Posterior Reversible Encephalopathy Syndrome (PRES) is a cliniconeuroradiologic entity characterized by variable associations of nerve symptoms. The brain abnormalities tend to be symmetric and predominate in the posterior white matter. PRES can develop in colaboration with many circumstances including hypertensive encephalopathy, eclampsia, and usage of cytotoxic and immunosuppressant prescription drugs. Only handful of cases in the literature present an association between PRES and acute pancreatitis. We report a case of your 61yo female presenting PRES after Endoscopic Retrograde CholangioPancreatography related pancreatitis.


Intro: Posterior Inversible Encephalopathy Syndrome (PRES) is actually a clinic-neuroradiologic entity that was initially described by simply Hinchey ou al. in 1996

[1]. It is increasingly recognized and reported in case reviews but the actual incidence is not known

[2]. People of all ages appear susceptible an incident series suggest that it’s more widespread in women

[3, 4]. PRES is seen as a variable associations of seizure activity, consciousness impairment, severe headaches, visual malocclusions, and key neurological indicators

[5]. Typical findings in magnetic resonance imaging (MRI) happen to be symmetrical white colored matter edema in the detrás hemispheres, particularly the parieto-occipital areas

[6-9]. Both medical and radiological features are normally reversible once the cause can be removed. PRES occurs generally in the environment of hypertensive crisis, eclampsia, cytotoxic or perhaps immunosuppressant remedy and reniforme disease

[10-13]. Regardless the actual cause, the key abnormality is usually cerebral vasogenic edema

[14]. Just few situations in the books show an association between PRES and serious pancreatitis

[15-23]. Case report: A 61 years old caucasian girl, come to our attention through the emergency ward, complaining of abdominal soreness lasting intended for 5 days and nights. She known has been posted in the past to cholecystectomy and appendectomy, your woman denied good hypertension. The medical history was unremarkable. By blood samples, it was discovered a rise of total bilirubin (2. 1mg/dl), Gamma-Glutamyl-Transpeptidase (1105U/l) and Alkaline-Phosphatase (615U/l), inflammatory crawls, amylase and lipase serum levels had been in the normal range. An abdomen-US was performed: a mild dilatation of main fiel duct with out evidence of pebbles was discovered, a dilatation of intrahepatic biliary ducts was also present. As a result, the patient was admitted to the HPB unit of our clinic where the girl underwent ERCP (Endoscopic Retrograde CholangioPancreatography). This kind of examination revealed an swollen papilla, health and fitness a sub-stenosis of 1cm. Oddis sphinterotomy and cleaning of the inflammatory lesion was performed (the cytology was negative to get malignant tumour cell). A 10Fr biliary plastic stent was put. After a few hours from your procedure, the individual developed a post-ERCP pancreatitis, with an elevation of serum amylase (3262U/l) and lipase (3963U/l), WBC was 12, 6mg/dl. She also complained abdominal pain rebound, attentive to pain relief with NSAID. A period of time after the method the patient was at good standard condition with less abs pain. Inside the afternoon the person experienced the sudden presence of complete bilateral loss of sight. Vital parameters were typical except of mild hypertonie (160/80). With the Neurological exam the response of scholar to lumination was in one piece and no different focal symptoms where unveiled. A vascular and encephalic CT-scan was performed and showed zero evidences of organic conditions. After oculist examination, it was excluded whether opthalmological disease. Also ELEKTROENZEPHALOGRAFIE was usual. Than the sufferer was reviewed with encephalic contrast increased MRI that showed in both parietal and occipital lobes the existence of symmetrical areas of increased signal in the T2 FLAIR sequence (Figure 1). The radiological picture was compatible with PRES. An stomach TC-scan was performed and confirmed a mild inflammation of pancreatic head. The patient was treated conservatively with oral anti-hypertensive remedy and parenteral hydration. Following 36 several hours from the outset, her vision slightly return normal, but for three or more days the girl experienced visible hallucinations. Zwei staaten betreffend normal visus reached following 6 days. At the same time, serum amylase and lipase amounts decrease to normal range and the patient was discharged. A MRI was performed a couple weeks later and documented the full recovery with the brain signal intensity in the areas prior to affected (Fig. 2). Conversation: Posterior inversible Encephalopathy occurs in association with numerous medical condition which include hypertension, sepsis, shock, eclampsia, cytotoxic/immunosuppressive therapy, uremia, porphyria, connective muscle disease, alcoholic beverages, intoxication, hematological, renal or autoimmune disorders[10-13]. PRES evolves over a matter of several hours, with the most common presenting symptoms being seizures, consciousness disability, visual abnormalities and frustration. The intensity of clinical symptoms differs. Seizures and status epilepticus are common

[24]. Awareness impairment may well range in severity via confusion, somnolence, and listlessness to encephalopathy or coma[25]. The visual abnormalities can express as blurry vision, homonymous hemianopsia, cortical blindness, and visual hallucinations

[25]. Other symptoms less commonly seen incorporate nausea, nausea, and brainstem deficits[1]. Hypertension is often observed in PRES, but its level is certainly not correlated for the severity of PRES. Neuroimaging is essential for the diagnosis of posterior reversible encephalopathy syndrome. Standard findings will be bilateral and symmetric areas of white matter edema and predominating in the parietal and occipital bougie

[26]. The pathophysiology of PRES remains not clear, but it definitely seems to be related to disordered cerebral autoregulation and endothelial dysfunction t breakdown of blood head barrier witch may than trigger vasogenic cerebral edema[14]. In our case, affected person developed cortical blindness, with typical nerve findings of PRES in course of severe pancreatitis. She also developed a moderate hypertonie. The symptoms and MRI alteration regressed with the normalization of amylase and lipase levels. Only some cases of PRES in the setting of acute pancreatitis, with or without additional possible triggers for PRES, have been reported[15-23] (Table 1). The handful of reported cases of pancreatitis associated with PRES concern both equally genders and variable era (18-61 years). Various factors behind pancreatitis will be reported in colaboration with PRES (alcohol, traumatic pancratitis, nephrotic problem, porphyria, anabolic steroids and antiphospholipid syndrome). In acute pancreatitis, the serum levels of pro-inflammatory cytokines, lipase, and amylase are elevated which could have a determining rold in the progress extra-pancreatic issues

[27-28]. Experimental types in rodents suggested that during serious pancreatitis the pro-inflammatory cytokines, such as IL-6 and TNF, contribute to vasogenic brain edema through an alteration of the bloodstream brain barrier permeability.


Therefore it can be assumed that the pancreatitis alone can be a trigger, although unusual, of PRES. Obviously the info in the materials are few and further research are required to confirm these types of supposition.
