Developmental venous anomalies on fetal magnetic resonance imaging: prevalence and reproducible radiological phenotypes.
Article in Pediatric radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundDevelopmental venous anomalies are the most common cerebral vascular malformations but remain underrecognized in fetuses. Accurate prenatal identification is important for diagnosis and counseling.
objectiveThis study aimed to describe the prevalence of developmental venous anomalies on fetal MRI and characterize their distinctive MRI patterns. MATERIALS AND
methodsA retrospective study of all fetal MRIs performed between January 2017 and June 2025. Cases with documented or suspected developmental venous anomalies were extracted, including a systematic re-evaluation of studies with susceptibility artifacts, to identify developmental venous anomalies not categorized initially as such. Two independent reviewers assessed the number, location, and drainage pattern (superficial, deep, or mixed) of developmental venous anomalies. Associated abnormalities, including varix thrombosis, parenchymal hemorrhage and volume loss, and vascular malformation, were recorded. Developmental venous anomalies with associated abnormalities or multiple developmental venous anomalies were classified as complicated developmental venous anomalies.
resultsAmong 3,932 fetuses, 18 (0.46%) had developmental venous anomalies (median gestational age 33 weeks (IQR, 32, 33); 13 males). Developmental venous anomalies were frontal in 10 (55.6%), parieto-occipital in 7 (38.9%), and parietal in 1 (5.6%); 14 (77.8%) were right-sided. Deep drainage occurred in 8/18 (44.4%), superficial in 4/18 (22.2%), and mixed in 6/18 (33.3%). Two reproducible MRI patterns were identified: the "fisherman's-rope" sign in superficial frontal developmental venous anomalies, and ventricular-wall T2 hypointensity in developmental venous anomalies with deep drainage. Eight fetuses (44.4%) had a complicated developmental venous anomaly. Multiple developmental venous anomalies (3/18, 16.7%) were associated with varix thrombosis (2/3 vs 0/15, P=0.02).
conclusionFetal developmental venous anomalies demonstrate two reproducible MRI patterns that enable confident diagnosis and help in differentiating from hemorrhage and other vascular malformations.
