This is a case of a 56-year-old lady with recent autologous peripheral stem cell transplantation for multiple myeloma. She was presented with a 48 h history of worsening headache, drowsiness, nausea/vomiting and some peripheral neurological symptoms. She developed status epilepticus, was intubated and transferred to intensive care unit. After full investigation with a CT head, CT cerebral angiogram, MRI brain and cerebral angiogram, she was diagnosed with posterior reversible encephalopathy syndrome (PRES) with the help of expert opinion, based on the clinical and radiological evidence. The MRI showed bilateral occipital signal changes suggestive of PRES. She was managed with nimodipine, phenytoin and clonazepam with good effect. Eventually extubated, she made good progress on the ward with no further seizure episodes. Functionally she did not appear to have any evidence of residual damage from the PRES. This case discusses PRES on a background of a haematological malignancy and its clinical features.

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiologic entity with typical symptoms including headache, seizures, visual disturbance, altered mental status, vomiting, nausea and focal neurologic signs. In this article, we report recurrent and atypical PRES in a child with hypertension due to end-stage renal disease (ESRD) who was on a peritoneal dialysis program for 6 months. After the second hypertension attack, PRES findings did not recover and persisted as encephalomalacia. As far as we know, this case is the first child with ESRD who developed encephalomalacia after recurrent episodes of PRES. When a patient with a history of PRES presented with new clinical and neuroradiological findings, recurrent PRES should be considered.

Posterior reversible encephalopathy syndrome (PRES) is a temporary condition that is diagnosed clinically, neurologically, and radiologically. Its symptoms vary, and nonspecific headaches, confusion, impairment of consciousness, nausea, vomiting, and visual impairment may occur. Acute hypertension often accompanies these symptoms. Patients can also suffer from convulsions, cortical visual impairment, and coma. Diagnosis can be difficult due to focal neurologic signs. Nevertheless, knowing the clinical risk factors can lead to the right diagnosis. It has been reported that this condition may also occur during organ transplantation, immunosuppressive treatment, and autoimmune diseases and chemotherapy, and also patients with eclampsia. In this paper, a 21-year-old, 31-week pregnant woman, who had been diagnosed with PRES and thanks to early diagnosis and treatment had fully recovered and discharged from the intensive care unit, is presented, and the relevant literature is discussed.

We experienced a patient with cat-scratch disease (CSD) who developed encephalopathy. The subject was a 34-year-old female who had been aware of a low-grade fever and swollen inguinal lymph nodes for 1 month. The subject's consciousness became impaired after a headache developed, accompanied by fever, nausea, and vomiting, and she subsequently sought medical consultation. No major abnormalities were observed in the cerebrospinal fluid and cranial magnetic resonance imaging (MRI) was normal. However, necrotizing lymphadenitis was observed on contrast enhanced computed tomography (CT) of the pelvis and granulomatous changes were observed in a surgical lymph node biopsy. As the subject lived with a pet cat, PCR testing for Bartonella henselae (the CSD pathogen) was performed using a tissue biopsy. This was positive and the subject was diagnosed with CSD encephalopathy. There are very few domestic reports of CSD encephalopathy and care must be taken not to overlook this disease.

Posterior reversible encephalopathy syndrome (PRES) is characterized by headache, nausea, vomiting, seizures and visual disturbances. PRES has been usually associated with hypertension, chronic renal disease, malignancy and chemotherapeutic agents. We report the association of PRES with Autoimmune lymphoproliferative syndrome, which to our best knowledge has not been reported before.

The standard treatment for peptic ulcer associated with Helicobacter pylori is a combination of omeprazole, amoxicillin and clarithromycin, which renders the bacterium undetectable in about 70% of cases. A fixed-dose combination of bismuth subcitrate potassium + metronidazole + tetracycline has been authorised in some European countries for use in this setting, combined with high-dose omeprazole. In a European trial with 440 patients, the 4-drug combination of omeprazole + bismuth subcitrate + metronidazole + tetracycline was significantly more active than the standard 3-drug regimen in terms of H. pylori eradication, as measured with the urea breath test (79.8% with bismuth, 55.4% without bismuth). In a North American trial with 275 patients the success rate was similar with the two treatments, again based on the urea breath test. There are no comparative trials of the 4-drug regimen in patients in whom standard treatment has failed. The main adverse effects of the 4-drug regimen observed in clinical trials were black stools, nausea, headache and dizziness. However, the trials were too small to detect infrequent but serious adverse effects such as bismuth encephalopathy. Safety during pregnancy is not known. Some patients included in clinical trials had detectable plasma bismuth concentrations. Omeprazole increases the absorption of bismuth subcitrate potassium. In practice, the 4-drug regimen combining omeprazole + bismuth subcitrate potassium + metronidazole + tetracycline is probably more effective than standard 3-drug therapy against H. pylori, at least in Europe, but this combination should be avoided due to uncertainties on the possible neurotoxicity of bismuth. Other antibiotic combinations are preferable, and there are too many questions surrounding the adverse effects of this combination for it to replace the standard 3-drug regimen in France.

Neuromyelitis optica (NMO) is an inflammatory demyelinating disorder that predominantly affects the optic nerve and spinal cord; however, symptomatic brain involvement is not rare and is sometimes an initial manifestation in NMO. In this study, we investigated the characteristic features of patients with NMO with symptomatic brain involvement as the initial manifestation of disease (NMO(brain)) compared with patients with NMO who presented initially with optic neuritis or myelitis (NMO(ON/myelitis)). We retrospectively reviewed 27 consecutive Korean patients with NMO with aquaporin-4 antibodies. Patients with NMO(brain) (n=9) initially presented with intractable hiccup/nausea/vomiting and/or encephalopathy at a younger age than the patients with NMO(ON/myelitis) (n=18) (p<0.01). During the disease course, the patients with NMO(brain) continued to show more frequent symptomatic involvement of the brain than the 18 patients with NMO(ON/myelitis) (p<0.05). At the final visit, the mean age was also significantly lower in patients with NMO(brain) than in patients with NMO(ON/myelitis) (p<0.01); however, the Expanded Disability Status Scale scores, used to evaluate disease progression, were not different between the two groups. Our study suggests that patients with NMO who present initially with symptomatic brain involvement may have earlier disease onset and become disabled at a younger age compared to patients with typical NMO. Additional large scale prospective studies are warranted.

A 29-year-old woman complained of headache and nausea several hours after delivery, followed by mild disturbance of consciousness. Physical examination revealed hypertension, systemic edema, nystagmus, dysarthria, and cerebellar ataxia. Computed tomography showed low attenuation areas in the cerebellum, and MR imaging revealed vasogenic edema in the cerebellum. MR angiography and MR venography demonstrated no significant abnormalities. We diagnosed a cerebellar variant of posterior reversible encephalopathy syndrome(PRES), and treated the patient immediately with antihypertensive drug and diuretic. The symptoms dramatically improved and MR imaging ten days after admission revealed disappearance of the vasogenic edema in the cerebellum. She was discharged without any sequelae. Though a cerebellar variant of PRES is very rare, rapid diagnosis and treatment is important for good prognosis when the disease is encountered.

A 71-year-old woman with myelofibrosis on chemotherapy experienced an acute illness with nausea, vomiting, and diarrhea. Two weeks later, she developed an acute confusional state characterized by disorientation and fluctuating alertness with normal speech and language. Her neurologic examination demonstrated an upper motor neuron pattern of right hemiparesis. She reported double vision though ophthalmoparesis was not appreciated. Her gait was normal. While hospitalized, she developed generalized tonic-clonic seizures. Brain MRI revealed a small area of restricted diffusion of the left precentral gyrus (figure). She was diagnosed with a stroke with secondary seizures; however, as the confusional state resolved, she developed profound retrograde and anterograde amnesia. Review of the brain MRI showed high T2 signal in the medial thalamus and contrast enhancement of the mamillary bodies; a diagnosis of Wernicke-Korsakoff syndrome was entertained and she was started on thiamine replacement. The encephalopathy and hemiparesis resolved though she remains severely amnestic.

Posterior reversible encephalopathy syndrome is a clinicoradiologic syndrome characterized by seizure, headache, nausea, vomiting, altered mental status, visual disturbance, or visual loss, together with radiologic findings. Herein we reported a patient who was a 27-year-old foreign workman brought to the emergency ward with blurred vision in both eyes, neck pain, somnolence, and altered mental status. He had no known medical or family history. On his physical examination, his blood pressure was 190/100 mmHg and visual acuity of both eyes was decreased (visual acuity = 20/40 for both eyes). Although blood pressure was controlled by intravenous labetalol bolus, his symptoms did not improve. The result of his brain computed tomographic scan was normal, but in the brain magnetic resonance imaging, there were hyperintensities in the occipital lobe and right cerebellar hemisphere, suggesting posterior reversible encephalopathy syndrome. The findings from a complete blood count, biochemical testing, and renal, pelvic and abdominal ultrasound and also the calculated glomerular filtration rate values revealed that all were in favor of chronic kidney disease (hemoglobin level, 10.3 mg/dL; blood urea nitrogen, 90 mg/dL; Cr, 6.8 mg/dL; potassium, 5 mEq/L; sodium, 140 mEq/L; Cockcroft-Gault glomerular filtration rate, 15; weight, 65 kg). The hemodialysis was performed by which the sign and symptoms and radiologic findings resolved within 24 hours. Although PRES is described to be in association with many medical conditions, as mentioned in many available articles, we came to a conclusion that PRES could be the first presentation of a condition such as chronic kidney disease in our case.
