RESUMEN
Although endometriosis is a common gynecological condition in women of reproductive age, a complication of endometriosis is rarely considered as the differential diagnosis of acute abdominal pain in that context. However, acute events in women with endometriosis can represent life-threatening conditions, which require emergent treatment and often surgical management. Mass effect of endometriotic implants can give rise to obstructive complications, specifically occurring in the bowel or in the urinary tract, while inflammatory mediators released by ectopic endometrial tissue can lead to inflammation of the surrounding tissues or to superinfection of the endometriotic implants. Magnetic resonance imaging is the best imaging modality to reach the diagnosis of endometriosis, but an accurate diagnosis is possible on computed tomography, especially in the presence of stellar, mildly enhanced, infiltrative lesions in suggestive areas. The aim of this pictorial review is to provide an image-based overview of key findings for the diagnosis of acute abdominal complications of endometriosis.
RESUMEN
PURPOSE: Isolated Fallopian tube torsion (IFTT) is a rare cause of acute pelvic pain in women of reproductive age. Preoperative diagnosis is rarely made, even though an early surgery is necessary to preserve women's fertility. This study aims to identify simple and reproductible imaging features for the diagnosis of IFTT on sectional imaging. METHODS: We conducted a retrospective, cross-sectional study on patients diagnosed with IFTT in our center between January 2008 and December 2021. The CTs and MRIs of 16 patients with surgically proven IFTT were retrospectively and independently reviewed by two radiologists to identify the relevant findings for the diagnosis. RESULTS: The median patient age was 29 years (range: 13-63 years). Only four patients (25 %) had a conservatory treatment. Two patterns of IFTT were identified on CT and MRI. The first pattern (n = 6, 37 %) consisted of a thin-walled hydrosalpinx, U- or C-shaped, with a median diameter of 3 cm. The second pattern (n = 10, 63 %) consisted of an extra-ovarian cyst adjacent to a soft tissue mass containing the twisted tube and vessels. In 15 patients (94 %), the ipsilateral ovary was of normal size. Hematosalpinx was observed in 3 patients with necrosis of the tube on pathological reports (19 %). Interobserver agreement was substantial or good for all criteria. CONCLUSIONS: An association of simple and reproductible features can support the diagnosis of IFTT on sectional imaging in an emergency context: the identification of these features may avoid a delayed surgical treatment, which could otherwise compromise women's fertility.

OBJECTIVE: To determine whether the total small vessel disease (SVD) score adds information to the prediction of stroke outcome compared to validated predictors, we tested different predictive models of outcome in patients with stroke. METHODS: White matter hyperintensity, lacunes, perivascular spaces, microbleeds, and atrophy were quantified in 2 prospective datasets of 428 and 197 patients with first-ever stroke, using MRI collected 24 to 72 hours after stroke onset. Functional, cognitive, and psychological status were assessed at the 3- to 6-month follow-up. The predictive accuracy (in terms of calibration and discrimination) of age, baseline NIH Stroke Scale score (NIHSS), and infarct volume was quantified (model 1) on dataset 1, the total SVD score was added (model 2), and the improvement in predictive accuracy was evaluated. These 2 models were also developed in dataset 2 for replication. Finally, in model 3, the MRI features of cerebral SVD were included rather than the total SVD score. RESULTS: Model 1 showed excellent performance for discriminating poor vs good functional outcomes (area under the curve [AUC] 0.915), and fair performance for identifying cognitively impaired and depressed patients (AUCs 0.750 and 0.688, respectively). A higher SVD score was associated with a poorer outcome (odds ratio 1.30 [1.07-1.58], p = 0.0090 at best for functional outcome). However, adding the total SVD score (model 2) or individual MRI features (model 3) did not improve the prediction over model 1. Results for dataset 2 were similar. CONCLUSIONS: Cerebral SVD was independently associated with functional, cognitive, and psychological outcomes, but had no clinically relevant added value to predict the individual outcomes of patients when compared to the usual predictors, such as age and baseline NIHSS.

BACKGROUND: Metastatic colorectal cancer (mCRC) is increasingly treated using targeted therapies. Their real-life evaluation is insufficient, especially in elderly and frail patients. The aim was to describe use, safety, and effectiveness of targeted therapies in first-line mCRC treatment according to age. PATIENTS AND METHODS: Two field cohorts of patients initiating bevacizumab or cetuximab for first-line mCRC were pooled. Patients characteristics, use, and safety were compared between younger and elderly patients (<75 vs. ≥75 years). Two-year overall survival (OS) and progression-free survival (PFS) were estimated in both age groups using the Kaplan-Meier method adjusted on factors associated with death or progression identified with Cox multivariate modeling. RESULTS: Eight hundred patients (n = 411, 51.4% bevacizumab) were included: 498 (62.3%) male, median age 64 years, 118 (14.8%) Eastern Cooperative Oncology Group performance status (ECOG-PS) ≥2. Elderly patients (n = 126, 15.8%) were more often treated with 5-fluorouracil alone than younger. Severe adverse events were equivalent across age groups. ECOG-PS ≥1, abnormal hemoglobin, and abnormal alkaline phosphatases were associated with a higher risk of death; OS adjusted on these factors was similar between elderly and younger patients. ECOG-PS ≥1, lung metastases, abnormal hemoglobin, and abnormal creatinine clearance were associated with a higher risk of progression or death; PFS adjusted on these factors was similar across groups. CONCLUSION: Despite treatment adaptations, elderly patients could benefit from targeted therapies as younger without safety warning.
