ʻO ka tumo posterior fossa

ʻO ka tumo posterior fossa kahi ʻano tumo lolo i loaʻa a i ʻole ma lalo o ka iwi poʻo.

ʻO ka fossa hope kahi wahi liʻiliʻi i ka iwi poʻo, i loaʻa ma kahi o ka lolo a me ka cerebellum. ʻO ka cerebellum kahi ʻāpana o ka lolo e kuleana no ke kaulike a me nā neʻe i hoʻohui ʻia. ʻO ka lolo ka kuleana no ka kaohi ʻana i nā hana o ke kino, e like me ka hanu ʻana.

Inā ulu ka tumo ma kahi o ka fossa hope, hiki iā ia ke pale i ke kahe o ka wai o ka iwi a hoʻonui i ke kaomi ma ka lolo a me ka iwi kuamoʻo.

ʻO ka hapa nui o nā tumors o ka fossa hope he maʻi maʻi ʻōpū mua. Hoʻomaka lākou i ka lolo, ma mua o ka hoʻolaha ʻana mai kahi ʻē aʻe o ke kino.

ʻAʻole ʻike ʻia nā tumors posteros fossa a me nā kumu weliweli.

Kū koke nā ʻōuli me nā tumors fossa hope a komo pū paha:

• Hiamoe
• ʻEha poʻo
• Kaulike ʻole
• Nusea
• Hele wāwae (ataxia)
• ʻO ka luaʻi

Hana ʻia nā ʻōuli mai nā tumo fossa hope i ka wā e hōʻino ai ka tumo i nā hale kūloko, e like me nā ʻāʻī cranial. Nā hōʻailona o ka hōʻino nerve cranial e komo pū:

• Nā haumana Dilated
• Nā pilikia maka
• Nawaliwali nā mākala ke alo
• Lohe hoʻolohe
• ʻO ka nalowale o ka manaʻo ma kahi o ka maka
• Nā pilikia ʻono
• Kūleʻa ʻole ke hele wāwae
• Nā pilikia ʻike

Hoʻokumu ʻia ka diagnostics ma kahi moʻolelo olakino piha a me ka hoʻokolohua kino, a ukali ʻia e nā hoʻokolohua kiʻi. ʻO ke ala ʻoi loa e nānā i ka fossa hope me kahi scan MRI. ʻAʻole kōkua ʻo CT scans e ʻike i kēlā ʻāpana o ka lolo i ka nui o nā hihia.

Hiki ke hoʻohana ʻia nā kaʻina hana e wehe ai i kahi ʻāpana o ke kiko mai ka tumo e kōkua me ke kuhi.

• ʻOki poepoe lolo, i kapa ʻia he craniotomy hope
• ʻO Biopsy Stereotactic

ʻO ka hapa nui o nā tumors o ka fossa hope e hoʻoneʻe ʻia me ke kahakaha, ʻoiai ʻaʻole lākou he maʻi maʻi. Aia ka palena o ka wahi ma ka hope fossa, a hiki i ka tumo ke kaomi maʻalahi i nā hale lahilahi ke ulu ia.

Kaukaʻi ʻia i ka ʻano a me ka nui o ka tumo, hoʻohana pū ʻia ka hoʻolāʻau radiation ma hope o ke kaha ʻana.

Hiki iā ʻoe ke hoʻomāmā i ke koʻikoʻi o ka maʻi ma ke komo ʻana i kahi hui kākoʻo nāna nā lālā e kaʻana like i nā ʻike a me nā pilikia.

Aia kahi kuanaʻike maikaʻi i ka loaʻa mua ʻana o ka maʻi ʻaʻai. Hiki ke hoʻoweliweli i kahi blockage āpau i ke kahe o ka wai spinal. Inā loaʻa nā tumors i ka wanaʻao, hiki i ke kīpoki ke alakaʻi i ke ola lōʻihi.

Komo pū nā pilikia:

• Palsies nerve Cranial
• ʻO Herniation
• ʻO Hydrocephalus
• Hoʻonui i ka kaomi intracranial

Kāhea i kāu mea mālama ola inā loaʻa ʻoe i nā poʻo o ke poʻo maʻamau me ka nausea, ka luaʻi, a i ʻole nā ​​loli ʻike.
