Admission computed tomography (CT) scan revealed the left frontal lobe contusion and an intrasellar pituitary incidentaloma (Figure 1).
T1-weighted (upper left) and T2-weighted (upper right) axial images obtained at 4 days after admission, and contrast-enhanced T1-weighted axial (lower left) and coronal (lower right) images obtained at 5 days after admission. Magnetic resonance images show that there is no traumatic lesion causing an oculomotor nerve palsy but reveal hemorrhage in an intrasellar mass, which is compressing the left cavernous sinus (arrow), associated with the sphenoid sinus mucosa thickening (arrowhead).

Repeated CTs and magnetic resonance images showed that there were no traumatic lesions causing the oculomotor nerve palsy, the left cavernous sinus was compressed by an intratumoral nonenhancing area suggesting hemorrhage, and tumor size was unchanged compared with the admission CT, but sphenoid sinus mucosa was progressively thickened after admission (Figures 2 and 3).
Repeated computed tomography showing that the sphenoid sinus mucosa thickening (arrowhead) is progressively aggravated from admission to 6 days after admission.
