- •
A midline dural filum on the sella is a useful landmark of transsphenoidal approach.
- •
The dural filum significantly co-exists with a midline septum in the sphenoid sinus.
- •
The dural filum also co-exists with ossification in the sphenoid sinus remarkably.
- •
Tethering of sellar dura is suggested as a developmental mechanism of the filum.
