FIG 2. Images in a 50-year-old woman with a dural AVF draining into the right cavernous sinus (case 7).
A, Digital subtraction angiogram reveals the AVF draining into the right cavernous sinus.
B–E, Pretreatment dynamic MR images. In phase 0 (B) and in the first (C), second (D), and third (E) phases, the enhancement of the right side of the pituitary gland is delayed (arrow in C–E).
F–I, Posttreatment dynamic MR images in phase 0 (F) and in the first (G), second (H), and third (I) phases. After treatment of the disease, the pituitary gland is symmetrically enhancing on both the right and left sides, and the height of the pituitary gland decreased from 7 to 5 mm. Part of the posterior pituitary gland is seen as a hyperintense area in phase 0.
