Adenoma yebhinqa. Iimpawu, ngezigaba

adenoma pituitary i neoplasm nabungozi lomlinganiswa. It ivela kwiiseli ithumba kwi yebhinqa lobe sobuKristu. Yenzelwe neoplasm e sella, emazantsi, yaba lukakayi (nesabelo salo tapered). Ngokuqhelekileyo, le adenoma yebhinqa banesifo kwizigulane phakathi kweminyaka engama-20 ukuya kuma-40 ubudala. Ubukhulu becala kuphuhliso yamathumba abafazi sifo. Ngokutsho manani, 22 ukuya kuma-30% azo zonke yamathumba intracranial yi ithumba yebhinqa. Iimpawu izifo zenzeka, kuxhomekeka yokuhlela.

ukubunjwa ebubonisayo inokuba hormonally iyasebenza hormonally engasebenziyo.

Udidi lokuqala luquka yamathumba esikwaziyo ukuvelisa iihomoni utshixelo. Ukwenziwa adenomas hormonally esebenzayo ibonisa enesiqulatho serum omkhulu kwezi hormone (utshixelo) kunye nobukho syndrome lwezonyango ngayo ngokwaneleyo. Lesi sifo ngenxa yokwanda imveliso nokuba hormone. Ngokuba ama-esebenzayo yamathumba ziquka prolactinoma (prolactin-ezivelisa) kortikotropinomy (ukuvelisa corticotropin, somatotropin (secreting hormone ukukhula - zezith) kunye nezinye kufuneka kuqatshelwe ukuba phantse isiqingatha adenomas hormonally esebenzayo kwenza prolactinoma ..

Benza i yinxalenye encinane yamathumba hormonally engasebenziyo.

Enobubanzi engaphantsi kwe-10 ukuyilwa mm kwenzeka microadenomas yebhinqa.

Izizathu kuphuhliso yamathumba bafunda ukuza kuthi ga ngoku akwanelanga.

Ngokutsho komnye iingqiqo, kukho sisilonda esidumbileyoesingaphakathi iphambili le ngxenye kunye nokubandakanyeka yesibini isicwili ithumba kule nkqubo. Ngokutsho komnye ingqiqo, kukho sisilonda esidumbileyoesingaphakathi lokuqala, oluthi luqokelelane ngenxa yebhinqa adenoma.

Iimpawu yamathumba hormonally-active ziquka yonyango kunye pathways syndrome, kwaye radiographic ukubonakaliswa oftalmonevrologicheskie.

Ngamandla obubonakala uphawu ezidalwe-exchange kubonisa uyondelelwano lwee- hormone ngokugqithiseleyo kwaye iqondo umonakalo inyama ojikeleze neoplasm.

iimpawu Oftalmonevrologicheskie lidiza of yebhinqa adenoma, elizimeleyo ukususela ekukhuleni kwayo suprasellar. Kule uxinzelelo entsha uluhlu uvalo kwi iinqwelo Turkish Uxhokonxwa yintloko umlinganiswa buthuntu. Ngokuqhelekileyo, iintlungu ephelekwa isicaphucaphu hayi komntu akuxhomekekanga ekuzithandeleni umntla kwaye azisoloko kuphele ntlungu.

Umonakalo kwizakhiwo e hypothalamic yebhinqa adenoma ikhula bakuphathe. Iimpawu kusenzwa andise neoplasm ndimenzele enkalweni lweHo- ngeempumlo kunye CSF imvakalelo ingxinano ngeempumlo. Ukukhula neoplasms, ukumqumbisa ucinezelo yamasebe ka-luvo cranial, sasihamba ophthalmoplegia (izitshanguba eye kwezihlunu) kunye diplopia (umbono kabini).

Kama obukhulu, kodwa hayi legazi esibulalayo ngazo kwakhiwe entsha. Kuye kwafumaniseka ukuba lo gama adenoma yebhinqa, apho iimpawu yongeniselo legazi, ukuze bandiqumbise "unyango" kulogo. Ngokuqhelekileyo, le ziyenzeka uphawu ngakumbi prolactin.

Ngexa lokukhulelwa, ngokuqhelekileyo kwandisa yebhinqa adenoma.

Iimpawu ezenza ngethuba loviwo radiographic, ochazwa utshintsho ngobukhulu kunye yeemilo sella turcica, ukuthotywa kunye ukuxozwa kwezakhiwo bone, njalo njalo. CT nga libonwa ngokwayo adenoma yebhinqa.

Iimpawu ezithile yamathumba enama-esebenzayo abe umlinganiswa ethile. Kwezinye iimeko, prolactinomas kwabasetyhini zingavela galactorrhea (imixholo njengamasi kwakhululwa incum), okanye yezitenxo exesheni. Kudla zabonakala ezidityanisiweyo zezi mpawu.
