這是一個關(guān)于腦囊蟲病影像診斷PPT課件,這個ppt包含了History,Diagnosis,epidemiology,classification,DDX,intracranial tuberculosis,IMAging,Metastatic encephaloma等內(nèi)容。腦囊蟲病是由寄生蟲(豬絳蟲為主)所傳染的一種頑固性顱腦內(nèi)疾病。該病約占囊蟲病的80%以上。是由于口服了豬肉絳蟲蟲卵,發(fā)育成囊尾蚴,經(jīng)消化道穿出腸壁進(jìn)入腸系膜小靜脈,再經(jīng)體循環(huán)而到達(dá)腦膜、腦實質(zhì)以及腦室內(nèi)?煞譃槟X實質(zhì)型、腦室型、腦膜型及混合型;即瞬『竽X組織及大腦中樞損傷嚴(yán)重,頭疼、渾身無力、肢體運動障礙,最嚴(yán)重的是繼發(fā)癲癇,視物不清,甚至失明等。更多內(nèi)容,歡迎點擊下載腦囊蟲病影像診斷PPT課件哦。

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.

腦囊蟲病PPT課件:這是一個關(guān)于腦囊蟲病PPT課件,這個ppt包含了病理,感染途徑,人群易感性,臨床表現(xiàn),實驗室檢查,臨床診斷,根據(jù)病變的部位不同可分為,一般不做X線檢查,CT檢查,分型等內(nèi)容。腦囊蟲病又稱囊尾蚴病,腦豬囊蟲病。是豬絳蟲幼蟲寄生腦部所致。發(fā)病率約占囊蟲病的80%。全國各地均有發(fā)生,主要流行于華北、東北、西北和華東北部各地區(qū)。囊尾蚴進(jìn)入腦內(nèi)形成囊泡,囊泡內(nèi)含有液體和白色頭節(jié)。蟲體死亡,則由炎性細(xì)胞包裹,外層是富于血管的膠原纖維形成的肉芽腫。后期可由膠原纖維結(jié)締組織修復(fù)變成瘢痕,死亡蟲體發(fā)生鈣化。更多內(nèi)容,歡迎點擊下載腦囊蟲病PPT課件哦。
腦囊蟲病PPT模板課件:這是一個關(guān)于腦囊蟲病PPT模板課件,這個ppt包含了定義,流行病學(xué)特征,感染途徑,病理,與癥狀有關(guān)的因素,臨床表現(xiàn),臨床分型,輔助檢查 ,免疫學(xué)等內(nèi)容。豬囊尾蚴病是豬的鏈狀帶絳蟲的幼蟲(囊尾蚴)寄生于人體的各種組織而引起的疾病。腦囊蟲病是指囊尾蚴寄生于人中樞神經(jīng)系統(tǒng)。人腦是血液豐實的器官,也是囊蟲寄生最常見的部位。囊尾蚴寄生于腦膜、大腦皮層、白質(zhì)、腦室、腦干、脊髓蛛網(wǎng)膜下腔、脊髓等。更多內(nèi)容,歡迎點擊下載腦囊蟲病PPT模板課件哦。
腦囊蟲病PPT課件模板:這是一個關(guān)于腦囊蟲病PPT課件模板,這個ppt包含了腦囊蟲。床课环中,腦囊蟲。±矸制,腦囊蟲。R床,腦囊蟲。瓕嶒炇,腦囊蟲病-平片,腦囊蟲病- CT等內(nèi)容。腦囊蟲是最常見的腦寄生蟲病。不僅在東亞(我國主要在華北、東北地區(qū))、南亞和拉美等發(fā)展中國家流行,近年隨著旅游事業(yè)發(fā)展和移民增加,在歐美等發(fā)達(dá)國家的發(fā)病率也有增加趨勢,故已引起各國對腦囊蟲病的重視。中樞神經(jīng)系統(tǒng)腦囊蟲占囊蟲病的80%,囊蟲可寄居于大腦實質(zhì)內(nèi)、腦室內(nèi)、蛛網(wǎng)膜下腔等部位,引起癲癇、顱內(nèi)壓增高等臨床癥狀。腦囊蟲分為:腦實質(zhì)型、腦室型、蛛網(wǎng)膜下腔型和混合型四種。更多內(nèi)容,歡迎點擊下載腦囊蟲病PPT課件模板哦。
