Abstract
Extensive hydropic degeneration in uterine leiomyoma is a rare occurrence and is commonly
reported in association with pregnancy. It is a close mimicker of malignancy due to
rapid growth and atypical imaging appearances. Awareness of the imaging features helps
in diagnosis, avoids unnecessary patient anxiety, and hence reassurance especially
when encountered in pregnancy. We report two cases of extensive hydropic degeneration
of leiomyoma in nonpregnant females with imaging and histopathology correlation. We
also propose the “split fiber” sign as a useful magnetic resonance imaging feature
for diagnosing this condition.
