Pituitary microadenoma

microadenomas pituitary libhekisela izimila ingozi futhi isukela Lobe amaseli ayo anterior. I kwasendaweni yesimila is nasemkhakheni sella. Kufika 30% azo zonke izimila intracranial ka adenoma (microadenomas) pituitary. It is ikakhulukazi ezitholakala kubantu kusukela kwabaneminyaka engamashumi amabili kuya amane. Uma kutholwa kwabesifazane zenzeka kaningi amadoda.

pituitary microadenoma ungaba umehluko okukhulu kusukela macroadenoma. Umehluko kuzibonakalisa kwasekuqaleni, ngosayizi. microadenomas pituitary has a ububanzi amamilimitha angu engaphansana kweshumi. Ngaphezu kwalokho, ezahlukene kanye Yiqiniso emitholampilo ekuphenduleni izinhlobo ezahlukene yokwelapha esetshenziswa. Tumorlet has a capsule kancane evelele noma ukungezwakali kwawo.

Kufanele kuqashelwe ukuthi iningi izimila kunezimpawu morphological umdlavuza. Nokho, abaningi bathambekele sikhule ku ubuchopho (egobolondweni kanzima) kanye amathambo aqatha ezizungezile indlala pituitary.

Adenoma (microadenomas) pituitary. izimpawu

Hormonally izimila ngasebenzi musa abangele ukwephula ngokucacile endocrine-exchange uhlamvu. Ukubonakaliswa emitholampilo izimila hormonally-asebenzayo ihlanganisa endocrine kanye umzimba syndrome, futhi radiographic izimpawu oftalmonevrologicheskie. NoBukhulu iziyaluyalu endocrine-umzimba ibonisa izinga umonakalo ezizungezile isimila nezicubu.

Oftalmonevrologicheskih ukubonakaliswa izimpawu kuyinto eyinhloko yoma we izinzwa optic, ekushintsheni ensimini umbono. umfutho wabo incike ukukhula adenoma suprasellar (microadenomas). Ingcindezi yesimila ku endaweni sella diaphragm kubangela ikhanda ukuthi itholakala ku temporal, engaphelele kanye pozadiglaznichnoy ndawo. Njengomthetho, it is hhayi ephelezelwa nesicanucanu akuxhomekile isikhundla umzimba. Akukhona njalo kungenzeka ukuba asuse imithi. Landela up isimila ukukhula kuholela ukunqoba izakhiwo hypothalamic. ukukhula isimila bebheke kule ndawo phansi turcica sella, wayimboza ku itheku engaveza lokujabulela acinene ukucinana ukuzihlalela therefrom le CSF (cerebrospinal fluid).

I ukwanda okukhulu kwezincwadi ubuhlungu futhi oftalmonevrologicheskih izimpawu ngokujwayelekile ohambisana nesifanekiso kwemibala anda ukuthuthukiswa isimila (isb, ukukhulelwa), noma ukopha ku lwesimila. Njengoba umkhuba ubonisa, ukopha - njalo ngokwanele, sina kodwa hhayi inkinga ebulalayo. Kwezinye izimo, kuba akugcini ngokuletha umuzwa ubuhlungu anda, ukuphazamiseka visual, kodwa "Ukuphulukisa" okungazelelwe yesimila.

izimpawu Radiographic ekushintsheni usayizi kanye ukuma Turkish sehhashi, ekubhujisweni thinning ithambo izakhiwo kanye nezinye izinto. Kwezinye izimo kungenzeka ngeso yesimila (-CT scan).

Adenoma (microadenomas) pituitary. ukwelashwa

Kuye ngohlobo, kobukhulu izimpawu, kobukhulu kanye nosayizi yokwelapha kuhlanganiswe lenikiwe.

In the ukungabikho ezibukwayo iziyaluyalu hormonally asebenzayo isimila ezifana prolactinoma, iphathwa indlela olandelanayo usebenzisa Dopamine yokwamukela agonists. Ukuze izindlela refractory op esetshenziswa imithi nezimila. Njengomthetho, wasebenzisa microsurgery. Izimila yobukhulu enkulu ibhekane neurosurgery. Ngemva kokuhlinzwa, ukwelashwa ngemisebe umiswa.

Kwezinye izimo seziguli ezisencane ngemihlume noma okusesilinganisweni kobukhulu ukubonakaliswa nge isifo Cushing sika noma syndrome, Nelson uqoke zangaphandle ugongolo radiotherapy. Ukuze izimila Ubukhulu ezincane ngokuvamile sisetshenziswa ngemisebe-proton.

Ukuze adenomas hormonally ngasebenzi zisebenzisa ukuhlinzwa futhi ukwelashwa ngemisebe.
