Posterior fossa bundu

Posterior fossa bundu rudzi rwehuropi bundu riri mukati kana padyo nepasi pehenya.

Iyo posterior fossa inzvimbo diki muhenya, inowanikwa padhuze neiyo brainstem uye cerebellum. Iyo cerebellum chikamu chehuropi chinotarisira kuenzanisa uye kufamba kwakabatana. Iyo brainstem inoitisa kudzora akakosha mashandiro emuviri, sekufema.

Kana bundu rikakura munzvimbo yepashure fossa, rinogona kudzivirira kuyerera kwepasipera mvura uye kukonzeresa kumanikidza pauropi uye musana.

Mazhinji mamota emashure epashure fossa ndiwo anonyanya cancer kenza. Vanotanga muuropi, pane kuti vapararire kubva kune imwe nzvimbo mumuviri.

Posterior fossa mamota haana zvikonzero zvinozivikanwa kana njodzi zvinhu.

Zviratidzo zvinowanzoitika nekukurumidza neashure fossa tumarara uye zvinogona kusanganisira:

• Kukotsira
• Kutemwa nemusoro
• Kusanzwisisika
• Nausea
• Kufamba zvisina kufanira (ataxia)
• Kusvipa

Zviratidzo zvinobva mumashure mafossa matota anoitikawo kana bundu rikakuvadza zvivakwa zvemuno, senge tsinga dzenyonganyonga. Zviratidzo zve cranial nerve kukuvara zvinosanganisira:

• Dilated vadzidzi
• Matambudziko eziso
• Kutarisana nemhasuru kushaya simba
• Kunzwa kurasikirwa
• Kurasikirwa kwekunzwa muchikamu chechiso
• Zvinetso zvekuravira
• Kusadzikama kana uchifamba
• Matambudziko ekuona

Kuongororwa kunoenderana neyakajeka nhoroondo yezvekurapa uye kuongorora kwemuviri, kuchiteverwa nekufungidzira bvunzo. Nzira yakanakisa yekutarisa yekupedzisira fossa ndeyeMRI scan. CT scans haina kubatsira kuona iyo nzvimbo yehuropi mune dzakawanda zviitiko.

Maitiro anotevera anogona kushandiswa kubvisa chidimbu chemuviri kubva pabundu kubatsira pakuongorora.

• Vhura kuvhiya kwehuropi, inonzi posterior craniotomy
• Stereotactic biopsy

Mazhinji mamota eiyo posterior fossa anobviswa nekuvhiya, kunyangwe kana asiri cancer. Kune nzvimbo shoma mu posterior fossa, uye bundu rinogona kutsimbirira pazvivakwa zvisina kusimba kana richikura.

Zvichienderana nerudzi uye saizi yebundu, kurapwa kwemwaranzi kunogona kushandiswa mushure mekuvhiyiwa.

Unogona kudzikisira kushungurudzika kwehurwere nekujoinha boka rekutsigira iro nhengo dzaro dzinogovana zvakajairika matambudziko nematambudziko.

Maonero akanaka anoenderana nekutsvaga cancer kare. Kuvharika kwakazara mukuyerera kwemvura yemuzongoza kunogona kutyisidzira hupenyu. Kana mamota akawanikwa kare, kuvhiyiwa kunogona kutungamira mukugara kwenguva refu.

Zvinetso zvinogona kusanganisira:

• Cranial tsinga palsies
• Herniation
• Hydrocephalus
• Kuwedzera kwekumanikidza kushushikana
