sellar tumour
Medical term for a tumor located in the sella turcica region of the skull. Used in clinical contexts.
An MRI scan confirmed a sellar tumour.
Compound of トルコ鞍部 (toruko anbu, 'sella turcica') and 腫瘍 (shuyō, 'tumour'). The term is a direct medical borrowing, likely from Western anatomical terminology.
