Video: 5 terrible places where it is better not to go!

Posterior fossa tumor ke mofuta oa hlahala ea bokong e kahare kapa ka tlase ho lehata.

The posterior fossa ke sebaka se senyenyane ka har'a lehata, se fumanoang haufi le brainstem le cerebellum. Cerebellum ke karolo ea boko e ikarabellang bakeng sa botsitso le tsamaiso e tsamaellanang. Brainstem e ikarabella bakeng sa ho laola mesebetsi ea bohlokoa ea 'mele, joalo ka ho hema.

Haeba hlahala e hola sebakeng sa poso fossa, e ka thibela phallo ea mokelikeli oa mokokotlo mme ea baka khatello e eketsehileng bokong le mokokotlong.

Boholo ba lihlahala tsa posterior fossa ke mofetše oa mantlha oa kankere. Li qala bokong, ho fapana le hore li hasane ho tloha kae kae 'meleng.

Lihlahala tsa poso ea fossa ha li na lisosa tse tsebahalang kapa lisosa tsa kotsi.

Matšoao a hlaha kapele haholo ka lihlahala tsa poso tsa fossa mme a ka kenyelletsa:

  • Ho otsela
  • Ho opeloa ke hlooho
  • Ho se leka-lekane
  • Ho nyekeloa
  • Maeto a sa tsamaellanang (ataxia)
  • Ho hlatsa

Matšoao a tsoang liholong tsa morao-rao tsa fossa le ona a hlaha ha hlahala e senya likarolo tsa lehae, joalo ka methapo ea methapo. Matšoao a tšenyo ea methapo ea methapo a kenyelletsa:


  • Barutoana ba hlakileng
  • Mathata a mahlo
  • Tobana le bofokoli ba mesifa
  • Ho lahleheloa ke kutlo
  • Ho lahleheloa ke maikutlo karolong e 'ngoe ea sefahleho
  • Mathata a tatso
  • Ho se tsitse ha u tsamaea
  • Mathata a pono

Tlhahlobo e ipapisitse le nalane e felletseng ea bongaka le tlhahlobo ea 'mele, e lateloang ke liteko tsa litšoantšo. Mokhoa o motle oa ho sheba pososos fossa ke ka ho hlahloba MRI. Lisebelisoa tsa CT ha li thuse ho bona sebaka seo sa boko maemong a mangata.

Mekhoa e latelang e ka sebelisoa ho tlosa sengoathoana sa lisele ho tsoa ho hlahala ho thusa ka ho tseba:

  • Bula opereishene ea boko, e bitsoang posterior craniotomy
  • Tlhatlhobo ea stereotactic

Boholo ba lihlahala tsa posterior fossa lia tlosoa ka ho buuoa, leha li se na mofetše. Ho na le sebaka se lekanyelitsoeng kamorao ho fossa, 'me hlahala e ka hatella habonolo mehahong e thata ha e hola.

Ho ipapisitse le mofuta le boholo ba hlahala, kalafo ea radiation e ka sebelisoa hape kamora ho buuoa.

U ka fokotsa khatello ea maikutlo ea bokuli ka ho kenella sehlopheng sa ts'ehetso seo litho tsa sona li arolelanang liphihlelo le mathata a tšoanang.


Pono e ntle e ipapisitse le ho fumana mofets'e kapele. Thibelo e felletseng ea phallo ea mokelikeli oa mokokotlo e ka beha bophelo kotsing. Haeba lihlahala li fumanoa kapele, ho buuoa ho ka lebisa ho pholoheng nako e telele.

Mathata a ka kenyelletsa:

  • Metsing ea cranial palsies
  • Tlhoekiso
  • Hydrocephalus
  • Khatello e eketsehileng ea khatello ea kelello

Bitsa mofani oa tlhokomelo ea bophelo haeba u lula u opeloa ke hlooho ka lebaka la ho nyekeloa ke pelo, ho hlatsa kapa ho fetoha ha pono.
