1. Two patients with chordoma involving the sphenoid bone.
Two patients with chordoma involving the sphenoid bone. A, An 18-year-old male patient. Axial T2WI shows a multicystic lesion involving the central skull base, including the sphenoid bone, sphenoid sinus, posterior ethmoids, and left middle cranial fossa. Focal areas of T2 hyperintensity are seen. B, In the coronal reformatted image, a bone window shows dehiscence of the planum sphenoidale (arrow). C, An 11-year-old boy with chordoma. Sagittal noncontrast T1WI shows the lesion to nearly fill the sphenoid sinus. There is a small residual aerated portion of the sphenoid sinus cavity (arrow). D, Photomicrograph shows that neoplastic epithelioid cells form cords in a mucoid background (HE staining; original magnification ×40).
