Objective To analyze clinical characteristics of migraine complicated with cerebral edema.Methods We first time reported a case of familiar hemiplegic migraine complicated with diffuse cerebral edema in China,another 19 cases of migraine complicated with cerebral edema were reported in literature.The clinical characteristics of these 20 cases were analyzed.Results In 20 cases,the male:female ratio was 1.2∶ 1,the mean age of onset was (16.0 ± 10.2) years.All 20 cases were complicated with cerebral edema,among whom 8 (40％) were familiar hemiplegic migraine,8 (40％) were sporadic hemiplegic migraine,4 (20％) were migraine with aura.Common neurological symptoms and signs included paralysis (75％),aphasia (65％),disturbance of consciousness (60％),disordered vision (40％),Paresthesia (35％).Eleven cases (55％) had permanent neurological deficit.Conclusions The clinical manifestations of migraine with cerebral edema are complicated,the neurological disturbance is severe and usually has a long duration.The early diagnosis and treatment is beneficial,and preventive treatment in intermittent period is recommended.

Six patients with Neuro-Behcet disease (NBD) were admitted in Beijing Hospital from 2000 to 2014,during the same period 344 NBD cases were reported in the literature.The clinical data of 350 Chinese NBD patients,including the symptoms,signs,laboratory tests,imaging,treatment and prognosis were retrospectively analyzed.The average onset age was 36.7 years old.The average interval time from Behcet disease (BD) to NBD was 5.6 years.NBD often occurred in male,the male/female ratio was 1.94:1.The most common manifestations were oral ulcer 94.9％ (277/292),followed by genital ulcer 69.1％ (215/311) and fever 42.1％ (131/311).The most common symptoms in neurology were limb weakness (36.9％,129/350),headache (34.0％,119/350) and sensory disturbance (21.1％,74/350),followed by bulbar symptoms (11.4％,40/350),pyramidal sign was most often (27.1％,95/350).The central neurology system (CNS) was the major target of NBD,parenchymal CNS was affected most (88.0％,308/350),non-parenchymal CNS was affected less (5.7％,20/350),peripheral neurology system (PNS) was rarely affected (6.9％,24/350).Steroids were the first-line drug for NBD,if it failed,immunosuppressive agents or biologic agents could be used.The most NBD patients had single episodes,32.0％ (49/153) had relapses with remission,7.7％ (27/350) had adverse prognosis.Analysis showed that NBD should be paid more attention.
