Striking corpus callosum lesions in immediate cerebral fat embolism: A rare clinical case.
Article in Trauma case reports, 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
Fat embolism syndrome (FES) is a known complication of long-bone fractures, typically occurring 24-48 h post-trauma and characterized by petechial rash, neurological symptoms, and pulmonary distress. Cerebral fat embolism (CFE), which can be fatal, can result from brain emboli. We report a case of a 17-year-old male who sustained bilateral closed femur fractures in a road traffic accident. The patient presented with immediate neurological distress, including coma, without respiratory symptoms. The brain's CT scan was normal initially. Still, an MRI later showed signs of FES, such as T2 and diffusion hyperintensities on the corpus callosum, a lipid peak on spectroscopy, and a microbleed. Delayed awakening and status epilepticus, treated with anticonvulsants, complicated the patient's course. This case highlights the diagnostic utility of MRI in detecting CFE. It emphasizes the need to consider FES in isolated neurological symptoms following long-bone fractures, even without respiratory distress. Early surgical fixation of fractures remains critical for prevention.
