Computed tomography of the sellar spine

Area of Science:

• Radiology
• Anatomical Pathology
• Neurosurgery

Background:

• The sellar spine is a rare osseous anatomical variant.
• It arises from the anterior aspect of the dorsum sellae, projecting centrally into the sella turcica.
• Previous descriptions relied on gross specimens and plain radiography.

Observation:

• This report details the computed tomography (CT) scan findings in a patient with a sellar spine.
• The CT scan clearly delineated the osseous spine's morphology and location.
• The study focused on visualizing this structure using advanced CT imaging.

Findings:

• CT scans successfully identified the sellar spine, confirming its presence and anatomical characteristics.
• The imaging demonstrated that the surrounding structures within the sella turcica appeared normal.
• This represents the first reported CT scan visualization of a sellar spine.

Implications:

• CT imaging provides a detailed, non-invasive method for diagnosing the sellar spine.
• Understanding this variant is crucial for accurate interpretation of sellar region imaging.
• This finding aids neurosurgeons and radiologists in differentiating normal variants from pathology.
