Pakali pano ndikudziwa, palibe chinthu ngati ubongo wabwino. Izi zati, nthawi zambiri meningioma imakhala ngati chotupa cha ubongo monga momwe mungapezere. Ndipotu, m'njira zina, sichiwerengera ngati chotupa cha ubongo.
Kodi Meningioma Ndi Chiyani?
Ngakhale kuti meningiomas kaŵirikaŵiri imakhala ngati chotupa chachikulu cha ubongo , ndimagwiritsa ntchito mawu omwe ali pamwambawa chifukwa chakuti kwenikweni meningioma si chotupa cha minofu ya ubongo konse.
Mmalo mwake, meningioma imakula kuchokera ku meninges, minofu yotetezera yozungulira ubongo. Makamaka, meningiomas kawirikawiri imachokera ku arachnoid mater .
Manyowa amatsatira makutu akuluakulu a ubongo. Mwachitsanzo, meninges akudutsa pakatikati pa ubongo komwe mbali ya kumanzere ndi yolondola imasiyanitsidwa, komanso kukulunga pamunsi pa chigaza ndi mitsempha ya optic. Zizindikiro ndi chithandizo cha meningioma zimadalira pa malo otupa.
Kodi Ambiri Amadziwika Bwanji Kawirikawiri?
Pamene kuphunzira kwa anthu opitirira 2000 pa autopsy kwanena kuti pafupifupi 1 peresenti ya anthu akhoza kukhala ndi meningioma, iwo sali omwe amapezeka kuti ali amoyo. Ziphuphu zikhoza kukula pang'onopang'ono, nthawi zina nkomwe.
Malinga ndi Central Brain Tumor Registry ku United States (CBTRUS), kuchuluka kwa meningioma ku United States kuli anthu pafupifupi 170,000. Malingana ndi ziŵerengero zimenezi, meningiomas ndi ena mwa mavenda ambiri a ubongo, omwe amawerengera pafupifupi gawo limodzi mwa magawo atatu alionse.
Ngati meningiomas amachititsa mavuto, nthawi zambiri amawachitira opaleshoni mosavuta. Izi zikuti, meningiomas nthawi zina ingakhale yoopsa kapena ngakhale kuopseza moyo. Kusiyanasiyana kuli mu mtundu ndi malo a meningioma, komanso maonekedwe apadera a anthu pawokha.
Ngozi
Zowopsa kwa meningioma sizingathandizidwe.
Mwachitsanzo, meningiomas ndi ochepa kawiri kawirikawiri mwa amayi poyerekeza ndi amuna. Chiwerengero cha meningiomas chimakula ndi msinkhu. Zimakhala zosayembekezereka mwa ana koma mwinamwake ndi mtundu wambiri wa ubongo wa ubongo umene umapezeka mwa anthu opitirira zaka 85.
Palinso zifukwa zomwe zimayambitsa matenda a meningoma. Chodziwika kwambiri ndi mtundu wa neurofibromatosis mtundu wachiwiri, umene umapangitsa mwayi wa wina kupeza mazenera ambiri. Matendawa amachokera ku nthenda ya NF2 , yomwe imathandiza kwambiri kuteteza zilonda zam'mimba. Zina zamtundu zomwe zimagwiritsidwa ntchito mwa meningioma ndi DAL1, AKT1, ndi TRAF7.
Mafunde ndi omwe amawopsa kwambiri chifukwa cha meningioma. Izi zimaphunziridwa bwino kwambiri pamene ubongo wakhala utawopsyeza pochiza khansa yosiyana. Popeza zingakhale nthawi yayitali pakati pa nthawi ya ma radiation ndi kupezeka kwa meningioma, chiopsezo chili choposa ana. Mwachitsanzo, pofufuza anthu 49 omwe anali ndi ubongo wa khansa, anadwala 11, anali ndi meningiomas pambuyo pa zaka 25. Mafilimu ndi njira zamankhwala monga zama X-rays zamkati zimakhala zochepa kwambiri, ngakhale kuti kafukufuku wasonyeza kugwirizana pakati pa kugwiritsa ntchito X-rayoni komanso kukula kwa meningioma.
Zina zomwe zingakhale zoopsa za meningioma zakhala zikuphunziridwa ndi zotsatira zotsutsana, kuphatikizapo kunenepa kwambiri, kutulutsa mahomoni, ndi kupsinjika mutu.
Kodi N'chiyani Chimapangitsa Meningioma Kwambiri?
Ngakhale kuti meningiomas ambiri ndi owopsa kwambiri kuti mwina angapewe kuzindikira, angakhale ovuta kwambiri. Bungwe la World Health Organization lagawira meningiomas mu sukulu zitatu zosiyana ndi maonekedwe awo pa microscope. Pamene apitirira msinkhu, ndiye meningoma yoopsa kwambiri.
- WHO Ophunzira 1: Kalasi I meningiomas ndi yosavuta. Ngakhale kuti amafunikanso opaleshoni kuti asamapangidwe kazinthu zofunikira za ubongo, nthawi zambiri palibe chofunikira kuposa kufufuza nthawi zamakono kuti zisawonongeke kwambiri.
- WHO Ophunzira 2: Meningiomas awa ali ndi zizindikiro zochuluka za maselo ogwira ntchito. Chenjezo lofunika kwambiri liyenera kutengedwa ndi izi zotupa. Zigawozo zimaphatikizapo chordoid, selo yoyera, ndi meningomas atypical.
- WHO Maphunziro achitatu: Ziphuphuzi zili ndi zizindikiro zingapo zogwirizanitsa maselo. Chotupacho chingakhale chilowerera mkati mwa ubongo kapena kusonyeza mbali za kufa kwa maselo. Mankhwalawa amaphatikizapo papillary, rhabdoid ndi amaplastic meningiomas. Awiri okha kapena atatu peresenti ya meningiomas onse ndi Gawo 3.
Odwala omwe ali ndi masewera apamwamba a meningiomas amatha kukhala ndi abambo a meningioma pambuyo pa chithandizo ndipo amakhala ndi chiopsezo chachikulu cha imfa. Kupulumuka kwa zaka zisanu m'zaka za m'ma grade meningioma kunafotokozedwa pa 87 peresenti poyerekezera ndi 29 peresenti ya maphunziro atatu.
Mosasamala mtundu wa meningioma, malo ndi kukula zingakhale zofunikira kwambiri pakuzindikira kufunikira ndi changu cha chithandizo. Chofunika kwambiri, komabe, ndi momwe munthu yemwe ali ndi meningioma akuchita mu moyo wawo wa tsiku ndi tsiku.
