Background: Massive ovarian edema is a very rare condition characterized by a tumorlike enlargement of the ovary. The ultrasound findings have been reported as a solid tumorlike mass or as a solid mass containing a cystic component
Case: Our 30 years old case presented with acute abdomen syndrome in 13th week of gestation. The color doppler sonographic evaluation revealed right ovary as a solid mass, 90*50 mm in diameter with increased vascularity and increased ovarian arterial blood flow. A right salpingo-oopherectomy was performed by exploratory laparotomy. As a result of histopathologic examination, massive ovarian edema was diagnosed.
Conclusion: The sonographic appereance is nonspecific and the definitive diagnosis requires histological examination. The consideration of this rare entity is important to prevent incorrect treatment.
