Objective To report a case presented with atypical clinical and radiological appearance in the early stage and finally pathologically confirmed as chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids ( CLIPPERS) , aiming to improve the understanding of the disorder. Methods The clinical, imaging, laboratory and pathological features as well as treatment and prognosis of a pathologically confirmed CLIPPERS patient with repeated relapsing-remitting course and stepwise progression in nine years were retrospectively analyzed. Results There were five relapsing-remitting processes in total clinical course of nine years. The clinical and radiological appearance was atypical in the early stage. At the first attack, the patient presented with fever, headache, altered consciousness and epileptic seizure. In the following courses, the patient presented with ataxia, blurred vision and limb weakness. Brain MRI (2006-2009) showed multiple abnormal signals including supratentorial white matter, pons and cerebellum with patchy gadolinium enhancement. Treatment with steroids resulted in a favorable clinical and radiological improvement. The symptoms of this attack included limb weakness, blurred vision, dysdipsia and dysarthria. Physical examination showed cognitive dysfunction, multiple cranial nerves injuries and bilateral pyramidal signs. Brain MRI showed multiple abnormal signals involved pons and cerebellum predominantly as well as supratentorial white matter with punctate gadolinium enhancement peppering the pons and cerebellum. A characteristic predominantly T lymphocytic perivascular infiltration was seen on brain biopsy. Both the imaging and histological findings were consistent with the CLIPPERS features. High-dose steroids treatment was given and obvious clinical and radiological improvements were observed. After discharge, steroids were reduced slowly combined with the use of immunosuppressant to avoid relapse of the disorder. Conclusions There is heterogeneity in clinical manifestations of CLIPPERS with repeated relapsing-remitting course and imaging presentations are sometimes atypical in the early stage, which leads to the misdiagonsis and missed diagnosis. Distinctive pathology is the “gold standard” for definite diagnosis. The nosological position of CLIPPERS is still unclear. Repeated relapse-remitting leads to secondary cerebral atrophy and degeneration, with the risk of progressing to primary central nervous system lymphoma. Early and vigorous steroids treatment with continuing maintenance immunotherapy results in the decreased relapse and best long-term prognosis. The neurologist should strengthen the understanding of CLIPPERS for early correct diagnosis and treatment aiming to reduce the functional disability.

Neurosurgical emergencies including intracranial hemorrhage and head trauma have high mortality and morbidity rates and meanwhile are often accompanied with coagulation disorders. On one hand, coagulation disorder follows traumatic brain injury;on the other hand, the increasing use of anticoagulant and antiplatelet treatment for cardiovascular diseases increases the risk of death among patients with brain trauma or bleeding. Once the intracranial pressure increases, such patients need emergency surgical intervention, but coagulation disorder is a relative contraindication. This article reviews the pathogenesis and treatment of coagulation disorders in patients with neurosurgical emergency. It also analyzes clinical monitoring indices for such patients and their variations and summarizes the strategies and measures of perioperative management.

Objective To explore the feasibility of 256-slice whole-brain CT perfusion (CTP) in evaluate graft reperfusion after surgical revascularization and hemodynamic alterations before and after surgery in Moyamoya disease. Methods Twenty-five cases with Moyamoya disease were scanned on a 256-slice CT.CTP was performed pre- and post- surgical revascularization. The wolumetric CT angiographic ( CTA ) images were generated from volumetric data acquired at the arterial phase of CTP. CBF, CBV, TTP and MTT were measured in functional maps at the operated side within middle cerebral artery perfusion areas and contralateral mirroring areas. Relative CBF( rCBF), relative CBV (rCBV), relative TTP (rTTP), relative MTT (rMTT) were also obtained. Differences in perfusion CT values pre- and post operation were assessed with the paired t test or matched-pairs signed-ranks test. Data with normal distribution was present as : (x-)± s,while those with the non-normal distribution were present as M ( P25-P75 ). Results All the direct graft patencies were displayed on volumetric CTA. No significant differences were found between volumetric CTA and conventional CTA. Postoperative CBF, rCBF and rCBV values of the operated side [ 72. 86 (55.54-112. 19) ml · 100 g-1 · min-1 , 1. 31 ( 1.05-1.73), 1.45 ±0. 62] were significantly higher than those before operation [46.72(28.57-57.67) ml · 100 g-1 · min-1, 0.53(0.33-0.82), 1.01 ±0.36](Z=- 2.72, - 2. 98, t = - 2. 85, P ＜ 0. 05 ). Postoperative MTT, TTP and rTTP values of the operated side [ (3.98 ± 2. 36 ) s, ( 17.56 ± 4. 38 ) s, 1.01 ± 0. 09 ] were significantly lower than those before operation [(5.43±2.07) s,(19.40±3.87) s,1.14±0.28] (t=2.41,2.17,2.17, respectively, P＜0.05).However, no significant differences were detected for changes of CBV and rMTT after revascularization ( P ＞0. 05). Conclusion 256-slice CT has the potential value for the non-invasive assessment of both the graft patency and cerebral hemodynamics changes in moyamoya disease after surgery with administration of one contrast medium bolus in a single examination.

Objective To investigate the expression and clinical significance of MUC1,MUC2,MUC4 and MUC5AC in pancreatic ductal adenocarcinoma(PDA).Methods To analyze the expression profiles of MUC1,MUC2,MUC4 and MUC5AC in PDA(n=26),chronic pancreatitis(CP,n=4),normal pancreas(n=16)and intraductal papillary-mucinous neoplasm(IPMN)(n=2),solid-pseudo-papillary tumor of pancreas(SPT)(n=4),serous cystic neoplasm(SCN)(n=1)using immunohistochemistry.Results Positive staining with MUC1 Was exclusively found in normal pancreas and CP tissues(100%);the expression of MUC1,MUC4 and MUCSAC in PDA was 100%,88.5%(23/26)and 76.9%(20/26)in PDA tissue;MUC2 and MUC5AC were expressed in 2 samples of IPMN;none of the four mucins were expressed in Sfrr and SCN.There was no association between the expression of MUC4,MUC5AC and the clinicopathologic parameters in PDA(P＞0.05).Conclusions Multiple mucins were expressed in PDA.Measurement of the mucin profile including all 4 mueins(MUC1,MUC2,MUC4,and MUC5AC)may be helpful in the diagnosis and differential diagnosis of PDA.

Objective Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described brainstem-predominant inflammatory disorder responsive to steroids with characteristic magnetic resonance imaging(MRI) feature.There was no case report in China.The aim of this study was to characterize the clinical and imaging patterns of CLIPPERS for early diagnosis and treatment.Method Clinical and imaging data and therapeutic methods and following up after treatment of 1 patient diagnosed CLIPPERS were reviewed retrospectively.Results The patient presented with subacute weakness of the lower extremities,gait ataxia and facial numbness.Cerebellar ataxia and pyramidal signs were the main positive signs on neurological examinations.Brain MRI showed punctate gadolinium enhancement peppering the pons and cerebellar.Treatment with steroids led to rapid clinical improvement and marked resolution of MRI lesions which accorded with characteristics of CLIPPERS.Conclusions There are no characteristic clinical manifestations of CLIPPERS.Punctate gadolinium enhancement peppering the pons is the distinct magnetic resonance imaging feature which may suggest the clinical diagnosis of CLIPPERS.Early treatment with steroids can improve the prognosis.
