Sinus CT with sagittal (a) and coronal (b) reconstructions demonstrating a 5.0 x 2.7 x 2.5 cm hyperdense sphenoid mass with marked sphenoid expansion, suggestive of allergic fungal sinusitis. There is erosion of the sella, clivus, and a portion of the planum sphenoidale.

CT scan demonstrated a 5.0 x 2.7 x 2.5 cm hyperdense expansile mass in the right sphenoid sinus with erosion of the sella and clivus (Figure 1).
MRI of brain with sagittal view demonstrating expansile lesion centered in sphenoid sinus. The area with the signal void represents fungal debris. There is noticeable mass effect upon the sella with superior deviation of the pituitary gland and kinking of the infundibulum.

There was mass effect upon the sella with superior deviation of the pituitary gland and kinking of the infundibulum (Figure 2).
(a) GMS stain demonstrating scattered noninvasive fungal hyphae. (b) H&E stain showing allergic mucin and lamellated inflammatory debris with numerous eosinophils and Charcot-Leyden crystals.
