Adenoma pituitary. Izimpawu, ngezigaba

adenoma pituitary kuyinto neoplasm ingozi yohlamvu. It evela isimila cells e anterior pituitary Lobe. Kuhunyushelwe neoplasm e sella, ngasesinqeni se ugebhezi (ingxenye yayo tapered). Njengomthetho, le adenoma pituitary sitholakale iziguli abaneminyaka ephakathi kwengu-20 kuya kwengu-40 ubudala. Ngokwezinga elikhulu ekuthuthukiseni izimila abesifazane singangena. Ngokwezibalo, 22 kuya ku-30% azo zonke izimila intracranial kuyinto isimila pituitary. Ngezimpawu zesifo zenzeka, kuye ngezigaba.

kumiswa Benign kungenzeka hormonally asebenzayo futhi hormonally esingasebenzi.

Isigaba sokuqala sihlanganisa izimila uyakwazi ukukhiqiza ama-hormone utho. Ukwakheka adenomas hormonally asebenzayo libonisa serum wokuqukethwe lelisetulu la ma-hormone (utho) kanye nokuba khona syndrome emitholampilo ngokwanele wazwakalisa. Lesi sifo kuwumphumela umkhiqizo wawanda noma hormone. Ukuze izimila-hormone okuthiwa i-esebenzayo zihlanganisa prolactinoma (prolactin ezikhiqiza) kortikotropinomy (esikhiqiza corticotropin, somatotropin (secreting ozokusebenzisa - STH) kanye nezinye Kumele kuqashelwe ukuthi cishe isigamu se-adenomas hormonally asebenzayo eziyimisebenzi prolactinoma ..

Akha ingxenye encane izimila hormonally esingasebenzi.

Nge ububanzi engaphansi kuka-10 mm kumiswa kwenzeka microadenomas pituitary.

Izizathu ukuthuthukiswa izimila esezihloliwe kuze kube manje akwanele.

Ngokusho kwelinye imiqondo, kukhona lesion oyinhloko le ngxenye nge ukuzibandakanya yesibili izicubu isimila enqubeni. Ngokusho komunye umqondo, kukhona lesion eyinhloko, kwakhiwa ngenxa pituitary adenoma okuyinto.

Izimpawu izimila hormonally-asebenzayo zihlanganisa endocrine kanye umzimba syndrome, futhi radiographic ukubonakaliswa oftalmonevrologicheskie.

Ukugxila ukubonakaliswa endocrine-exchange uhlamvu kuveza lokuhlushwa i-hormone ekhiqizwa ngokweqile nokuthi leso senzo senziwe ukulimala ijwabu ezungeze neoplasm.

izimpawu Oftalmonevrologicheskie ezisikisela pituitary adenoma, zizimele kusukela ekukhuleni kwayo suprasellar. Kulesi kumiswa ingcindezi entsha ku diaphragm ku sehhashi Turkish kuphakamisa bekhanda uhlamvu buthuntu. Ngokuvamile, ubuhlungu ephelezelwa isicanucanu hhayi akuxhomekile le esifubeni futhi ngaso sonke isikhathi aqedwa amaphilisi ezinhlungu.

Ukulimala izakhiwo e hypothalamic pituitary adenoma ikhula kuphakamisa. Izimpawu phansi esiphelweni neoplasm ingase ibonise ukudlula ngalo ingaphakathi acinene kanye CSF umuzwa ukuminyana acinene. Kukhula neoplasms, ingqondo kokucindezelwa amagatsha ka nezinzwa cranial, ephelezelwa ophthalmoplegia (iso imisipha izilonda) kanye diplopia (umbono double).

Inkinga severe, kodwa hhayi ukopha ebulalayo kubhekwa ukwakheka entsha. Kwatholakala ukuthi kuyilapho adenoma pituitary lapho izimpawu ukopha ukwanda, angase avuse nokuguqulwa ngaleli "khambi". Ngokuvamile, lokhu mkhuba sici ngaphezulu prolactin.

Phakathi nenkathi yokukhulelwa, ngokuvamile kwandisa pituitary adenoma.

Izimpawu sezempi ngesikhathi luhlolo radiographic oluboniswa izinguquko ezinobukhulu nomumo we sella turcica, nokucekelwa futhi thinning ithambo izakhiwo, kanjalonjalo. CT singasetshenziswa visualized uqobo adenoma pituitary.

Izimpawu ezinye izimila-hormone okuthiwa i-esebenzayo abe umlingisi ethize. Kwezinye izimo, prolactinomas kwabesifazane kungase kubonakale galactorrhea (okuqukethwe Milky ukukhululwa isifuba), noma ukuphazamiseka kokuya esikhathini. Ngokuvamile zabonakala elihlangene zalezi zimpawu.
