Images of the complete hydatidiform mole. (a) Transvaginal ultrasonography (sagittal). (b) The magnetic resonance image (T2 weighted, sagittal) shows a massive intrauterine mass (19 × 15 × 10 cm) with many small vesicles, no normal gestational sac, and no fetus. (c) The macroscopic image of the expelled mole that has a classical bunch of grapes appearance. (d) The microscopic image (hematoxylin and eosin staining) shows the edematous and swollen villi with circumferential trophoblastic proliferation (as the arrow indicates).
