Massive ovarian edema revealing gastric carcinoma: a case report.

Tumor-like enlargement of the ovaries due to accumulation of edema fluid within the ovarian stroma is referred to as massive ovarian edema (MOE). The pathogenesis of MOE is thought to be intermittent torsion of the ovary on its pedicle, causing partial obstruction of venous and lymphatic drainage. The diagnosis of MOE is based on imaging techniques. The case described here due to ovarian lymphatic vessel obstruction by carcinoma cells shows that metastatic disease may be a cause of MOE.
