Torcular pseudomass is frequently detected on fetal magnetic resonance imaging and reduces with gestational age.
Review in Pediatric radiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe torcular pseudomass is an incidental extra-axial midline mass located between the venous sinuses and the occipital squama in the pediatric population. Although this structure is presumed to be a developmental feature, it has not been characterized on fetal MRI.
objectiveTo determine the frequency, imaging features and longitudinal in utero evolution of torcular pseudomass using fetal MRI. MATERIALS AND
methodsWe present a single-center retrospective study of fetal MRI performed at a tertiary hospital. Two independent reviewers first ordinally scored torcular pseudomass as absent, focal, crescentic or bulky based on morphology. We reviewed available follow-up fetal and postnatal MRI and further classified torcular pseudomass as stable, involuted or progressive. We also collected clinical and demographic data from electronic charts and compared them among categories, corrected for multiple comparisons.
resultsThis study included a total of 219 fetuses with median gestational age of 28 weeks (interquartile range [IQR]: 23-32 weeks). Torcular pseudomass was absent in 8% (n=17) and present as a focal mass in 15% (n=33), crescentic in 45% (n=98) and bulky in 32% (n=71) of the cases. Median gestational age was statistically different among torcular pseudomass categories and inversely associated with size. Follow-up fetal MRI was available in 9.6% (n=21) of cases (median interval 4 weeks; IQR: 2-9 weeks) and torcular pseudomass in these cases was classified as stable in 67% (n=14), involuted in 29% (n=6) and progressive in 5% (n=1). Postnatal MRI was available in 5% (n=12) of fetuses (median interval 11.5 months, IQR: 3-17 months), and among these cases torcular pseudomass was classified as stable in 33% (n=4) and involuted in 67% (n=8).
conclusionTorcular pseudomass is highly prevalent in the fetal population and shows a natural tendency to involute, even in utero, although it sometimes persists during early infanthood.
