Sub-Ependymal Pseudocysts and Lenticulostriate Vasculopathy
Bibliographic record
Abstract
Abstract Small sub-ependymal pseudocysts, usually located around or in the walls of the anterior horns of the lateral ventricles or in the caudo-thalamic notches, and linear echodensities, usually located in the basal ganglia (lenticulostriate vasculopathy [LSV]), are common findings on cranial ultrasound scans in newborn infants. The findings can give rise to considerable alarm, especially to parents. However, they are usually benign and very rarely cause problems. This is particularly so when they are isolated and found on screening ultrasound scans in infants without neurological symptoms, though testing for cytomegalovirus should be considered. But sub-ependymal pseudocysts, especially if more extensive and with LSV, can, however, be clues to underlying and serious diagnoses, especially in symptomatic infants. Awareness of the conditions in which these findings may occur can lead to early focused investigation as they are usually present on the admission scan. It is also important not to mistake the cysts for other pathology such as cystic white matter injury, porencephalic cysts, or intraparenchymal hemorrhage. This chapter is a guide to the appearance and known associations of sub-ependymal pseudocysts and LSV.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
