Sella syndrome engenanto

I-sella syndrome engenanto yimeko apho i-pituitary gland iyancipha okanye icabalele.

I-pituitary yincindi encinci ebekwe ngaphantsi kwengqondo. Iqhotyoshelwe emazantsi engqondo ngesiqu sepituitary. Indawo yokuhlala ihlala kwigumbi elifana nesali kwindawo yokakayi ebizwa ngokuba yi-sella turcica. KwiLatin, oko kuthetha isihlalo saseTurkey.

Xa i-pituitary gland iyancipha okanye icaba, ayinakubonwa kwiskena se-MRI. Oku kwenza ukuba indawo yedlala lengqula ibonakale ngathi yi "sella engenanto." Kodwa i-sella ayinanto. Ihlala igcwele ulwelo lwe-cerebrospinal fluid (CSF). I-CSF lulwelo olujikeleze ingqondo kunye nentambo yomqolo. Nge-sella syndrome engenanto, i-CSF ingene kwi-sella turcica, ibeka uxinzelelo kwi-pituitary. Oku kubangela ukuba incindi inciphise okanye icabale.

Isiseko se-sella syndrome esingaqhelekanga senzeka xa olunye lomaleko (arachnoid) lugquma ingaphandle lengqondo luyehla kwi-sella kwaye licinezela kwi-pituitary.

I-sella syndrome yesibini engenanto yenzeka xa i-sella ingenanto kuba i-pituitary gland yonakaliswe:

• Ithumba
• Unyango ngemitha
• Ugqirha
• Umonzakalo

I-sella syndrome engenanto inokubonakala kwimeko ebizwa ngokuba yi-pseudotumor cerebri, echaphazela ikakhulu abancinci, abafazi abatyebe kakhulu kwaye ibangela ukuba i-CSF iphantsi koxinzelelo oluphezulu.

Idlala lengqula lenza iihomoni ezininzi ezilawula amanye amadlala emzimbeni, kubandakanya:

• Amadlala adrenal
• Amaqanda
• Amatyhalarha
• Idlala lengqula

Ingxaki nge-pituitary gland inokukhokelela kwiingxaki ngayo nayiphi na kwezi ndlala zingasentla kunye nakwinqanaba lamahomoni angaqhelekanga kula madlala.

Rhoqo, akukho zimpawu okanye ilahleko yomsebenzi wepituitary.

Ukuba kukho iimpawu, zinokubandakanya oku kulandelayo:

• Iingxaki zokwakhiwa
• Intloko ebuhlungu
• Ukuya exesheni ngokungaqhelekanga okanye ukungabikho
• Ukunciphisa okanye akukho mnqweno wesini (i-libido ephantsi)
• Ukudinwa, amandla aphantsi
• Ukukhutshwa kwengono

Isiseko se-sella syndrome esisisiseko sihlala sifunyanwa ngexesha le-MRI okanye i-CT scan entloko nakwingqondo. Umsebenzi wePituitary uhlala uqhelekile.

Umboneleli wezempilo unoku-odola uvavanyo ukuze aqiniseke ukuba idlala lepituitary lisebenza ngesiqhelo.

Ngamanye amaxesha, iimvavanyo zoxinzelelo oluphezulu kwingqondo ziya kwenziwa, ezinje:

• Uviwo lwe-retina ngugqirha wamehlo
• Ukugqobhoza iLumbar (impompo yomqolo)

Kwiprayimari yesella syndrome engenanto:

• Akukho lunyango ukuba umsebenzi we-pituitary uqhelekile.
• Amayeza anokumiselwa ukuba anyange nawaphi na amanqanaba ehomoni angaqhelekanga.

Kwi-sella syndrome yesibini engenanto, unyango lubandakanya ukubuyisela ii-hormone ezingekhoyo.

Ngamanye amaxesha, kufuneka kwenziwe utyando ukulungisa i-sella turcica.

Isiseko se-sella syndrome asibangeli zingxaki zempilo, kwaye asichaphazeli ubude bexesha lokuphila.

Iingxaki zesella syndrome ezingenanto zibandakanya inqanaba elincinci ngaphezulu kweprolactin. Le hormone yenziwa yi-pituitary gland. Iprolactin ivuselela ukukhula kwamabele kunye nemveliso yobisi kubafazi.

Ubunzima besifo se-sella sesekondari esingenanto sinxulumene nesizathu sesifo se-pituitary gland okanye kwimiphumo ye-hormone encinci ye-pituitary (hypopituitarism).

Nxibelelana nomboneleli wakho ukuba unempawu ezingaqhelekanga zomsebenzi wepituitary, ezinje ngeengxaki zokuhamba sexesheni okanye ukungabi namandla.
