这是一个关于脑囊虫病影像诊断PPT课件,这个ppt包含了History,Diagnosis,epidemiology,classification,DDX,intracranial tuberculosis,IMAging,Metastatic encephaloma等内容。脑囊虫病是由寄生虫(猪绦虫为主)所传染的一种顽固性颅脑内疾病。该病约占囊虫病的80%以上。是由于口服了猪肉绦虫虫卵,发育成囊尾蚴,经消化道穿出肠壁进入肠系膜小静脉,再经体循环而到达脑膜、脑实质以及脑室内。可分为脑实质型、脑室型、脑膜型及混合型。患此病后脑组织及大脑中枢损伤严重,头疼、浑身无力、肢体运动障碍,最严重的是继发癫痫,视物不清,甚至失明等。更多内容,欢迎点击下载脑囊虫病影像诊断PPT课件哦。

Diagnosis
Cerebral Cysticercosis
epidemiology
most commonly in the whole body cysticercosis(80%)
most commonly in cerebral parasitic disease
more prevalent in the country
Pathogen: the cysticercus of armed tapeworm
classification
Parenchymal
Ventricular(the third or fourth)
Meningeal
Mixed
periodization
Subclinical stage
Active stage
Degeneration and death stage
Calcification stage
Mixed stage
Imaging
Active stage
small excentric spotty shadow of the mural cysticercus scolex
low signals on T1WI,high signals onT2WI

unremarkable peripheral edema
Degeneration and death stage
scolex disappearance
enlarged capsular cavity
remarkable peripheral edema
“white/black target sign”

“target sign”
ringlike or eggshell-like enhancement
Metastatic encephaloma
Primary leision(lung,braest,melanoma)
Multiple
Supratentorial(80%),subtentorial(20%)
Cortex-medullary junctions
Imaging
Isointensity on T1WI
Iso- or mildly hypointensity on T2WI
“small nodule and big edema” sign
necrosis and cystic degeneration
obvious nodular or ringlike enhancement
Brain abscess
Supratentorial(temporal lobe)
Pathogen:MRSA,streptococcus,pneumococcus
Periodization
acute encephalitis stage
suppuration stage
capsule formation stage
acute encephalitis stage
low signal on T1WI,high signal on T2WI
suppuration and capsule formation stage
the wall:
complete,smooth,thin,homogeneous
circular enhancement
“dark belt” sign
immunological examinations
CAg: activity of neurocysticercosis
IgG4:therapy effect
IHA/ELISA:supplementary indicator
treatment
Medical treatment : active stage
albendazole+praziquantel
Surgical operation : degeneration and death stage&granulomatous stage
cysticercosis enucleation
decompressive craniectomy
ventriculoperitoneal shunt
Conclusion
Making a correct diagnosis should be based on epidemiology, patient history, clinical manifestations, neuroimaging and laboratory examination,carring out a comprehensive analysis.
Some non-typical makes misdiagnosed easily, rechecking MRI and laboratory examination can help the differential diagnosis.

脑囊虫病PPT课件:这是一个关于脑囊虫病PPT课件,这个ppt包含了病理,感染途径,人群易感性,临床表现,实验室检查,临床诊断,根据病变的部位不同可分为,一般不做X线检查,CT检查,分型等内容。脑囊虫病又称囊尾蚴病,脑猪囊虫病。是猪绦虫幼虫寄生脑部所致。发病率约占囊虫病的80%。全国各地均有发生,主要流行于华北、东北、西北和华东北部各地区。囊尾蚴进入脑内形成囊泡,囊泡内含有液体和白色头节。虫体死亡,则由炎性细胞包裹,外层是富于血管的胶原纤维形成的肉芽肿。后期可由胶原纤维结缔组织修复变成瘢痕,死亡虫体发生钙化。更多内容,欢迎点击下载脑囊虫病PPT课件哦。
脑囊虫病PPT模板课件:这是一个关于脑囊虫病PPT模板课件,这个ppt包含了定义,流行病学特征,感染途径,病理,与症状有关的因素,临床表现,临床分型,辅助检查 ,免疫学等内容。猪囊尾蚴病是猪的链状带绦虫的幼虫(囊尾蚴)寄生于人体的各种组织而引起的疾病。脑囊虫病是指囊尾蚴寄生于人中枢神经系统。人脑是血液丰实的器官,也是囊虫寄生最常见的部位。囊尾蚴寄生于脑膜、大脑皮层、白质、脑室、脑干、脊髓蛛网膜下腔、脊髓等。更多内容,欢迎点击下载脑囊虫病PPT模板课件哦。
脑囊虫病PPT课件模板:这是一个关于脑囊虫病PPT课件模板,这个ppt包含了脑囊虫病-按部位分型,脑囊虫病-病理分期,脑囊虫病-临床,脑囊虫病-实验室,脑囊虫病-平片,脑囊虫病- CT等内容。脑囊虫是最常见的脑寄生虫病。不仅在东亚(我国主要在华北、东北地区)、南亚和拉美等发展中国家流行,近年随着旅游事业发展和移民增加,在欧美等发达国家的发病率也有增加趋势,故已引起各国对脑囊虫病的重视。中枢神经系统脑囊虫占囊虫病的80%,囊虫可寄居于大脑实质内、脑室内、蛛网膜下腔等部位,引起癫痫、颅内压增高等临床症状。脑囊虫分为:脑实质型、脑室型、蛛网膜下腔型和混合型四种。更多内容,欢迎点击下载脑囊虫病PPT课件模板哦。
