A case of radiologically identified molar invasion into extensive arteriove
nous shunts (AVSs) is described. CT and MRI revealed a large uterine mass,
accompanied by multiple AVSs. Dynamic MRI and pelvic angiography demonstrat
ed multiple trophoblastic cysts invading into the AVSs. Resected specimen c
onfirmed the diagnosis of invasive mole. Dynamic MRI was very useful in det
ermining the etiology of AVS. (C) 2001 Elsevier Science Inc. All rights res
