Magnetic resonance imaging (MRI) scans of the head demonstrating midline sphenoid bone mass. T1-weighted (FLAIR) sagittal view pituitary magnetic resonance imaging (MRI) scan performed in 2021 (A) demonstrating normal pituitary gland (short arrow) and adjacent midline T1-hypointense 3.0 cm × 2.3 cm × 2.3 cm mass (long arrow) located within the sphenoid bone extending to the clival, sphenoid sinus, and nasopharyngeal surfaces of the sphenoid bone with no extension into the sphenoid sinus or nasopharynx. Retrospective review of the T1-weighted sagittal view initial pituitary MRI scan performed in 2014 (B) demonstrated the same lesion within the sphenoid bone measuring 2.2 cm × 2.1 cm × 2.3 cm. Arrows are not included in (B) so the image is unperturbed and seen in the same way the radiologist viewed the scan.
