“…We found that this type of tumor is usually cystic, variable from purely cystic to predominently solid on imaging as in other reports [6,11,12,15,16]. In our series, solid component were found in 50.0% of the tumors, a lower rate than that reported by Atri et al (80.3%) [16] but similar to that reported by Alcázar et al (56.5%) [11].…”

“…Although the real incidence of false-positive findings of malignancy of ovarian cystadenofibroma is uncertain, some investigators have reported that this type of tumor could be diagnosed as malignancy on imaging [6,11,16,19]. In our series, 14 benign cystadenofibromas (serous in 13 and endometrioid in 1) had the imaging features considered to be typical of borderline or malignant on CT or MR imaging according to the criteria of malignant epithelial ovarian tumors described in other reports [13]; thus, 14 tumors of 29 pathologically proven benign cystadenofibromas (48.3%) were incorrectly characterized as malignant on the preoperative imaging studies.…”

CT and MRI findings of cystadenofibromas of the ovary

The aim of this study was to assess imaging findings on CT or MR images of histologically proven ovarian cystadenofibromas. In the period 1995-2001, 32 histologically proven ovarian cystadenofibromas were identified in 28 women. Of the 32 ovarian cystadenofibromas, 16 tumors were purely cystic and the remaining 16 were complex cystic on CT or MR images. Solid components of 16 complex cystic tumors were seen as nodular ( n=8) or trabecular ( n=9) solid areas. One tumor had both nodular and trabecular solid components. Among 16 complex cystic tumors, 14 had thick or irregular septa; thus, half of ovarian cystadenofibromas had morphological imaging features of malignancy on CT or MR images. On histology, solid components in the cystic tumors were correlated with fibrous stromas that occasionally made a false-positive result for malignancy on imaging.

“…Teratomas typically present as echo- (44) and (9). Rectovaginal pouch adhesions are frequently associated with endometriosis but are not classified as deeply infiltrating lesions genic masses with acoustic shadowing due to hairballs or calcifications such as teeth or bone in the Rokitanski protruberance [17]. Layered lines and dots, fat-fluid level, and isolated bright echogenic foci with acoustic shadowing are characteristic sonographic findings of dermoid cysts [18].…”

Endometriosis corresponds to ectopic endometrial glands and stroma outside the uterine cavity. Clinical symptoms include dysmenorrhoea, dyspareunia, infertility, painful defecation or cyclic urinary symptoms. Pelvic ultrasound is the primary imaging modality to identify and differentiate locations to the ovary (endometriomas) and the bladder wall. Characteristic sonographic features of endometriomas are diffuse low-level internal echos, multilocularity and hyperchoic foci in the wall. Differential diagnoses include corpus luteum, teratoma, cystadenoma, fibroma, tubo-ovarian abscess and carcinoma. Repeated ultrasound is highly recommended for unilocular cysts with low-level internal echoes to differentiate functional corpus luteum from endometriomas. Posterior locations of endometriosis include utero-sacral ligaments, torus uterinus, vagina and recto-sigmoid. Sonographic and MRI features are discussed for each location. Although ultrasound is able to diagnose most locations, its limited sensitivity for posterior lesions does not allow management decision in all patients. MRI has shown high accuracies for both anterior and posterior endometriosis and enables complete lesion mapping before surgery. Posterior locations demonstrate abnormal T2-hypointense, nodules with occasional T1-hyperintense spots and are easier to identify when peristaltic inhibitors and intravenous contrast media are used. Anterior locations benefit from the possibility of MRI urography sequences within the same examination. Rare locations and possible transformation into malignancy are discussed.

“…Non-neoplastic cystic lesions containing FFLs were mostly composed of endometriotic cysts, followed by hemorrhagic corpus luteal cysts. Endometriotic cysts are commonly the result of repeated cyclic bleeding, and corpus luteal cysts may undergo hemorrhage [15,16]. It is not unexpected that FFLs were also often found in malignant tumors, in view of their aggressiveness.…”

MR features of fluid-fluid levels in ovarian masses

et al. 2007

To evaluate retrospectively the frequency and imaging features of fluid-fluid levels (FFLs) in pathologically proven ovarian masses on magnetic resonance (MR) images. The authors reviewed the preoperative MR findings of 556 ovarian masses in 428 patients. Presence, numbers, and signal intensities (SI) of FFLs were analyzed. In non-teratomas, we assessed whether SI of the FFLs of benign masses and malignant neoplasms differed using the chi(2) test. FFLs were observed in 66 of 556 ovarian masses (11.9%) on MR images, fat-fluid levels were observed in 11 of 80 teratomas, and FFLs attributed to hemorrhage in 54 of 476 non-teratomas and one twisted teratoma. Non-neoplastic cystic lesions were most common non-teratomas to contain FFLs (27/197, 13.7%), followed by malignant neoplasms (23/177, 13.0%). Benign neoplasms rarely contained FFLs (4/102, 3.9%); those that did were commonly associated with complications such as torsion or inflammation. A hypointense supernatant layer together with a hyperintense dependent layer on T1-weighted images (T1WIs) was significantly more common in malignant neoplasms than in benign masses (P < 0.0001). FFLs occurred in various ovarian masses ranging from benign to malignant neoplasms on MR images. In non-teratomas, a hypointense supernatant layer and a hyperintense dependent layer on T1WIs may favor a diagnosis of malignancy.
