The posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity characterized by the association of clinical neurological signs (headache, confusion, vision changes, vomiting and seizures) and the typical changes in magnetic resonance imaging of the brain. Its pathogenesis is still poorly defined but seems to imply a vascular and endothelial dysfunction. It occurs more frequently in patients with hypertensive encephalopathy, eclampsia, renal failure and has also been associated with the use of immunosuppressive drugs. The authors present a case of PRES in a young woman with systemic lupus erythematosus with active and severe manifestations of the disease.

It is known that hemorrhagic stroke at the perinatal period are caused by specifics conditions like eclampsia as well as by the existing abnormal vessels. We treated a case of HELLP syndrome resulting in eclampsia with non-aneurysmal, convexity subarachnoid hemorrhage. A 34-year-old female, who had been pointed out to have a high level of urinal protein at the 37th week, was seen in the emergency department because of severe headache, vomiting and respiratory discomfort. Her systolic blood pressure was over 190mmHg, and caesarean section was selected. On the way to the operating room, she had a generalized convulsion with loss of consciousness. The delivery was carried out. The CT immediately after the caesarean section revealed faint and localized subarachnoid hemorrhage in the bilateral convexity areas. Additionally, the FLAIR image of MRI demonstrated increased intensity in the bilateral cerebellar hemispheres, basal ganglion and subcortical area, suggesting vasogenic edema. The patient had a good clinical course and the abnormal signal of MRI also recovered by treatment with oral iron and zinc. Here, we report a speculation for the mechanism of this case and precautions against stroke in the perinatal period.

Posterior reversible encephalopathy syndrome (PRES) is a serious clinico-neuroradiological maternal complication in pregnancy. Although it has various etiologies such as hypertensive encephalopathy, renal failure, autoimmune disorders, sepsis, multiple organ failure, and treatment with immunosuppressant or cytotoxic agents, pregnancy and postpartum complicated by hypertensive disorders more frequently lead to this condition. PRES is clinically characterized by headache, confusion, seizures, vomiting, and visual disturbances with radiographic vasogenic edema especially affecting symmetrical parietal and occipital lobes. The underlying pathophysiology is still a matter of debate. Prompt recognition and early intervention greatly improve the prognosis, so that obstetricians should be well aware of this rare entity. Timely imaging is of crucial importance especially in patients with an uncertain diagnosis for determining the appropriate treatment and preventing the possible development of neurologic deficits. In the present report, three cases of PRES are presented with clinical and radiological findings in pregnancies complicated by severe pre-eclampsia and eclampsia. The latest literature in the field is also carefully reviewed.

Posterior Reversible Encephalopathy Syndrome (PRES) is a neurological complication associated with several medical conditions and it has been described in clinical findings of seizures, headache, vomiting, altered mental status, and visual changes and focal neurologic deficit, in conjunction with radiological findings of primarily posterior cerebral white matter edema of both cerebral hemispheres. PRES can develop in a wide array situations including pregnancy and postpartum in patients with or without symptoms and signs of eclampsia. A prompt diagnosis of PRES by magnetic resonance imaging and an immediate antihypertensive and anticonvulsant therapy can help to prevent serious complications. The clinical case presented deals with a 35 year-old pregnant woman whose history of eclampsia was observed after a cesarean section.

Posterior reversible encephalopathy syndrome (PRES) is a rare but serious clinical-neuroradiological entity characterized by headache, vomiting, visual disturbances, altered mental status, seizures, and unconsciousness associated with the characteristic imaging findings including sub-cortical vasogenic edema at the bilateral parietal and occipital lobes. We describe a case of 28-year-old PRES patient secondary to delayed maternal postpartum eclampsia. This patient was not initially diagnosed with pre-eclampsia and PRES. The diagnosis was established after magnetic resonance imaging. After treatment this patient's PRES resolved. Early diagnosis and treatment are the keys to reverse PRES. A literature review for PRES is provided in this report.

Systemic lupus erythematosus (SLE) is associated with various neurologic or psychiatric abnormalities and Posterior Reversible Leuco Encephalopathy Syndrome (PRES) is very rare neurological manifestation in SLE. PRES is associated with various clinical manifestations, like, seizures, visual loss, headaches, vomiting altered mental status and rarely focal neurological deficits. Other predisposing condition associated with PRES is eclampsia, accelerated hypertension, uraemia, transplantation, autoimmune diseases and/or use of immunosuppressive drugs. It is important to recognise PRES since it is a potentially reversible. We describe an unusual case of PRES caused by uraemia during lupus flare up in a patient with biopsy proven class IV lupus nephritis who presented with features of asymmetrical quadriparesis which completely reversed after haemodialysis sessions and treating lupus flare up. In our case she presented with quadriparesis which is a rare presentation and hypertensive encephalopathy was not present.

Trombosis is seen in children with acute lymphoblastic leukemia during or after L-asparaginase treatment. Posterior reversible encephalopathy syndrome (PRES) is a complex syndrome characterized with sudden hypertension, headache, nausea, vomiting, alteration in the state of consciousness, vision defect and seizures. The cases related to this syndrome have been reportedly seen after eclampsia, organ transplantation, immunsuppressive treatments, autoimmune diseases and chemotherapy. Vasogenic edema occuring in the brain parencyhma constitues the basic pathophysiology. We present a case who developed seizures during treatment for B-cell acute lymphoblastic leukemia and diagnosed as posterior reversible encephalopathy.

A nulliparous pregnant woman in her mid-20s and in the 32nd week of gestation presented to the emergency department with severe headache and vomiting. She had an uneventful medical history; however, the physical examination upon hospital admission revealed a hypertensive emergency, papilledema, and 2+ dipstick proteinuria. Upon establishing the diagnosis of preeclampsia, aggressive therapy with corticosteroids, antihypertensive medication, and seizure prophylaxis was initiated. Hemodynamic stability was achieved within 24 hours and the patient remained in the observation unit located within the gynecology clinic. On the ninth day postadmission, however, her condition abruptly deteriorated and advanced to imminent eclampsia, accompanied by transient vision loss, altered mental status, and acute hypertensive crisis. After the patient underwent successful emergent delivery via caesarean section, a laboratory workup revealed hemolysis, elevated liver enzymes, and low platelet count, suggesting HELLP syndrome, a serious complication of eclampsia. This patient concurrently developed posterior reversible encephalopathy syndrome, which was confirmed by magnetic resonance imaging and acute respiratory distress syndrome (the latter presented with diffuse bilateral infiltrates on x-ray and developing pulmonary edema in the absence of cardiac etiology). Because of these life-threatening dynamics, the patient was transferred to the intensive care unit for further treatment. This case is a rare cascade of life-threatening complications that developed in a patient and required skillful multidisciplinary decision making and experienced management within an acute critical care setting. The final outcome of the treatment and intensive care was successful because both the patient and child survived and had no chronic or debilitating sequelae.

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological syndrome, usually reversible, characterized by vasogenic oedema in cerebral posterior regions in patients with autoimmune diseases, nephropathies, hypertensive crisis, eclampsia and exposure to cytotoxic drugs. The main symptoms are: headache, nausea, vomiting, seizures, visual disturbance and altered consciousness. Complications as cerebral hemorrhage and recurrences are rare. We describe a case of a 65 years old woman, affected by chronic kidney disease, recently exacerbated, diabetes and hypertension in treatment, who showed an heterogeneous clinical presentation with vomiting, headache, blurred vision and impaired consciousness during an episode of acute hypertension. After an adjustement of the antihypertensive treatment we observed a regression of symptoms in one week. FLAIR sequences on MRI showed cerebral bilateral vasogenic oedema in posterior regions, typical for PRES. This case was suggestive for PRES and a prompt adjustement of the antihypertensive treatment was critical for clinical recovery. Brain MRI was crucial for diagnosis. It is important for clinicians to recognize PRES as a possible complication of renal disease and hypertensive crisis.

Posterior reversible encephalopathy syndrome (PRES) or leukoencephalopathy syndrome was introduced into clinical practice in 1996 by Hinchey et al., to describe unique syndrome, clinically expressed during hypertensive and uremic encephalopathy, eclampsia, and immunosuppressive therapy. Hyperperfusion with resultant disruption of the blood-brain barrier results in vasogenic edema, but not infarction, most commonly in the parieto-occipital regions. The severity of this clinical symptom varies. For example, the visual disturbance can manifest as blurred vision, homonymous hemianopsia, or even cortical blindness. Patients may be mildly confused or agitated but can become comatose. Other symptoms less commonly seen include nausea, vomiting, seizures, and brainstem deficits. Chronic kidney disease (CKD) and acute kidney injury are both commonly present in patients with PRES. We are presenting a rare case of neurogenic bladder who developed PRES after augmentation cystoplasty due to underlying CKD.
