Progressive vascular tumor in infant: A case report and literature review of PIK3CA vascular malformation.
Review in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeVascular anomalies are classified as either vascular tumors or vascular malformations. Vascular malformations can be difficult to diagnose and treat in the pediatric population and can masquerade as malignant processes. Understanding the genetics behind vascular malformations can lead to identification of specific mutations which can be treated with targeted immunotherapy.
methodsOur case presents a pediatric patient with progressively enlarging vascular malformation despite multiple surgical resections and systemic medical treatments who underwent genetic evaluation and was found to have PIK3CA mutation.
resultsAfter identification of PIK3CA mutation, our patient was successfully treated with the p110ɑ-specific inhibitor, alpelisib, with both shrinkage of malformation on follow-up imaging as well as gains in her developmental milestones.
conclusionProgressive vascular malformations in the pediatric population can be hard to diagnose and treat and are thought to arise from somatic mutations. Our case highlights a patient with progressive malformation despite multiple surgical resections who was successfully treated with targeted immunotherapy after proper identification of genetic mutation.
