppressive treatment.

Paediatric posterior reversible encephalopathy syndrome: is there an association of blood pressure with imaging severity and atypical magnetic resonance characteristics? Pediatr Radiol 2022; 52:2610-2619. [PMID: 35723697 DOI: 10.1007/s00247-022-05400-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 04/26/2022] [Accepted: 05/06/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is relatively uncommon in paediatric patients; however, its pathophysiology remains obscure. OBJECTIVE The aims of this study were to find an association or correlation between (1) blood pressures and (2) imaging severity and the presence of atypical imaging features in children with PRES. MATERIALS AND METHODS We performed a retrospective cross-sectional evaluation in children diagnosed with PRES. We reviewed radiologic findings along with each patient's clinical profile and outcome. We categorised imaging severity into mild, moderate and severe, and assessed the MR imaging pattern, enhancement and diffusion restriction for each child. We assessed both associations and correlations between variables using the chi-square test, Cramer V and Kendall tau b. RESULTS A total of 63 children met the inclusion criteria (31 boys; mean age 9.7 years). A total of 42 children (67%) had an elevated blood pressure. Imaging showed parieto-occipital lobe involvement pattern in 24 (38%) children, frontal lobe pattern in 25 (40%) and cerebellar involvement in 12 (19%). Three (5%) had haemorrhage, 15 (24%) had contrast enhancement and 19 (30%) had positive diffusion restriction (cytotoxic oedema). We found no statistically significant association between imaging severity and blood pressures (P=0.11), nor any association between blood pressure and atypical imaging findings such as diffusion restriction (P=0.1), enhancement (P=0.11) or haemorrhage (P=0.33). CONCLUSION According to our results, there is no statistically significant association or correlation between blood pressure and either imaging severity or atypical imaging features in children with PRES. Further prospective studies are warranted.

Abstract
BACKGROUND AND AIM Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological syndrome characterized by a neurotoxic state with vasogenic edema. We studied the clinical profile, predisposing factors, imaging features, and outcome of PRES in children receiving treatment for hematolymphoid malignancies. METHODS Retrospective analysis of the clinical data and radiological features of patients with PRES diagnosed between June 2014 and December 2019. RESULTS Fifty-two patients (boy: girl = 3:1) were diagnosed with PRES during the study period with a median age of 11 (range:1-15) years. Primary diagnoses were acute leukemias (n = 42), non-Hodgkin lymphoma (n = 8), Hodgkin lymphoma (n = 1), and Langerhan's cell histiocytosis (n = 1). Most common presenting symptoms were seizures (n = 52), altered sensorium (n = 42), headache (n = 39), and visual disturbances (n = 8). Hypertension at time of diagnosis was noted in 50 (96%) patients. Classic hyper-intense lesions on FLAIR and diffusion weighed (DW) images were noted in parieto-occipital region in 39 patients (75%). Central PRES involving basal ganglia was seen in 3 (6%) patients. A subsequent neuro-imaging was done in 18 patients (MRI: 13; CT: 5) at a median interval of 16.2 weeks. Neurological sequelae were observed in 10 (19%) patients, whereas 1 succumbed due to PRES. CONCLUSIONS PRES is an important clinico-radiological syndrome in patients undergoing chemotherapy for hematological malignancies. High index of suspicion, early diffusion-weighted images on MRI in children with classic symptoms help in early diagnosis. A small minority of patients may develop long-term sequelae.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is receiving increasing recognition in pediatrics. However, comparisons between PRES in pediatric oncology and post-bone marrow transplantation (BMT) are lacking. Therefore, we aimed to describe the risk factors and clinical and radiological features of PRES and investigate the differences between PRES in pediatric oncology and post-BMT. The PRES data of 13 patients from our center were combined with those of 217 cases from the PubMed, Scopus, and Web of Science databases. The patients were divided into either an oncology or a post-BMT group. We included 230 patients in the analysis, 26.1% of whom belonged to the post-BMT group. Oncology patients developed PRES at a younger age (p = 0.010) and were more likely to develop encephalopathy (p = 0.004). Systemic hypertension (S-HTN) preceding PRES occurred in 43.5% (66/154) of patients. Post-BMT patients were more likely to have S-HTN (p = 0.003). Cyclosporine levels were detected in 37 patients; 40.5% had supra-therapeutic levels. The radiological findings were atypical in 74.3% of patients, and delayed repeated imaging increased the occurrence of resolution (p = 0.004). Sixteen (7%) patients developed PRES recurrence after a median of 8 weeks, with the between-group difference being non-significant. Oncology patients were more likely to develop chronic epilepsy, while BMT patients were more likely to develop rare neurologic abnormalities (p < 0.001). In conclusion, atypical clinical presentation and imaging findings should not hinder the diagnosis of PRES. S-HTN is a risk factor, particularly in post-BMT patients. Supra-therapeutic levels of cyclosporine and previous exposure to immunosuppression did not increase the risk of recurrence.

Abstract
Posterior reversible leukoencephalopathy syndrome (PRES) is a rare entity among children, characterised by acute neurological symptoms and radiological findings. The role of clinical symptoms and neuroimaging in predicting the prognosis of PRES have not been well-characterised. A retrospective descriptive study of children with PRES, admitted to a Paediatric Intensive Care Unit during a 10-year period, was performed to describe its characteristics, compare the accuracy of computed tomography (CT) scan and MRI on diagnosis and identify prognostic factors on paediatric population. Sixteen cases were identified. Most patients (13; 81%) presented underlying disorders, including malignancies (5; 31%), chronic kidney disease (3; 19%) and post-transplant status (3; 19%). Hypertension (15; 94%) was the most common trigger. All patients had seizures, 9 patients (56%) altered state of consciousness, 8 (50%) headache. CT scan was performed in 15 patients (94%) and MRI in 13 (81%); 1 patient underwent only MRI. MRI allows the identification of new areas of vasogenic oedema and a correct diagnosis of PRES when CT scan was inconclusive. Two patients (13%) remained with neurological sequelae and one died. In two patients (13%) cognitive disorders (specific learning disorder, intellectual disability, motor tic disorder) were diagnosed during follow-up period. Clinical presentation was not statistically associated with outcome. Also, atypical neuroimaging (haemorrhagic and unilateral lesions) were not statistically related with poor neurological or cognitive outcome. However, prospective studies with a larger cohort are needed to establish prognostic factors of PRES in the paediatric population.

Abstract
INTRODUCTION PRES, as a complication of juvenile lupus, is rarely reported in the literature. In this study, six juvenile lupus patients admitted with diagnosis of PRES were assessed on the basis of clinical characteristics, imaging findings, disease activity status, treatment response and prognosis. METHODOLOGY Six juvenile (≤ 16 years) lupus patients with a diagnosis of PRES were included. Demographic, clinical, and laboratory features and outcomes of all six patients were noted. Literature review was performed on PubMed search forum. Search terms in English included Juvenile SLE, Lupus and PRES. RESULT The youngest patient was seven years old while the oldest was sixteen years. All patients had history of lupus nephritis , presented with seizure and hypertension. In imaging, four out of six patients had hyperintensities in atypical distribution suggesting atypical PRES. All the patients had significant clinical recovery with resolution of hyperintensities in five out of six patients on repeat imaging. CONCLUSION Juvenile lupus with PRES is considered an unusual neurologic manifestation triggered by multiple factors. It can be stipulated that PRES in juvenile lupus cases often remain undiagnosed. Early suspicion and treatment institution with reversal of triggers can result in a favorable outcome in these patients.

Abstract
The etiology and outcomes of posterior reversible encephalopathy syndrome (PRES) in children with cancer are not well understood. We aim to determine the incidence of PRES, describe associated morbidity and mortality, and better understand risk factors in this patient population. A total of 473 children with a hematologic malignancy or postallogeneic hematopoietic cell transplantation between June 2015 and June 2020 were screened for PRES to determine incidence and whether age or underlying diagnosis are associated with development of PRES. We conducted a case-control study to evaluate whether comorbidities or chemotherapeutic agents are associated with PRES. Children with PRES were matched with 2 controls based on age and underlying diagnosis to identify additional risk factors. Fourteen patients developed PRES, with an incidence of 5.9/1000 people/year. Those diagnosed with PRES had commonly described PRES symptoms: hypertension, seizures, nausea/vomiting, altered mental status, and headaches. All patients received an magnetic resonance imaging, and most had findings consistent with PRES. Hematopoietic cell transplantation was associated with the development of PRES. The use of Etoposide was associated with PRES but comorbidities, steroids and calcineurin inhibitors were not. While PRES was infrequent in this population, it is associated with high morbidity and mortality, with ICU admissions and an overall hospital mortality, because of secondary causes, of 29%.

Abstract
ABSTRACT Numerous factors make the initial diagnostic evaluation of children with suspected arterial ischemic stroke (AIS) a relatively unsettling challenge, even for the experienced stroke specialist. The low frequency of pediatric AIS, diversity of unique age-oriented stroke phenotypes, and unconventional approaches required for diagnosis and treatment all contribute difficulty to the process. This review aims to outline important features that differentiate pediatric AIS from adult AIS and provide practical strategies that will assist the stroke specialist with diagnostic decision making in the initial phase of care.

Abstract
AIM The aim of this study was to describe the characteristics of Posterior Reversible Encephalopathy Syndrome (PRES) in infants and young children (<6 years) and to compare them with the older pediatric population affected by PRES. METHODS we retrospectively reviewed records of 111 children (0-17 years) diagnosed with PRES from 2000 to 2018 in 6 referral pediatric hospitals in Italy. The clinical, radiological and EEG features, as well as intensive care unit (ICU) admission rate and outcome of children aged <6 years were compared to those of older children (6-17 years). Factors associated with ICU admission in the whole pediatric cohort with PRES were also evaluated. RESULTS Twenty-nine patients younger than 6 years (26%) were enrolled with a median age at onset of PRES of 4 years (range: 6 months-5 years). Epileptic seizures were the most frequent presentation at the disease onset (27/29 patients). Status epilepticus (SE) was observed in 21/29 patients: in detail, 11 developed convulsive SE and 10 presented nonconvulsive SE (NCSE). SE was more frequent in children <6 years compared with older children (72% vs 45%) as well as NCSE (35% vs 10%). Seventeen children aged <6 years required ICU admission. Prevalence of ICU admissions was higher within younger population compared to older (59% vs 37%). In the whole study population SE was significantly associated with ICU admission (p = 0.001). CONCLUSIONS PRES in children < 6 years differs from older children in clinical presentation suggesting a more severe presentation at younger age.

Posterior Reversible Encephalopathy Syndrome after Allogeneic Stem Cell Transplantation in Pediatric Patients with Fanconi Anemia, a Prospective Study. Biol Blood Marrow Transplant 2020; 26:e316-e321. [PMID: 32860910 DOI: 10.1016/j.bbmt.2020.08.021] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 07/20/2020] [Accepted: 08/16/2020] [Indexed: 12/15/2022]
Abstract
Posterior reversible encephalopathy syndrome (PRES) is one of the most common neurologic complications following hematopoietic stem cell transplantation (HSCT). We aimed to evaluate the incidence, clinical, and imaging features of PRES in pediatric patients with Fanconi anemia (FA) following HSCT. This prospective study included all post-HSCT patients with underlying FA disease between 2014 and 2017. Brain computed tomography scan and magnetic resonance imaging (MRI) were performed in all individuals who developed neurologic symptoms. PRES was diagnosed based on clinic-radiological evidence. Follow-up MRI was performed in all patients with PRES within two months. Forty-one patients with FA (28 males; mean age, 8.19 ± 3.25 years) were enrolled. Out of 15 patients with acute neurologic symptoms, PRES was diagnosed in 9 individuals (21.95% of the total cohort). The occurrence of PRES was significantly higher in patients who had a donor with a 1-locus mismatch (P= .02). Donor relation, stem cell source, and graft-versus-host disease grade did not have any significant association with the development of PRES. MRI showed asymmetric vasogenic edema in 5 patients, an overt infarct in 1 patient, and foci of microhemorrhages in 3 patients, 1 of whom developed a hemorrhagic infarct. This patient died shortly, and persistent microhemorrhages were noted in the other 2 patients. Our findings demonstrate a greater risk of developing PRES after HSCT in patients with FA compared with those with other diseases (21.95% versus 1% to 10%), and in contrast to its term, it might be irreversible and has adverse effects on HSCT outcomes. The increased vascular and endothelial fragility in FA may contribute to the higher frequency of PRES in these individuals.

Abstract
Relapsing demyelinating syndromes (RDS) in children encompass a diverse spectrum of entities including multiple sclerosis (MS) acute disseminated encephalomyelitis (ADEM), aquaporin-4 antibody associated neuromyelitis optica spectrum disorder (AQP4-NMOSD) and myelin oligodendrocyte glycoprotein antibody disease (MOG-AD). In addition to these, there are “antibody-negative” demyelinating syndromes which are yet to be fully characterized and defined. The paucity of specific biomarkers and overlap in clinical presentations makes the distinction between these disease entities difficult at initial presentation and, as such, there is a heavy reliance on magnetic resonance imaging (MRI) findings to satisfy the criteria for treatment initiation and optimization. Misdiagnosis is not uncommon and is usually related to the inaccurate application of criteria or failure to identify potential clinical and radiological mimics. It is also notable that there are instances where AQP4 and MOG antibody testing may be falsely negative during initial clinical episodes, further complicating the issue. This article illustrates the typical clinico-radiological phenotypes associated with the known pediatric RDS at presentation and describes the neuroimaging mimics of these using a pattern-based approach in the brain, optic nerves, and spinal cord. Practical guidance on key distinguishing features in the form of clinical and radiological red flags are incorporated. A subsection on clinical mimics with characteristic imaging patterns that assist in establishing alternative diagnoses is also included.

Abstract
AbstractThe posterior reversible encephalopathy syndrome was characterized by Hinchey and colleagues in the 1990s. The condition frequently afflicts patients suffering from hematologic and solid organ malignancy and individuals undergoing transplantation. Cases are more frequently described in the adult population compared with children. In the pediatric population, malignancy, transplantation, renal disease, and hypertension represent the most common etiologies. Theories on pathogenesis have centered upon cerebrovascular dysautoregulation with increases in blood–brain barrier permeability. This generates vasogenic edema of the cerebral parenchyma and consequent neurologic deficits. The parietal and occipital lobes are affected with greatest prevalence, though frontal and temporal lobe involvement is frequent, and that of the contents of the infratentorial posterior cranial fossa are occasionally described. The clinical presentation involves a characteristic constellation of neurologic signs and symptoms, most typically inclusive of headache, visual-field disturbances, abnormalities of visual acuity, and seizures. Supportive care, withdrawal of the offending agent, antihypertensive therapy, and prophylactic anticonvulsants affect convalescence in majority of cases. The principal challenge lies in identifying the responsible agent precipitating the condition in patients with malignancy and those having undergone transplantation and thus deciding which medication among a multidrug treatment regimen to withhold, the duration of drug cessation required to effect clinical resolution, and the safety of resuming treatment with the compound. We accordingly reviewed and evaluated the literature discussing the posterior reversible encephalopathy syndrome in children.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is a novel clinicoradiological syndrome characterized by convulsions, headache, altered mentality, and impaired vision, which are usually accompanied by hypertension. As its nomination, PRES is usually diagnosed according to the presence of typical neuroimage showing vasogenic edema predominately involving the posterior brain area. With the widespread utilization of magnetic resonance imaging (MRI), PRES is becoming more perceptible in different medical fields. Compared to adult cases, childhood PRES seems to have a broader clinical and neuroradiological spectrum. PRES can be associated with various underlying comorbidities, medication use, and therapeutic modalities in children with diverse neurological manifestations. Moreover, pediatric patients with PRES have a more significant propensity for atypical MRI findings beyond the typically posterior cerebral areas. The knowledge of typical and atypical presentations in children is essential to avoid misdiagnosing or missing PRES, which is a potentially treatable entity. Early supportive care is the mainstay of treatment, with particular attention to the treatment of hypertension with rigorous attention to all body systems. Prompt identification and symptom-directed management are imperative to achieve a reversible prognosis in childhood PRES. Future studies specially designed for the child population are required to determine potential outcome predictors, and further, to develop novel strategies of neuroprotection in childhood PRES.

Abstract
IMPORTANCE The pathophysiological mechanisms of Posterior Reversible Encephalopathy Syndrome (PRES) and related seizures remain poorly understood. The prevalence and clinical significance of nonconvulsive seizures (NCSz) and related epileptiform patterns during continuous electroencephalography monitoring (CEEG) in PRES have not been well described. OBJECTIVE To report the prevalence, characteristics and risk factors for NCSz and related highly epileptiform patterns in patients with PRES, and to determine their relation to imaging abnormalities and outcome. DESIGN, SETTING AND PARTICIPANTS From a prospective CEEG database, we retrospectively identified patients with PRES and reviewed their medical charts. Based on CEEG findings, we designed a retrospective cohort study comparing two groups defined based on the presence or the absence of NCSz and/or periodic discharges (PDs). MAIN OUTCOMES AND MEASURES The prevalence and risk factors for PDs and NCSz, description of EEG and magnetic resonance imaging (MRI) abnormalities and functional outcome as measured by the Glasgow Outcome Scale (GOS) at hospital discharge. RESULTS Among 37 eligible patients, 23 (62%) had PDs or NCSz. The presence of NCSz was associated with the presence of PDs (15/22 vs. 1/15; p = 0.0002). NCSz and PDs were usually either lateralized or bilateral independent and predominated in the posterior regions. No clinical features were associated with the occurrence of PDs or NCSz. Cortical restricted diffusion on MRI was more frequent in the PDs/NCSz group (17/23 vs. 1/14; p < 0.001). PDs/NCSz were associated with worse outcome, with 3 deaths vs. 0 in the no PDs/NCSz group and fewer cases with low disability (4 vs. 9 cases with GOS = 5, p < 0.04). CONCLUSIONS AND RELEVANCE Our results reveal a high prevalence of NCSz and PDs in critically ill patients with PRES and an association with restricted diffusion and worse outcome, whether treating or preventing these EEG findings can improve outcome requires further research.

Abstract
PURPOSE The aim of this study was to evaluate seizure outcome in children with hematological malignancies and PRES and to identify prognostic factors that could help manage the syndrome. METHOD We retrospectively reviewed the report data of 21 patients diagnosed with hematological malignancy or aplastic anemia and PRES between 2008 and 2018. Basic demographic data, oncology treatment, presymptomatic hypertension before PRES manifestation, neurological status, seizure type, and EEG and MRI findings at PRES onset and at the one-year follow-up visit were studied. Patients who developed remote symptomatic seizures or epilepsy were identified. RESULTS We included 21 children (11 females and 10 males) in the study. Sixteen patients (76.2%) were diagnosed with ALL and the rest individually with AML, CML, T-lymphoma, Burkitt lymphoma, and severe aplastic anemia. Presymptomatic hypertension (PSH) was evaluated in 19 patients and was present in 18 (94.7%). The duration was 9 h and more in 16 patients (88.8%); the severity was grade II in 12 patients (66.7%). Seizures as the initial symptom of PRES were present in 17 patients (80.9%). Four patients (19.0%) were assessed with remote symptomatic seizures. Two of them (9.5%) had ongoing seizures at the one-year follow-up visit and were diagnosed with epilepsy. The presence of gliosis on follow-up MRI indicated worse outcome with development of epilepsy (without statistical significance). CONCLUSIONS PRES syndrome has an overall good prognosis and the evolution to epilepsy is rare. The severity and duration of PSH or seizure severity and EEG findings at PRES onsetwere not associated with worse neurological outcomes in this study.

Abstract
PURPOSE OF REVIEW Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiological syndrome characterized by acute cerebral endotheliopathy with consecutive disruption of the blood-brain barrier and vasogenic edema. Since its first description in 1996, PRES is increasingly recognized. However, many aspects of this syndrome with its wide spectrum of clinical and radiological features are still incompletely understood. In this review, possible pathophysiological mechanisms, approaches to diagnosis, recent study results on outcome, and future directions of research are described. RECENT FINDINGS Clinical manifestations of PRES include seizures, headache, visual disturbances, altered mental state, and more rarely hemiparesis or aphasia. Vasogenic edema predominantly occurs in the parieto-occipital region, but lesions affecting formerly called 'atypical' regions such as frontal lobe, cerebellum, or basal ganglia are common. If treated early and adequately, that is by removal of the underlying cause, PRES has a favorable prognosis, but neurological residual symptoms and even mortality can occur, particularly in patients with complications such as intracranial hemorrhage. SUMMARY In summary, validated diagnostic criteria and algorithms are warranted to standardize the diagnosis of PRES. This is essential for further research and future prospective studies that should investigate risk factors for unfavorable outcome and identify the roles of imaging features, clinical symptoms, and other biomarkers in predicting outcome.

Abstract
pLT is a highly standardized therapy for children with end-stage liver disease and liver-based metabolic diseases. However, NCs after transplantation occur and especially younger children are considered as more vulnerable and susceptible to NCs. Up to now, detailed data particularly for the very young age group do not exist. We therefore retrospectively studied NCs in children after pLT under age of 24 months. Forty children aged between 19 days and 22 months were evaluated according to type of NC and potential risk factors. NCs occurred in 8/40 patients (20%). All experienced new-onset seizures and in 1/6 surviving patients, seizures evolved into epilepsy. Other NCs were intracerebral abscess (1/8 patients) and subdural hemorrhage (1/8 patients). The overall 3-year mortality rate was 10% (4/40 patients). Significant risk factors for NCs and therefore seizures were HAT (P = 0.020), total surgery time (P = 0.009), retransplantation (P < 0.001), period of catecholamine therapy (P = 0.024), period of mechanical ventilation (P = 0.014), and period of sedation (P = 0.010). Our study is the first to provide detailed information on NCs after pLT in children under 24 months of age. The incidence of NCs in this particular group of very young patients was not increased compared to previously published data of children of all ages. Main NC was new-onset seizure. In the surviving infants, prognosis of seizure was excellent and the risk of developing epilepsy was low. Even more, the occurrence of NCs did not significantly affect mortality or survival in this particular age group.

Abstract
INTRODUCTION Posterior reversible leukoencephalopathy syndrome (PRES) is a clinical syndrome of varying aetiologies, characterised by acute neurological symptoms of brain dysfunction with MRI abnormalities in posterior cerebral white and grey matter. In most cases, symptoms resolve without neurological consequences. AIM The aim of this paper is the analysis of predisposing factors, clinical outcomes and radiological features of PRES in eight children with hemato-oncological disease. MATERIAL AND METHODS We analysed the medical records of eight hemato-oncological patients aged from 3.0 to 16.1 years. The mean of age at primary diagnosis was 8.5 years. RESULTS All patients had both clinical and radiological PRES features. Seven out of eight underwent intensive chemotherapy regimens. Time elapsed from start of treatment to the occurrence of PRES ranged from 6 to 556 days. In one case, PRES occurred before chemotherapy and was the first symptom of cancer. Most (six of eight) patients had history of hypertension (> 95pc) and some (two of eight) occurred electrolyte imbalance-mainly hypomagnesaemia. Patients presented headache (seven of eight), disturbances of consciousness (six of eight), seizures (six of eight), visual changes (four of eight) and vomiting (three of eight). MRI demonstrated abnormalities in seven children: typical cerebral oedema in the white matter of the occipital to the parietal lobes. Most patient lesions in the MRI shrunk after 4 weeks, and clinical symptoms of PRES disappeared completely within a few hours to few days. CONCLUSION PRES may complicate oncological treatment in children. Hypertension is the most important risk factor of PRES. PRES should be included in differential diagnosis in all patients with acute neurological symptoms.

[PMID: 28417553 DOI: 10.1002/pbc.26531] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2016] [Revised: 02/20/2017] [Accepted: 02/23/2017] [Indexed: 12/26/2022]
Abstract
BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is a distinct clinico-radiologic entity that can occur following allogeneic hematopoietic stem cell transplantation, often in the context of treatment with calcineurin inhibitors (CNIs). PROCEDURE We describe the results of CNI-free management of 14 children with PRES and review the clinical and radiologic manifestations of their presentation. RESULTS Discontinuation of CNIs usually resulted in remission of PRES, but patients with established graft versus host disease (GVHD) at the time when treatment was changed often experienced progressive GVHD despite administration of immune suppressive and modulating treatments. All but three patients experienced full neurologic recovery. Nine children died as a result of either GVHD, disease relapse, or severe infection. CONCLUSIONS Discontinuation of CNIs results in neurologic improvement in most cases, but superior alternative immune modulatory treatment is needed to prevent progression of established GVHD.

Abstract
We characterized a cohort of patients with posterior reversible encephalopathy syndrome with spinal cord involvement. We encountered 2 children and identified an additional 19 patients from the internet databases. Of the 21 patients analyzed, 8 were children. The mean peak systolic blood pressure in adults was significantly higher than in children (221.8 ± 14.3 vs 191.4 ± 31.3 mm Hg; P < .01). Regardless of age, the most common clinical symptom was headache (90%) and the least common clinical symptom was seizures (28%). Atypical neuroimaging was more common in children (63%) than in adults (8%). Abnormal cerebrospinal fluid results were frequently found in children (83%). All children recovered uneventfully, but 3 adults had sequelae. A broader clinicoradiologic spectrum makes the diagnosis of children more complex than in adults. Awareness of the atypical features with a meticulous management of hypertension is imperative to avoid unnecessary invasive workups and to achieve an uneventful recovery.

Abstract
BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is an acute neurotoxic syndrome that, although characteristically reversible, can result in long-term disability. Our aim was to identify the clinical and radiological factors that are unique to children with PRES compared with adults with the syndrome in a single center. METHODS We retrospectively reviewed the clinical and radiological records of all patients with PRES admitted at a tertiary care medical center from 2007 to 2014. All patients who met the clinical and radiological criteria for PRES were dichotomized into children (less than 18 years) and adults (18 years or older) based on their age groups, and comparison of their baseline variables, clinical, laboratory, and imaging features was performed. RESULTS During this study period, 19 pediatric patients and 100 adult patients with PRES were identified. On univariate analysis, factors significantly associated with pediatric patients with the syndrome were multiorgan failure (84.2% vs 50%, P = 0.006), temporal lobe involvement (63.3% vs 39%, P = 0.04), restricted diffusion (42.1% vs 18%, P = 0.02), and less likelihood of cerebellar involvement (21.1% vs 57%, P = 0.004). On bivariate logistic regression analysis, all these factors remained significantly associated with pediatric PRES; multiorgan failure (odds ratio: 5.80, 95% confidence interval: 1.45 to 29.41, P = 0.03), temporal lobe involvement (odds ratio: 5.08, 95% confidence interval: 1.17 to 22.17, P = 0.03), restricted diffusion (odds ratio: 2.48, 95% confidence interval: 1.61 to 10.10, P = 0.02), and less likely to have cerebellar involvement (odds ratio: 0.08, 95% confidence interval: 0.002 to 0.39, P = 0.002). CONCLUSIONS Factors unique to PRES in children compared with adults include a greater propensity with multi-organ failure, involvement of the temporal lobe, and restricted diffusion on imaging.

Abstract
We are reporting a case of posterior reversible encephalopathy syndrome (PRES) developed in an unusual clinical scenario without the presence of the most described symptoms. PRES is a neurological and radiological syndrome described in many different clinical conditions. In children it has been mostly reported in association with hematological and renal disorders.Our patient was a 15 years old boy, admitted to our intensive care unit for pancreatitis after blunt abdominal trauma.During the stay in the intensive care unit, he underwent multiple abdominal surgical interventions for pancreatitis complications. He had a difficult management of analgesia and sedation, being often agitated with high arterial pressure, and he developed a bacterial peritonitis. After 29 days his neurological conditions abruptly worsened with neuroimaging findings consistent with PRES. His clinical conditions progressively improved after sedation and arterial pressure control.He was discharged at home with complete resolution of the neurological and imaging signs 2 months later.The pathophysiology of PRES is controversial and involves disordered autoregulation ascribable to hypertension and endothelial dysfunction. In this case both hypertension and endothelial activation, triggered by sepsis and pancreatitis, could represent the culprits of PRES onset. Even if there is no specific treatment for this condition, a diagnosis is mandatory to start antihypertensive and supportive treatment. We are therefore suggesting to consider PRES in the differential diagnosis of a neurological deterioration preceded by hypertension and/or septic state, even without other "typical" clinical features.

Abstract
INTRODUCTION In 1996, Hinchey and colleagues coined the term "Posterior reversible encephalopathy syndrome" (PRES) to describe a condition seen in patients with acute neurological symptoms and reversible subcortical vasogenic edema predominantly involving parieto-occipital areas demonstrated in brain MRI. The occurrence of this phenomenon after surgical resection of CNS tumors is typically linked to pediatric cases. MATERIAL AND METHODS Two new cases of PRES after posterior fossa surgery are reported. A thorough review of the literature is carried out with the purpose of updating and summarizing the main features regarding PRES in similar cases. Seven cases of PRES after resection of a posterior fossa tumor have been hitherto reported (4 patients were <20 years old). There is another pediatric case described after a ventriculoperitoneal shunting procedure in a patient with fourth ventricle ependymoma. Two resected tumors were ependymomas, 2 hemangiopericytomas in one patient, 1 pilocyticastrocytoma, 1 vestibular schwannoma, and 1 of the reported cases did not describe the final pathology diagnosis. CASE REPORTS We present 2 new cases of PRES after surgical resection of a posterior fossa tumor (medulloblastoma in case 1 and ependymoma in case 2) in pediatric patients. Case 1 developed delayed seizures and altered mental status(10 days after surgical resection) after receiving treatment with bromocriptine for cerebellar mutism. Case 2 presented with generalized seizures and altered mental status within the first 48 postoperative hours followed by right hemiparesis. Both patients fully recovered and returned to neurological baseline status. A thorough review of the literature was carried out with the purpose of updating and summarizing the main features regarding PRES in similar cases. CONCLUSIONS We report 2 new pediatric cases of posterior reversible encephalopathy syndrome (PRES) that developed after surgical resection of a posterior fossa tumor. Appropriate management includes supportive measures, antihypertensive agents, and antiepileptic drugs, if needed. Full recovery is the most likely outcome in line with previous articles.

Abstract
BACKGROUND Diagnosis of posterior reversible encephalopathy syndrome (PRES) requires presence of headache, seizures, impaired vision, or altered mentation accompanied by specific imaging findings. We aimed to study long-term clinical and radiologic outcome of PRES in children with cancer to augment limited available data. PROCEDURE Retrospective review of children with cancer who were diagnosed with PRES. RESULTS We identified PRES in 21 males and 16 females among 5,217 children treated during the study period. Median time from cancer diagnosis to PRES was 6.6 months in 25 leukemia (1.6%), five brain tumor (0.3%), and seven other solid tumor (0.4%) patients; P = <0.0001 for leukemia versus all other tumors. Symptoms included seizures (97%), headaches (40%), altered mentation (68%), and vision impairment (27%). Hypertension was seen in 97%, and steroids use was seen in 78%. Headaches, visual disturbance, and mental status resolved within a median of <3 days, whereas epilepsy developed in 19%. T2 hyperintense signal was present in 100% of occipital, 47% of temporal, 75% of parietal, and 55% of frontal lobes, as well as 22% of cerebellum and 5% of basal ganglia. Follow-up magnetic resonance imaging (MRI) in 34 patients showed partial or complete T2 resolution in 79%, development of laminar necrosis in five, microhemorrhages in six, and focal atrophy in three. CONCLUSION PRES in children is more common in hematological malignancy compared with other tumors and is associated with hypertension and steroid use. Seizure is the most common acute manifestation. Most MRI changes resolve, but persistent imaging abnormality and epilepsy may develop in a significant minority.

Abstract
Our aim was to compare our South African cohort of systemic lupus erythematosus (SLE) and posterior reversible encephalopathy syndrome (PRES) with other published series. We reviewed the records of 10 patients with SLE and PRES seen over a 10-year period and their demographic data, clinical manifestations, laboratory tests, imaging findings, and outcome were recorded. We identified 10 females who included six Indians, three mixed ethnicity, and one African Black. Three patients had PRES at the onset of SLE. The most common manifestations at presentation were seizures (100 %), hypertension (80 %), and altered mental state (50 %). On neuroimaging, nine patients had bilateral involvement, and the occipital (90 %), parietal (90 %), and frontal lobes (50 %) were most commonly involved. The risk factors for PRES were disease activity (90 %), renal disease (80 %) and hypertension (80 %). Ninety percent of the patients were on immunosuppressive therapy. Immunosuppressive therapy was increased in six patients (60 %), continued in two and reduced in two patients after the diagnosis of PRES. Seven patients recovered completely and three patients died from co-morbidities. A review of the larger case series of SLE and PRES showed that the presentation and neuroimaging findings were similar; most patients had active disease at the time of PRES and the majority of patients required intensification of immunosuppressive therapy. We have shown that the majority of patients with SLE have active disease at the time of PRES, and they require an increase in their immunosuppressive therapy.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is a clinical syndrome characterized by vision changes, altered mental status, and seizures, typically caused by an acute rise in blood pressure. PRES has been reported after hematopoietic stem cell transplantation (HSCT) in association with hypertension from calcineurin inhibitors and corticosteroids. The imaging evaluation of PRES after HSCT in children and young adults has not been well described. We performed a retrospective review of all HSCT recipients presenting to the intensive care unit with new neurologic symptoms. A neuroradiologist reviewed all radiologic images and compared computed tomography (CT) versus magnetic resonance imaging (MRI) findings indicative of diagnosis of PRES. Alternative imaging diagnoses explaining the patients' symptoms were also recorded. Fifty-four transplant recipients were admitted to the intensive care unit with new neurologic symptoms. Thirty-nine percent (21 of 54) of subjects had imaging findings consistent with PRES, 24% (13 of 54) had imaging findings consistent with an alternative diagnosis, 9% (5 of 54) had a nonspecific finding, and 28% (15 of 54) had no acute imaging findings. PRES was diagnosed at a median of 49 days (interquartile range, 29 to 94) after HSCT. The presenting symptom for the majority of patients with PRES was seizures (86%), whereas 14% presented with acute encephalopathy. Ninety-five percent of subjects diagnosed with PRES (20 of 21) underwent a head CT as their initial imaging evaluation. CT scan was diagnostic of PRES in 40% (8 of 20). Subsequently, 16 patients underwent brain MRI with 12 additional patients being diagnosed with PRES on MRI. The median time elapsed between negative CT and a positive MRI examination was 20 hours (range, 3.6 hours to 9 days). CT serves as an excellent screening test for acute pathology, such as intracranial hemorrhage; however, it lacks sensitivity for the diagnosis of PRES. Patients with clinical symptoms suggestive of PRES who have a negative CT should be treated appropriately for PRES and should undergo MRI of the brain as soon as clinically stable to confirm the diagnosis.
