case_images: Sagittal magnetic resonance imaging (MRI) with contrast; large homogeneous mass occupying the sella turcica, sphenoid sinus, and prepontine cistern; the infundibulum is minimally deviated to the right and normal pituitary appears to be elevated and is seen underneath the optic chiasm

case_images: The MRI showed gross total resection [Figures 5 and 6].
case_images: Sagittal contrast enhanced magnetic resonance imaging (MRI) shows resection of the majority of the sellar/suprasellar mass with thickening and nodular enhancement along the clivus. (a) Recurrence of the mass. After repeat endoscopic resection of the lesion (b)

case_images: The MRI showed gross total resection [Figures 5 and 6]. Although the patient was asymptomatic, we performed a routine surveillance MRI six months after surgery, given the rarity of the lesion, which showed a recurrence of the mass [Figure 6a]. We performed repeat endoscopic resection of the lesion [Figure 6b], and follow-up imaging six months after surgery shows no further recurrence.
