[Bilateral massive ovarian edema: a case report including MR findings and etiology].

A 42-year-old woman with bilateral massive ovarian edema (MOE) is presented. MOE is usually seen in women 6 to 33 years of age. Therefore, accurate re-operative assessment of MOE is important to avoid unnecessary oophorectomy procedures. MR findings of MOE are characteristic and reflect very well the diffuse stromal edema noted on microscopy. The etiology and MR findings of MOE are discussed.
