Sellar region
Anatomical terminology [edit on Wikidata]

Sellar region is a small area in thecentral nervous system (CNS) that includes thesella turcica,cavernous sinus, suprasellar cistern, andpituitary gland.^[1] The pituitary gland is located in the sella turcica, a saddle-shaped indentation in thesphenoid bone at the base of theskull.^[2] The most commontumours in the sellar region areanterior pituitary adenomas, followed by tumors from theposterior pituitary.^[3]Magnetic resonance imaging is the preferred imaging method for detecting sellar conditions.^[4] The sellar region is surrounded by important structures: thebrainstem andbasilar artery behind theoptic nerves,optic chiasm, andcircle of Willis above, and thecarotid arteries and cavernous sinus on the sides.^[5]Surgery is often the primary treatment for sellar lesions, allowing for tumor removal andpathological analysis.^[6] A sellar mass can causehormone imbalances,vision problems, orheadaches. Sometimes, it is found by chance during abrain scan for another reason.^[7]
