Abstract
Background:
Posterior reversible encephalopathy syndrome (PRES) is clinicoradiological disease entity characterized by headache, seizures, altered sensorium and corticalvisual loss with characteristic MRI features of subcortical white matter hyperintensities on T2W imaging. Though hypertension is a traditional hallmark of PRES, uncommon causes without hypertension have been described. We report an unusual such case without hypertension, precipitated by red cell transfusion.
Case Presentation:
A 40 years female received six units of packed cell transfusion for severe anemia (Hemoglobin 3.0 Gm %) transfused over 8 hours. She was having menorrhagia and was operated on for a hysterectomy. She developed a headache on the second postoperative day for five days and no cause was revealed in spite of extensive workup, including MRI brain and CSF study. On the sixth day, she had recurrent seizures followed by altered sensorium in the absence of hypertension. Her repeat MRI brain findings were consistent with PRES.
Conclusion:
We reviewed 25 cases, including the present one as PRES after the blood transfusion. 24 were females, and 16 of 19 developed PRES in the course of chronic anemia lasting over 1 month. Anemia was severe in 18 of 25 cases, with haemoglobin (Hb) levels < 4.0 Gm%. In 16 of 20 cases, Hb levels increased to 5 g/dl by red cell blood transfusion until the onset of PRES. On MRI brain, 23 of 25 cases showed vasogenic edema and 3 of 25 cases showed an irreversible neurological deficit. When treating severe chronic anemia rapid correction of Hb with blood transfusion, one should consider a possibility of PRES in post-transfusion neurological symptoms in spite of normal diagnostic workup.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is a rare neurological entity, typically manifested by reversible oedema in the parieto-occipital lobes. It is usually associated with primary hypertension, autoimmune diseases and immunosuppressants. Renal disease is an uncommon cause of PRES. We report a case of an 11-year-old boy with STimulator of INterferon Genes-associated vasculopathy with onset in infancy complicated by focal segmental glomerulosclerosis leading to hypertension and PRES. The patient presented with headache, acute bilateral visual loss and hypertension. Brain MRI showed atypical features revealed by parieto-occipital haemorrhage. The child improved few days after antihypertensive therapy. Follow-up MRI showed complete resolution of haemorrhage. It is important to keep high index of suspicion for the uncommon association of PRES with underlying kidney disease with or without immunosuppressive agents. This combination is the first to our knowledge to be described in paediatric population. Atypical MRI features such as haemorrhage should be kept in mind. Symptoms are reversible within days to weeks with early diagnosis and treatment.

Abstract
Posterior reversible encephalopathy syndrome (PRES), also known as reversible posterior leukoencephalopathy syndrome, is a neurological entity characterized by acute change in consciousness, visual impairment, headache, and seizures. It is associated with autoimmune disease, immunosuppressive agents, organ transplantation, acute glomerulonephritis, and sepsis. Typically, vasogenic edema is seen in the white matter of parieto-occipital lobes but can also involve atypical locations such as frontal lobes, thalamus, basal ganglia, and gray matter. While occurring extensively in adults, few cases, especially recurrent episodes, have been described in children. We report a case of recurrent PRES in a 17-year-old boy with end-stage renal disease on a peritoneal dialysis program who initially presented with hypertension and seizures. He emergently received intravenous antihypertensive medication with immediate and sustained improvement in his mental status. Information about recurrent PRES in children is limited because it is not commonly seen. We examine the clinical features of PRES and highlight important points for the diagnosis and management of this rare syndrome. This report demonstrates the importance of pediatricians to consider PRES in the differential diagnosis in children presenting with acute altered mental status. Blood pressure measurements, which are often overlooked in pediatric care, may assist in correctly diagnosing patients.

Peak blood pressure and prediction of posterior reversible encephalopathy syndrome in children. Pediatr Nephrol 2020; 35:1967-1975. [PMID: 32385528 PMCID: PMC8086820 DOI: 10.1007/s00467-020-04577-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Revised: 04/06/2020] [Accepted: 04/15/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Hypertension is a risk factor for posterior reversible encephalopathy syndrome (PRES), but the timing and severity of hypertension relative to PRES are unknown. The objective was to identify a clinically meaningful blood pressure (BP) threshold that predicts PRES development in high-risk children. METHODS We recorded peak systolic BP, diastolic BP, BP z-scores, and mean arterial pressure over the 14 days preceding clinical concern for PRES in 35 subjects who developed PRES, compared to 14 controls who had normal brain magnetic resonance imaging and similar underlying disease, renal function, and medications. We used multivariable logistic regression models adjusted for fluid overload and obesity to estimate the association of peak BP with PRES. We used receiver operating characteristic curves to determine which peak BP thresholds best predicted PRES and calculated the corresponding sensitivity, specificity, and positive and negative predictive values. RESULTS Peak systolic BP z-score was most strongly associated with PRES (OR 3.97, 95% CI 1.62-9.74), and peak systolic BP z-score ≥ 3.0 predicted PRES (area under the curve 0.95, 95% CI 0.88-1.0) with 91% sensitivity and 85% specificity, indicating 94% positive predictive value and 79% negative predictive value. CONCLUSIONS We demonstrated that peak systolic BP z-score ≥ 3.0 in the preceding 14 days predicted PRES development in cases compared with controls in children at high risk. Our study suggests that stage 2 hypertension, corresponding to a z-score ≥ 3.0, could help define hypertensive emergency in high-risk children and indicate when more aggressive treatment is warranted to prevent neurologic injury.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is a rare clinical syndrome that has been observed in different age groups, including pediatric patients. Identified triggers of PRES in both children and adults have included immunosuppressive and cytotoxic agents, organ transplantation, severe sepsis, blood transfusion, or evidence of human immunodeficiency virus-1 (HIV-1). Its clinical and radiological courses have been reported as mostly benign and reversible over days to weeks. Computed tomography (CT) scans are helpful in diagnosis, but magnetic resonance imaging (MRI) remains the gold standard. Unfortunately, because of the prohibitive costs of such medical equipment, diagnosis remains a challenge in developing countries. There is a dearth of information about pediatric PRES in resource-poor settings. This narrative aims to draw attention to the possible existence of PRES in children and to identify factors responsible for the difficulty in making the diagnosis. This review will hopefully increase awareness of PRES among pediatricians in order to make early diagnosis and institute appropriate management of this condition.

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
Visual disturbances are an uncommon pediatric chief complaint. Usually, after a complete ocular exam including visual acuity, most causes are benign and not life-threatening. Children with abnormal visual complaints who have underlying medical conditions, such as SLE or other autoimmune conditions, a recipient of a transplant, renal disease, and even eclampsia require closer scrutiny. We report a 10-year-old female with a history of systemic lupus erythematosus complicated by hypertension and cardiomyopathy secondary to lupus who presented to the emergency department with a history of vision loss and headache. Head computer tomography demonstrated findings of posterior reversible encephalopathy syndrome (PRES). PRES is a clinical disease associated with cranial radiological findings of heterogenous etiologies that is often reversible. Prompt recognition and treatment are important in preventing permanent damage, long term morbidity and even death.

Abstract
We present a case of posterior reversible encephalopathy syndrome (PRES) in a pediatric patient with Burkitt's lymphoma predominantly involving the bone marrow. F-FDG PET/CT scan obtained after the first cycle of chemotherapy, complicated by acute kidney injury, hypertension, tumor lysis syndrome, and lethargy with focal neurological symptoms, showed a favorable marrow and lymph node response but increased FDG uptake in the bilateral frontal and occipital cortical/subcortical regions. Brain MRI was consistent with PRES. The patient was managed with IV hydration and blood pressure control with symptom resolution. This case shows the F-FDG uptake pattern of PRES in postchemotherapy setting.

Abstract
Background Posterior reversible encephalopathy syndrome (PRES), also called the acute hypertensive encephalopathy and reversible posterior leukoencephalopathy syndrome (RPLS), is a neurotoxic syndrome of cerebral vasoregulation classically characterized by bilaterally symmetrical parieto-occipital edema. However, the imaging findings are variable and may occur in other locations such as the frontal lobes, thalami, basal ganglia and brainstem. Most commonly, PRES presents with hyperintense signals on T2 and FLAIR sequences. Restricted diffusion and hemorrhage are rare. This study presents the typical and atypical manifestations of PRES on 3T MR images. Material/Methods It is a retrospective study analyzing a radiology report database and MR images of 92 patients with a clinical and radiological diagnosis of PRES. The brain MRI images of these patients were evaluated. The regions involved and the signal intensity of the affected areas on T1, T2, FLAIR and DW sequences were recorded. The location of the abnormal signal intensity as well as the presence or absence of atypical features such as diffusion restriction and hemorrhage were also recorded. Results The most commonly affected region was the parieto-occipital lobes (100%), however, other atypical regions involved were the frontal lobes (30.4%), temporal lobes (8.69%), basal ganglia (22%), cerebellum(17.39%), brainstem(9%) and thalamus(4%). Some of the cases showed restricted diffusion (43%) and hemorrhage (9%). Conclusions The involvement of the parieto-occipital, frontal and temporal lobes is common in PRES. Occasionally, there may be an involvement of the basal ganglia, cerebellum and brainstem, with or without hemorrhage and restricted diffusion. Radiologists should be aware of the typical and atypical imaging manifestations of PRES in order to make an accurate diagnosis.

Abstract
In Sickle Cell Anemia (SCA) patient blood transfusions are an important part of treatment for stroke and its prevention. However, blood transfusions can also lead to complications such as Reversible Posterior Leukoencephalopathy Syndrome (RPLS). This brief report highlights two cases of SCA who developed such neurological complications after a blood transfusion. RLPS should be considered as the cause of neurologic finding in patients with SCA and hypertension following a blood transfusion.
