Posterior reversible encephalopathy syndrome (PRES) and reversible cerebral vasoconstriction syndrome (RCVS) are relatively uncommon neurological disorders. These two independent syndromes can be concurrent as a part of a continuum process; however, the specific mechanism is not well known. Although the relationship between RCVS and PRES is currently unclear, they could share a common pathophysiology. This case report aimed to determine the pathophysiology underlying the co-occurrence of PRES and RCVS in a patient with an acute exacerbation of chronic obstructive pulmonary disease.

Takayasu arteritis (TA) is a chronic inflammatory disease of unknown etiology that affects mainly the aorta, main aortic branches, and pulmonary arteries. Diverse neurological manifestations of TA have rarely been reported in children. Posterior reversible encephalopathy syndrome (PRES) is a neuroradiological condition that presents with headache, seizure, visual disturbances, and characteristic lesions on imaging. Inflammatory condition and severe hypertension in TA can cause PRES. We report of a 5-year-old girl with presumed TA who presented with PRES and chronic total occlusion in the renal artery. The findings on magnetic resonance imaging suggested PRES. Left nephrectomy was performed for total occlusion of the left renal artery, and the confirmatory diagnosis of TA was based on the pathologic findings of the renal artery.

Although posterior reversible encephalopathy syndrome (PRES) is induced by various causes, a few cases have occurred after severe anemia correction. In this case report, a 45-year-old female patient visited emergency department with a chief complaint of dizziness due to severe anemia related to hypermenorrhea caused by uterine myoma. Before her operation, she had an abrupt headache and seizure during anemia correction with transfusion and injection of gonadotropin-releasing hormone agonist. Immediately after the operation, she experienced visual disturbances, followed by limb weakness and tonic-clonic movements. Magnetic resonance imaging showed alterations in parietal and occipital lobes suggesting cerebrovascular edema with hypoperfusion. Here, we presented and discussed the clinical and radiologic features of PRES related to anemia correction.

Although most cases of posterior reversible encephalopathy syndrome (PRES) are reversible, irreversible lesions as a form of hemorrhage or infarction have been described. PRES as a complication of systemic lupus erythematosus (PRES-SLE) is associated with hypertension or use of immunosuppressive agents. We present a case of recurrent atypical PRES-SLE, which showed restricted diffusion in the first manifestation of SLE, resulted in parenchymal hemorrhagic transformations in the recurrent episode.

We report a unique case of intestinal duplication detected on posterior reversible encephalopathy syndrome (PRES) in a 13-year-old girl. She was admitted to the pediatric Emergency Department because of generalized seizures. Radiological assessment revealed a large, well-defined, thick-walled cystic lesion in the mid abdomen, suggestive of duplication cyst associated to a PRES. Exploration confirmed the diagnosis of ileal duplication cyst, and the mass was resected. The postoperative course was uneventful. Both hypertension and neurological dysfunction resolved after the mass resection. A follow-up brain magnetic resonance imaging was performed 9 months later and showed complete resolution of the cerebellar changes. Although extrinsic compression of the retroperitoneal structures has not been reported in the literature as a complication of duplication cyst, we strongly believe that this is the most logical and plausible hypothesis that would explain the pathogenesis of PRES in our patient.

Seizure is a foreseeable risk in patients with brain lesion. However, seizure during treating non-brain lesion is not a familiar situation to neurosurgeon. Posterior reversible encephalopathy syndrome (PRES) is a relatively common situation after systemic chemotherapy. The aim of this study is to make neurosurgeons aware of this potential medical problem. A 52-year-old woman with advanced gastric cancer, presented with low back pain due to spinal metastasis at the 4th lumbar vertebra. Ten cycles of chemotherapy with FOLFOX (5-Fluoruracil/Oxaliplatin) had been completed 23 days ago. Two days before the planned operation, a generalized tonic clonic seizure occurred. She did not have a history of hypertension or seizure. The seizure was stopped with lorazepam 4mg. The brain magnetic resonance (MR) imaging showed high signal changes in both parieto-occipital lobes on the T2-weighted images, and these were partially enhanced, suggesting PRES. The surgery was preceded by treatment with an antiepileptic drug. The MR images, taken 1.5 months after the seizure, showed that the lesion was no longer present. At 3 month follow-up, no additional seizure attack occurred without any seizure medication. The possibility of a seizure attack should be considered if the patient has a history of chemotherapy.

Posterior reversible encephalopathy syndrome (PRES) is a rare condition manifested by inflammation in certain areas of the brain. Rhabdomyolysis with acute kidney injury (AKI) complicated by PRES is rarely reported. A 26-year-old female presented with neurological symptoms, high blood pressure, and AKI. Her symptoms improved with blood pressure control, anticonvulsant drug medications, and renal replacement therapy. This case demonstrates that PRES should be considered in the differential diagnosis of patients who have rhabdomyolysis with AKI accompanied by neurological symptoms, including headaches and convulsions.

Reversible posterior leukoencephalopathy syndrome (RPLS) is an acute encephalopathy, usually characterized by seizures, visual disorder, mental change and reversible posterior white and gray matter lesions on brain magnetic resonance imaging (MRI). Conditions commonly associated with RPLS include acute renal failure, eclampsia, hypertension, immunosuppresion state, and use of intravenous immunoglobulin or chemotherapy, and additional contributing factors. We report the case of RPLS associated with cyclosporine use in lupus nephritis. In this case, it was not clearly elucidated which was main cause of RPLS. We could think RPLS developed maybe due to combined effect of cyclosporine and lupus nephritis.

The posterior reversible encephalopathy syndrome(PRES) is characterized clinically by a combination of acute or subacute confusion, lethargy, visual disturbance, and seizures. PRES has been described in various clinical settings, including severe hypertension, chemotherapy, eclampsia, and seizure. We report a case of a 7-year-old girl who had taken cyclosporine for steroid resistant nephrotic syndrome. Twenty one days after the cyclosporine therapy, she was admitted due to generalized tonic clonic seizure and headache. Her blood pressure was 170/90 mmHg. Magnetic resonance(MR) imaging showed necrotic/cystic lesions involving the bilateral parieto-occipital region. After discontinuation of cyclosporine, and control of blood pressure, she had no more seizure and headache. The follow-up MR examination which was performed 6 months later showed the decreased extent of the lesion.
