Figure 1: Schematic diagram showing bromocriptine/cabergoline-induced CSF rhinorrhea. (a) Normal sella, pituitary (green), sphenoid sinus (grey), and CSF spaces (blue). (b) Widening of the sella due to erosion by the pituitary tumor (brown). (c) Shrunken tumor after bromocriptine/ cabergoline therapy resulting in CSF rhinorrhea
