Ithumba elingasemva

I-posterior fossa tumor luhlobo lwethumba lobuchopho elikufuphi okanye ezantsi kwekhakhayi.

I-posterior fossa yindawo encinci kwikakayi, efumaneka kufutshane ne-brainstem kunye ne-cerebellum. I-cerebellum yinxalenye yengqondo ejongene nokulingana kunye nokuhamba okulungelelanisiweyo. I-brainstem inoxanduva lokulawula imisebenzi ebalulekileyo yomzimba, njengokuphefumla.

Ukuba ithumba likhula kwindawo ye-posos fossa, inokuthintela ukuhamba komgogodla kwaye ibangele uxinzelelo olukhulu kwingqondo nakumqolo.

Uninzi lwamathumba angasemva kwe-fossa zii-cancer zomqondo eziphambili. Ziqala kwingqondo, kunokuba zisasazeke ukusuka kwenye indawo emzimbeni.

Amathumba angasemva e-fossa awanazo izizathu okanye umngcipheko.

Iimpawu zivela kwangoko kakhulu ngamathumba angasemva kwefossa kwaye zinokubandakanya:

• Ukozela
• Intloko ebuhlungu
• Ukungalingani
• Isicaphucaphu
• Ukuhamba okungahambelaniyo (ataxia)
• Ukuhlanza

Iimpawu ezivela kwizicwili zangasemva ze-fossa zenzeka xa ithumba lonakalisa izakhiwo zalapha ekhaya, ezinje nge-cranial nerves. Iimpawu zomonakalo wemithambo-luvo zibandakanya:

• Abafundi abaqaqambileyo
• Iingxaki zamehlo
• Jongana nobuthathaka bemisipha
• Ukuphulukana nokuva
• Ukuphulukana nemvakalelo kwinxalenye yobuso
• Iingxaki zokungcamla
• Ukungazinzi xa uhamba
• Iingxaki zombono

Ukuchongwa kwesifo kusekwe kwimbali yezonyango kunye novavanyo lomzimba, kulandele iimvavanyo zokucinga. Eyona ndlela yokujonga ifossa yangasemva kukuskena kweMRI. Ukuvavanywa kwe-CT akuncedi nganto ukubona loo ndawo yengqondo kwiimeko ezininzi.

Ezi nkqubo zilandelayo zingasetyenziselwa ukususa isiqwenga seethishu kwithumba ukunceda isifo.

• Utyando lwengqondo oluvulekileyo, olubizwa ngokuba yi-craniotomy yangasemva
• I-biopsy yestereotactic

Uninzi lwamathumba angasemva kwe-fossa asuswe ngotyando, nokuba awunamhlaza. Kukho indawo encinci kwifossa yangasemva, kwaye ithumba linokucinezela ngokulula kwizakhiwo ezibuthathaka ukuba liyakhula.

Kuxhomekeke kudidi kunye nobungakanani bethumba, unyango lwemitha lunokusetyenziswa emva kotyando.

Ungaluphelisa uxinzelelo lokugula ngokujoyina iqela lenkxaso elinamalungu abelana ngamava aqhelekileyo kunye neengxaki.

Umbono olungileyo uxhomekeke ekufumaneni umhlaza kwangoko. Ukuvaleka okupheleleyo kokuhamba kwemisipha yomqolo kunokuba yingozi ebomini. Ukuba amathumba afunyenwe kwangethuba, utyando lunokukhokelela ekusindeni ixesha elide.

Iingxaki zinokubandakanya:

• I-cranial palsies yenyani
• Ubungqina
• IHydrocephalus
• Ukunyuka koxinzelelo lwangaphakathi

Shayela umniki-nkonzo wakho wezempilo ukuba unesiqhelo esibuhlungu esenzeka rhoqo ngesicaphucaphu, ukugabha, okanye ukutshintsha kombono.
