[An ultrasonic trap: pseudocystic degeneration of uterine myomas].

The authors present a rare case of pseudocystic degeneration of fibroids for which they had used an ultrasound scan before the operation. They point out that the ultrasound pictures they found were very similar indeed to those shown by patients with multiloculated ovarian cysts. They emphasize that ultrasound does have its limits in the diagnosis of pelvic tumours.
