Giant endometrioma in an asymptomatic patient.

Endometriosis is a chronic inflammatory gynecologic disorder characterized by the presence of endometrial-like tissue, including endometrial glands and stroma, outside of the uterine cavity. It is a prevalent condition worldwide, affecting approximately 10% of reproductive-age women and up to 50% of infertile women. Endometriosis manifests in three ways: superficial peritoneal endometriosis, deep infiltrative endometriosis, and ovarian endometriomas, with the possibility of coexistence among them. The disease presents with a range of symptoms, including chronic pelvic pain, dysmenorrhea, dyspareunia, and infertility. Additionally, patients may experience nongynecological symptoms such as dyschezia, dysuria, hematuria, flank pain, and fatigue, among others. The ovaries are the most affected site in endometriosis, typically with cysts measuring less than 6 cm in diameter. Therefore, even in the presence of a large ovarian cyst or in asymptomatic patients, the consideration of an endometrial cyst should not be overlooked.

Abdominal gastrointestinal imaging findings on computed tomography in patients with COVID-19 and correlation with clinical outcomes.

PURPOSE: Pulmonary imaging finding of Coronavirus disease 2019 (COVID-19) has been widely described, but until now few studies have been published about abdominal radiological presentation. The aim of this study was to provide an overview of abdominal imaging findings in patients with COVID-19 in a multicenter study and correlate them with worse clinical outcomes. MATERIALS AND METHODS: This retrospective study included adult COVID-positive patients with abdominal CT performed from 4/1/2020 to 5/1/2020 from two institutions. Demographic, laboratory and clinical data were recorded, including clinical outcomes. RESULTS: Of 81 COVID-positive patients, the average age was 61 years, 42 (52%) women and 45 (55%) had positive abdominopelvic findings. The most common abdominal imaging features were intestinal imaging findings (20/81, 24%), including colorectal (4/81, 5%) and small bowel thickening (10/81, 12%), intestinal distension (15/81, 18%), pneumatosis (1/81, 1%) and intestinal perforation (1/81, 1%). On multivariate analysis, intestinal imaging findings were associated with higher risk of worse outcome (death or invasive mechanical ventilation) (RR = 2.6, p = 0.04) and higher risk of invasive mechanical ventilation alone (RR = 6.2, p = 0.05). CONCLUSION: Intestinal abnormalities were common findings in COVID-19 patients who underwent abdominal CT and were significantly correlated to worse outcomes in the clinical follow-up.

Is possible to rule out clinically significant prostate cancer using PI-RADS v2 for the assessment of prostate MRI?

ABSTRACT Objectives To evaluate the diagnostic performance and interobserver agreement of PI-RADS v2. Materials and Methods In this Institutional Review Board approved single-center retrospective study, 98 patients with clinically suspected PCa who underwent 3-T multiparametric MRI followed by MRI/TRUS fusion-guided prostate biopsy were included from June 2013 to February 2015. Two radiologists (R1 and R2) with 8 and 1 years of experience in abdominal radiology reviewed the MRI scans and assigned PI-RADS v2 scores in all prostate zones. PI-RADS v2 were compared to MRI/TRUS fusion-guided biopsy results, which were classified as negative, PCa, and significant PCa (sPCa). Results Sensitivity, specificity, NPV, PPV and accuracy for PCa was 85.7% (same for all metrics) for R1 and 81.6%, 79.6%, 81.2%, 80.0% and 80.6% for R2. For detecting sPCa, the corresponding values were 95.3%, 85.4%, 95.9%, 83.7% and 89.8% for R1 and 93.0%, 81.8%, 93.7%, 86.7% and 86.7% for R2. There was substantial interobserver agreement in assigning PI-RADS v2 score as negative (1, 2, 3) or positive (4, 5) (Kappa=0.78). On multivariate analysis, PI-RADS v2 (p <0.001) was the only independent predictor of sPCa compared with age, abnormal DRE, prostate volume, PSA and PSA density. Conclusions Our study population demonstrated that PI-RADS v2 had high diagnostic accuracy, substantial interobserver agreement, and it was the only independent predictor of sPCa.

Torsion of a giant antimesenteric lipoma of the sigmoid: a rare cause of acute abdomen.

Lipomas of the gastrointestinal tract are uncommon benign tumors of mature adipocytes and may occur in any portion along the gut. Depending on location they may have a variety of clinical presentations and even simulate malignant neoplasms. We report a case of a 58-year-old woman who presented with acute pelvic pain. An emergency sonogram detected a hyperechogenic mass in the left adnexal region, with no vascularization on Doppler. A computed tomography confirmed the hypothesis of a fat containing tumor with signals of torsion. The patient underwent laparoscopy which depicted a mass over the antimesenteric side of the sigmoid with signs of ischemia and twisted vascular pedicle. The lesion was resected, and the microscopy confirmed the diagnosis of lipoma. The multidisciplinary team in the emergency room must be aware of these possible complications in order to optimize patient care.

Os três líquens: escleroso, plano e plano erosivo / The three lichens: sclerosus, planus and erosive

Líquen escleroso (LE) e líquen plano (LP) são doenças de natureza inflamatória que atacam a pele e a região anogenital e que, por vezes, podem ser de difícil diferenciação clínica em seus respectivos estágios iniciais. O LE teve sua incidência demonstrada em 1,7% dos atendimentos ginecológicos, em todas as faixas etárias. Já o LP ataca cerca de 1% das mulheres, mas sua incidência real é difícil de avaliar. LE e LP são doenças cuja patogênese é multifatorial. Fatores genéticos e hormonais e infecções e trauma foram associados ao desenvolvimento de LE, enquanto que LP tem seu desenvolvimento menos compreendido; no entanto, também é associado a fatores genéticos, a infecções e ao uso de certos medicamentos. As duas doenças causam bastante desconforto às pacientes, pois podem se apresentar com dor, ardência, prurido e também há a possibilidade de estenose do introito vaginal e consequente dispareunia. Na suspeita de LE e LP, deve ser feito diagnóstico diferencial com outras doenças de pele e com neoplasia intraepitelial vulvar (NIV). O risco de transformação maligna justifica o acompanhamento que as pacientes devem ter pelo resto da vida. O tratamento de primeira linha para LE e LP consiste em corticosteroides tópicos superpotentes. O diagnóstico requer frequente biópsia para sua confirmação. O objetivo deste trabalho foi revisar a fisiopatologia, complicações e tratamento dessas duas doenças, as quais são muito importantes, pois não possuem cura e podem comprometer seriamente a qualidade de vida das pacientes.(AU)

Lichen sclerosus (LS) and lichen planus (LP) are diseases of an inflammatory nature that attack the skin and anogenital region, and sometimes they might have a difficult clinical differentiation in their early stages. LE has its incidence demonstrated in 1.7% of gynecological consultations in all age groups. LP attacks about 1% of women, but its true incidence is difficult to assess. LE and LP are diseases whose pathogenesis is multifactorial. Genetic and hormonal factors, infections and trauma were associated with the development of LE, while LP has its development less understood; however, it is also associated with genetic factors, infections and the use of certain medications. Both diseases cause much discomfort to the patient, because they may present with pain, burning, itching and there is also the possibility of stenosis of the vaginal opening and consequent dyspareunia. On suspicion of LE and LP should be done differential diagnosis with other skin diseases and vaginal intraepithelial neoplasia (VIN). The risk of malignant transformation justifies the monitoring that patients should have in the rest of their life. The first-line treatment for LE and LP consists of topical corticosteroids super powerful. The diagnosis often requires biopsy for confirmation. The aim of this study was to review the pathophysiology, complications and treatment of these diseases, which are very important because they have no cure and can seriously compromise the quality of life of patients.(AU)
