“…They are typically homogeneous, well-encapsulated masses that show decreased signal intensity on both T1-and T2-weighted MRI images [16]. However, once adnexal torsion occurs, these tumors develop hemorrhage and necrosis of the tumor tissue, showing areas of high signal intensity on both T1-and T2-weighted MR images due to passive congestion of the mass [17]. In the present study, cases of adnexal torsion caused by fibroma and thecoma, respectively, were treated by laparoscopic surgery.…”

Fourteen cases of laparoscopically treated solid/ predominantly solid nonepithelial adnexal tumors are presented. Unilateral salpingo-oophorectomy was performed in seven cases [three fibromas, one thecoma, one strumal carcinoid, one Sertoli-Leydig cell tumor (G2), and one dysgerminoma], including a 21-year-old patient with fibroma with adnexal torsion. A 26-year-old patient with fibroma was treated by tumorectomy. Laparoscopicassisted vaginal hysterectomy and bilateral salpingooophorectomy were done in five cases [three thecomas, one adult-type granulosa cell tumor, one Sertoli-Leydig cell tumor (G2)], including a 52-year-old patient with thecoma complicated by torsion. In a case of adenomatoid tumor of the fallopian tube, unilateral salpingectomy was done. Adjuvant platinum-based chemotherapy was added in a case of dysgerminoma, and there has been no sign of recurrence after 3 years.

“…Hyperintense signal of enlarged ovarian stroma on T2-weighted images probably related to edema can be useful findings in viable torsions [18,19]. When hemorrhagic necrosis occurs, the lesion may exhibit high intensity on T1-weighted images [17,20]. Identification of the enhancement on postcontrast MR images is an important finding for suggesting the viable tissues in the affected ovary [19].…”

MR features of physiologic and benign conditions of the ovary

In reproductive women, various physiologic conditions can cause morphologic changes of the ovary, resembling pathologic conditions. Benign ovarian diseases can also simulate malignancies. Magnetic resonance imaging (MRI) can play an important role in establishing accurate diagnosis. Functional cysts should not be confused with cystic neoplasms. Corpus luteum cysts typically have a thick wall and are occasionally hemorrhagic. Multicystic lesions that may mimic cystic neoplasms include hyperreactio luteinalis, ovarian hyperstimulation syndrome, and polycystic ovary syndrome. Recognition of clinical settings can help establish diagnosis. In endometrial cysts, MRI usually provides specific diagnosis; however, decidual change during pregnancy should not be confused with secondary neoplasm. Peritoneal inclusion cysts can be distinguished from cystic neoplasms by recognition of their characteristic configurations. Ovarian torsion and massive ovarian edema may mimic solid malignant tumors. Recognition of normal follicles and anatomic structures is useful in diagnosing these conditions. In pelvic inflammatory diseases, transfascial spread of the lesion should not be confused with invasive malignant tumors. Radiologic identification of abscess formation can be a diagnostic clue. Many benign tumors, including teratoma, Brenner tumor, and sex-cord stromal tumor, frequently show characteristic MRI features. Knowledge of MRI features of these conditions is essential in establishing accurate diagnosis and determining appropriate treatment.

Magnetic resonance imaging (MRI) is an accepted imaging method for diagnosing diseases of the female pelvis. This review article describes the role of MR imaging for the diagnosis of benign and malignant pelvic tumors. Sagittal T2-weighted fast spin echo sequences can be effectively applied to diagnose leiomyomas of the uterus and provide exact pretreatment measurements of size and localization. In the diagnostic work-up of endometrial carcinoma, fat-saturated, T1-weighted gradient echo sequences make it possible to determine precisely how deep myometrial infiltration extends and what tissue should be included in preoperative treatment planning. In cervical cancer staging, MRI permits both assessment of local tumor extent and determination of tumor volume for planning and monitoring radiotherapy. The usefulness of MRI in cervical cancer staging is, however, limited since not all early-stage cancer (FIGO stage IA and small stage IB tumors) can be detected. Hence, it appears that the use of MRI as a screening method for cervical cancer cannot be recommended. MRI can distinguish between benign and malignant ovarian tumors with high sensitivity and specificity. Standard and fat-saturated T1-weighted sequences usually can diagnose teratomas with a specificity of 100 %. Axial fat-saturated, contrast enhanced T1-weighted spin echo sequences are useful in the staging of malignant ovarian tumors since they facilitate evaluation of their internal structure and will disclose peritoneal metastases. Besides staging of ovarian cancer, MRI can be applied for localization and for monitoring treatment response.
