Tumors and pseudotumors of the secondary müllerian system: Review with emphasis on cross-sectional imaging findings

OBJECTIVE. Microscopic structures lined by müllerian epithelium are frequently seen outside the uterus and fallopian tubes and are termed "müllerian rests" or "secondary müllerian system." Varied entities ranging from benign endosalpingosis to highly malignant ovarian tumors are thought to be derived from the secondary müllerian system. Cross-sectional imaging findings of diseases and disorders of the secondary müllerian system are presented here. CONCLUSION. Familiarity with a wide spectrum of diseases and disorders of the secondary müllerian system allows accurate diagnosis and management.
