Massive ovarian edema is an unusual cause of ovarian enlargement in yo
ung patients. Most cases are thought to result from venous and lymphat
ic obstruction, producing edema. We report the case of a 15-year-old g
irl with bilateral massive ovarian edema, findings on ultrasound imagi
ng, and a review of the literature. The sonographic appearance is non-
specific and can mimic neoplasia, and the definitive diagnosis require
s histological examination. It is, however, an important condition to
consider in a young patient with a complex ovarian mass in an appropri
ate clinical setting, as conservative treatment with ovarian preservat
ion is often possible.
