Abstract
The sellar spine is a bony intrasellar spine arising on the midline from the inferior portion of the anterior aspect of the dorsum sellae and protruding into the pituitary fossa. The sellar spine corresponds to the ossified remnant of the cephalic tip of the notochord. If unrecognized, the sellar spine can lead to misinterpretation of MRI of the pituitary region.
