Pregnancy luteoma. The peripheral-located multinodular ovarian masses (arrowheads) show intermediate high signal intensity on the coronal T1-weighted image (A, 101/4/1 [repetition time/echo time/excitation]), low signal intensity on the T2-weighted image (B, 4/90/1), and avid enhancement on the Gd-DTPA enhanced T1-weighted image (C, 101/4/1). Three weeks postpartum, the coronal Gd-DTPA enhanced T1-weighted image (D) show the greatly diminished size of the enhancing ovarian masses, although the ovaries (arrowheads) remain large.

These masses were characterized as intermediate high signal intensity on the T1-weighted images (Fig. 1A) and low signal intensity on T2-weighted images (Fig. 1B). The Gd-DTPA enhanced T1-weighted images (Fig. 1C) showed avid enhancement of the masses that indicated their solid nature and hypervascularity. The ovarian masses correspondingly decreased in size on both the follow-up US and MR imaging (Fig. 1D).
