Interesting neuroimaging findings in a child with hyperlipidemia: a case report.
Article in BMC pediatrics, 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
introductionNeurological manifestations are rare in hyperlipidemia; however, extreme hypertriglyceridemia may cause “milky” blood and cerebrospinal fluid (CSF) and may compromise the central nervous system. We report an infant with familial hyperlipidemia who presented with seizures and unusual neuroimaging findings, including fat deposition in the cerebral vasculature and intracranial xanthomas. CASE DESCRIPTION: A 2-month-old boy, previously healthy, presented with fever, followed by a focal seizure. His parents are consanguineous. His perinatal history and early development are unremarkable. Physical examination revealed no abnormal findings. During phlebotomy, the blood appeared lipemic with a distinctive ‘salmon-colored’ hue. Laboratory work-up revealed severe hypertriglyceridemia with normal pancreatic enzymes; other metabolic, hematologic, and infectious evaluations were unremarkable. Non-contrast brain CT and MRI showed fat within the dural venous sinuses and cortical veins, along with two extra-axial, fat-containing intracranial lesions in the left parietal and right frontal regions. The patient was treated with anticonvulsant medications, antiplatelet therapy, and a specialized low-fat formula, resulting in significant improvement in lipid levels and clinical stabilization. DISCUSSION: In severe hypertriglyceridemia causing visible lipemia of blood, blood viscosity increases and perfusion in the microcirculation can be impaired. Hyperviscosity and the toxic effect of lipid particles on the endothelium may lead to vascular injury in the brain. Accumulation of lipid in intracranial blood vessels can extravasate through the injured blood-brain barrier to CSF and brain parenchyma. Intracranial xanthoma, parenchymal hemorrhage and infarction are considered as the complications.
conclusionsIn infants presenting with seizures or stroke-like signs alongside lipemic blood, clinicians should consider hyperlipidemia-induced neurovascular injury. Neuroimaging signs such as fat-density vessels or lesions should prompt an evaluation for dyslipidemia.
