This study illustrates a number of important signs of how to distinguish a suprasellar mass from one arising from the pituitary:
- dural tail (blue arrow): helpful is suggesting that this is a meningioma (note that other tumours / conditions can do this too, e.g. lymphocytic hypophysitis, metastases)
- depression of the diaphragma sella (red arrow): in keeping the with mass pushing down into the sella, rather than rising out of the sella
- pituitary gland (yellow arrow) can be seen as separate from the mass (m) best seen on T2 weighted imageas.
