Robert's uterus is a unique malformation, described as a septate uterus with a non-communicating hemicavity, consisting of a blind uterine horn usually with unilateral hematometra, a contralateral unicornuate uterine cavity and a normally shaped external uterine fundus. The main symptom in affected young women is pelvic pain that becomes intensified near menses. We describe the case of a 22-year-old woman who was referred for diagnostic assessment and treatment of a congenital uterine anomaly. We used three-dimensional sonohysterography with volume-contrast imaging, HDLive rendering mode and automatic volume calculation (SonoHysteroAVC) for the diagnosis, surgical planning and postoperative evaluation. These imaging techniques provided a complete understanding of the internal and external uterine structures, enabling us to perform a minimally invasive hysteroscopic metroplasty, guided by transrectal ultrasound, and therefore avoiding the need for laparotomy/laparoscopy. The outcome of treatment was considered satisfactory; menstruation ceased to be painful and, after two hysteroscopic procedures, the communicating 0.3-cm3 hemicavity was visualized as a 3.6-cm3 normalized uterine cavity using the same imaging techniques. The findings of this case report raise questions about the embryological origin of Robert's uterus, the suitability of current classification systems, and the role of more invasive approaches (laparoscopy/laparotomy) and surgical procedures (horn resection/endometrectomy) that do not aim to improve uterine cavity shape and volume in women with this condition.

ABSTRACT Objectives To evaluate the accuracy of transvaginal three-dimensional ultrasound with volume contrast imaging ( VCI) for preoperative assessment of depth of myometrial invasion and cervical involvement in women with endometrial cancer. Methods Transvaginal volume acquisition of the uterus was performed in 60 consecutive patients with histological diagnosis of endometrial cancer who were scheduled for primary surgical treatment. Depth of myometrial invasion and presence or absence of cervical involvement were assessed using VCI in multiplanar display mode. Results were compared to final postoperative histopathological findings. Patients with histological high-risk cell types, including Grade 3 endometrioid adenocarcinoma, clear cell carcinoma, papillary serous carcinoma and carcinosarcoma, were excluded. Results Forty patients were included in the analysis. The accuracy of VCI in assessing single-stage myometrial invasion (superficial or deep) was 92.5%. In the prediction of deep myometrial invasion, sensitivity, specificity, PPV and NPV of VCI were 100%, 89.7%, 78.6% and 100%, respectively. The accuracy of VCI in assessing cervical involvement was 90.0%. Sensitivity, specificity, PPV and NPV of VCI in predicting the presence of cervical involvement were 100%, 86.2%, 73.3% and 100%, respectively. Conclusion Transvaginal VCI is an uncomplicated method that is able to predict with reasonable accuracy the depth of myometrial invasion and cervical involvement in women with endometrial cancer.

Objectives To describe the normal appearance and study the biometry of the fetal cerebellar vermis by three-dimensional (3D) volume contrast imaging in the coronal (C-) plane (VCI-C). Methods A total of 203 normally developed fetuses were examined prospectively at 18–33 weeks' gestation. At the level of the view used to measure the transverse cerebellar diameter (TCD), a VCI-C plane was displayed to examine, using a transabdominal probe, the fetal mid-saggital vermis. The volumes acquired were stored for later review and measurement of the anteroposterior (AP) diameter, craniocaudal (CC) diameter and surface area of the cerebellar vermis. Each dataset was evaluated by two independent observers. Measurements as a function of gestational age (GA), biparietal diameter (BPD), head circumference (HC) and TCD were expressed by regression equations. Interobserver variability was evaluated. Nomograms were produced. In order to validate the use of VCI in fetal biometry, datasets from 57 patients were selected arbitrarily for comparison of their VCI-C measurements with those from mid-sagittal sections of a stored 3D multiplanar examination. Intraclass correlation was used to evaluate the agreement between these measurements. Results The mean maternal age was 32 years. We were able to measure mid-sagittal CC diameter, mid-sagittal AP diameter and cerebellar vermis surface area in all fetuses. Interobserver variability analysis showed no significant differences between the two observers (P > 0.05). Measurements of the cerebellar vermis (AP diameter, CC diameter and surface area) correlated linearly with GA, BPD, HC and TCD (r ≥ 0.82, P < 0.0001). CC and AP diameters estimated from the mid-sagittal section of the multiplanar measurements were significantly correlated with VCI-C measurements (r = 0.96, P< 0.00001 and r = 0.95, P< 0.00001, respectively). Conclusions VCI-C is a valuable tool, allowing intrauterine assessment of the normal appearance of the fetal cerebellar vermis. The nomograms developed in this study should enable accurate evaluation of the cerebellar vermis. [ABSTRACT FROM AUTHOR]
