Tuberculum sellae is a bony prominence located at the midline in the middle cranial fossa of the skull. It is an important landmark in neurosurgery and radiology due to its proximity to the pituitary gland, which lies just below it. Some synonyms for this term include the sellar tubercle, sellar eminence, or sella turcica. The word "sellae" derives from the Latin "sellae" meaning saddle, describing the shape of the bony ridge. Understanding the various synonyms of tuberculum sellae is important for medical professionals dealing with pituitary gland pathology and skull base surgical approaches, as they can ensure clear and effective communication with colleagues and patients.
