Sellar region

Sellar region is a small area in the central nervous system (CNS) that includes the sella turcica, cavernous sinus, suprasellar cistern, and pituitary gland.^[1] The pituitary gland is located in the sella turcica, a saddle-shaped indentation in the sphenoid bone at the base of the skull.^[2] The most common tumours in the sellar region are anterior pituitary adenomas, followed by tumors from the posterior pituitary.^[3] Magnetic resonance imaging is the preferred imaging method for detecting sellar conditions.^[4] The sellar region is surrounded by important structures: the brainstem and basilar artery behind the optic nerves, optic chiasm, and circle of Willis above, and the carotid arteries and cavernous sinus on the sides.^[5] Surgery is often the primary treatment for sellar lesions, allowing for tumor removal and pathological analysis.^[6] A sellar mass can cause hormone imbalances, vision problems, or headaches. Sometimes, it is found by chance during a brain scan for another reason.^[7]
