CT - CT brain
Axial non-contrast
Axial bone window
What is the best next investigation?
CT angiography. Non-invasive and will be able to better define vascular abnormality.
Non-contrast CT of the brain demonstrates no parenchymal abnormality. There is however some increased density within the sella turcica. The superior ophthalmic veins are prominent.
Windowing to bone demonstrates erosion of the sella, with protrusion of soft tissue material into the sphenoid sinus.
