(a and b) Enhanced T1-weighted MRI scan 4 months before the acute stage of
the pituitary apoplexy and (c and d) CT scan 3 months before the acute stage
of the pituitary apoplexy.. Pituitary macroadenoma (black arrows), right sphenoid sinus mucosal
thickening (white arrows), and a polypoid mass blocking the right choana
(grey arrows) are seen.

There was also mucosal thickening on the floor and lateral wall of the sphenoid sinus (Figure 1(a) and (b)). There were no signs of an evident skull base defect, but the cortex of the sella was narrow, indicating pressure erosion (Figure 1(c) and (d)).

sphenoid sinus and (b) T1-weighted sagittal view MRI sequence from the level
of the nasal septum demonstrating haemorrhage in a pituitary macroadenoma
(white arrows) and mucosal oedema and in the right sphenoid sinus (black
arrows).
